5. General.

a. Army Hearing Program.

The Army Hearing Program (AHP) represents leadership policies, strategies and processes to prevent noise induced hearing loss among military and Department of Defense (DoD) civilian personnel.

The hearing program has four major elements:
hearing readiness,
clinical hearing services,
operational hearing services, and
hearing conservation.

Good hearing enables a Soldier and/or civilian employee to maintain critical situational awareness and effective voice communication in any environment (i.e. garrison, industrial, training, operational and combat missions). This is accomplished by:

1) preventing both temporary and permanent hearing loss, and
2) improving communication in noise (signal-to-noise or S/N ratio).

Civilian personnel will be enrolled in a comprehensive hearing conservation program (HCP) when duties require exposure to hazardous noise or suspected ototoxins (ear poisons).

DA Pam 40-501, para 3-3 provides definitions of hazardous exposures.

Appendix D provides examples of typical exposures that meet the criteria for enrollment in a comprehensive HCP.

All Soldiers, due to military training requirements known to be noise hazardous, are automatically enrolled in the HCP.

b. Hearing loss degrades combat readiness and effectiveness. On today’s advanced technology battlefield, Soldiers must be prepared to communicate effectively and perform optimally, which requires essentially normal hearing sensitivity. Good hearing is a proven combat multiplier, preserving the lethality and survivability of the War Fighter.

c. Noise-induced hearing loss is one of the most prevalent injuries among military and civilian personnel, representing a significant portion of the annual cost for service-connected disability compensation. Hearing loss and/or its associated symptoms (i.e.; tinnitus) result in permanent disability, which in most cases is preventable. It is imperative that emphasis on hearing conservation and preventive measures be maintained. The primary goal of the Army Medical Department is Force Health Protection. Hearing loss prevention is consistent with the goal to prevent or eliminate disease and non-battle related injuries.

d. Nuisance noise is defined as any unwanted sound that interferes with communication or the ability to achieve restful sleep periods.

- It capitalizes on the non-auditory effects of noise, creating stress and fatigue in dangerous combinations for Soldiers and civilians.

- Acceptable noise levels are task-specific, for example, the amount of tolerable ambient noise is greater for a TOC than for a sleep tent.

- The presence of unwanted or intrusive noise has been heavily researched and the resulting insights can assist in short and long-term care of the deployed Soldier at all ranks.

- Preservation of communication ease, including face-to-face briefings or radio communications, significantly reduces stress levels and increases the operating efficiency of all personnel.

In addition, sufficient sleep cycles in the rest areas

1) increases the immune system’s ability to fight disease,

2) sustains keen perception ability, and

3) preserves higher mental abilities and motor skills.

In essence, an alert, combat-ready Soldier is restored.

Finally, nuisance noise common to the Garrison community potentially interferes with hearing warning sirens or emergency signals, potentially jeopardizing the safety of all installation personnel.

e. The essential elements of the Fort Campbell Hearing Program are listed below with general details provided in DA Pam 40-501, chapters 4-10 and FM 4-02.17, Preventive Medicine Services, Appendix C.

(4) Ensures applicable 85 dBA and 140 dBP noise contours are established and advises the unit Commander or supervisor where to locate hazard signs.


b. Industrial hygiene technicians or personnel trained in the use of noise measurement equipment-

(1) Will perform noise surveys as required. Guidance for performing noise surveys is provided in USACHPPM TG 181. Details for survey equipment and calibration guidelines are outlined in DA Pam 40-501, para 4-2.

(2) Noise surveys will be completed and documented using the DOEHRS-HC DD Form 2214 and/or DD form 2214C to identify hazardous noise survey results. Reports will be distributed and maintained IAW DA Pam 40-501, para 4-5.


c. Military and DOD civilian personnel may request a noise survey any time potentially noise-hazardous equipment is purchased or following any change in operations. In addition, previous noise survey records for specific locations can be requested. Record and survey requests can be directed to the IHPM.


d. The unit Commander or supervisor ensures that danger\caution signs and decals are posted at entrances to, on the periphery of, and on noise-hazardous equipment and vehicles in accordance with the Safety Color Code Markings, Signs and Tags Information Guide. In addition, 29 CFR 1910.95 must be posted in all industrial, noise-hazardous areas.

(1) Signs and decals may be obtained from the Department of Public Works.

(2) Sign requests must be submitted in memorandum format. Memorandums must include a description of the sign, specify the number of signs requested, the intended use of the sign(s), the building number for the sign, a point of contact with phone numbers for request, and be signed by either a unit First Sergeant or Company Commander.


8. Engineering controls


a. The most desirable hearing conservation measure is reducing noise levels at their source and eliminating harmful health effects. Implementation is generally feasible, if technologically and operationally practicable and


CAM Regulation 40-5 􀁹 31 January 2008
Page 8


cost effective. Procuring new equipment, vehicles or facilities offers the ideal opportunity to implement noise controls. The objective is to review all acoustic specification before purchase to ensure, if possible, a steady-state level less than 85 dBA at all personnel work locations during normal operations.


b. Control measures for existing equipment and facilities to reduce steady-state noise levels below 85 dBA and impulse noise levels below 140 dBP, should be employed to the maximum extent possible. In some instances, the implementation of engineering controls requires funding which is rank ordered on the installation hazard abatement plan per AR 385-10 and TB MED 503. In other instances, simple maintenance of the equipment, vehicles, or facilities will eliminate or control the hazard. Details for effective maintenance noise-control measures can be found in DA Pam 40-501, para 5-2.


c. An industrial hygienist from the Preventive Medicine Service can be consulted for engineering control recommendations and follow-up measures.


9. Hearing Protection Devices (HPDs)


a. All personnel working within or visiting potentially noise-hazardous areas must have hearing protectors withthem at all times. Military personnel will wear the earplug case containing preformed or hand-formed earplugs as a standard part of the uniform, either on the Soldier’s front right belt loop of the ACU trousers, the Soldier’s top right equipment loop of the flak vest, or the left arm pocket of the nomex flight suit.


b. Hearing protection devices (HPDs) consist of earplugs, noise muffs, ear canal caps, noise-attenuating helmets, or a combination of these. A list of approved hearing protection devices for government purchase can be found in Appendix E, which includes an example of a typical HPD purchase for a military unit. Personnel may select the type of protector desired, unless the selection is medically contraindicated or inappropriate for a particular noise-hazardous environment. In-depth descriptions and maintenance recommendations of approved HPDs can be found in DA Pam 40-501, paras 6-3 and 6-5.


c. HPDs are issued at no charge to all military personnel and to all DoD civilians working in potentially noise-hazardous areas. An earplug carrying case must also be provided at no charge with each set of preformed earplugs. This case can also be used for hand-formed earplugs. HPDs are considered required personal protective equipment for military deployments.


d. Fittings & Annual Integrity Checks. Organic unit assets that are CAOHC certified hearing technicians are qualified to complete fittings and integrity checks. Units without certified technicians may request support from the HCPM or the Hearing Conservation Clinic at 956-0305.


e. Requisition. Division unit HCOs must requisition HPDs through their Brigade Medical Supply Officers (BMSOs) using appropriate national stock numbers (Appendix E). Non-Division unit HCOs must requisition HPDs through the Department of Logistics at Blanchfield ACH by creating an account for Class VIII supply orders.


f. Requirements. Civilians and military personnel must wear appropriate hearing protection when working with or around equipment, tactical vehicles or weapons that produce hazardous levels of noise. Definitions of hazardous noise are listed below. Examples of steady-state and impulse noise levels produced by common military equipment are included in Appendix C.

(1) Steady-state noise levels of >85 dBA (regardless of duration) – requires single hearing protection.

(2) Steady-state noise levels of >103 dBA (regardless of duration) – requires double protection (i.e.; earplugs and helmets or earplugs and noise muffs).

(3) Steady-state noise exposure > 108 dBA – exposure is not permitted.

(4) Impulse noise levels of >140 dBP – requires single hearing protection.

(5) Impulse noise levels >165 dBP, but less than or equal to curve Z per MIL-STD 1474D, requirement four, figure 4-1, personnel must wear earplugs in combination with noise muffs or a noise-attenuating helmet.

(6) Impulse noise levels greater than curve Z, The Surgeon General must approve exposure.

(7) Combat scenarios and HPDs. In combat, Soldiers should wear hearing protectors, especially when firing weapons or riding in tactical vehicles or aircraft. Hearing protectors improve readiness and prevent permanent or temporary threshold shifts which impair the ability to communicate and to detect and localize quiet or low level combat sounds.

( Combat scenarios and communication requirements. In combat, Soldiers should be fit with nonlinear HPDs(i.e.; combat arms earplugs) or communication enhancement systems when impairment to hearing is detrimental to mission requirements (i.e., dismounted infantry operations).


10. Monitoring audiometry and hearing readiness


a. Monitoring audiometry detects changes in an individual's hearing sensitivity. This information identifies individuals who are highly susceptible to noise-induced hearing loss, allows for early identification of and


CAM Regulation 40-5 􀁹 31 January 2008
Page 9


intervention for hearing loss, and evaluates the effectiveness of the hearing conservation program. Hearing Readiness (HR) specifically focuses on ensuring Soldiers have the required physical capabilities, personal protective equipment (i.e., HPDs) and medical equipment that are needed to deploy. The main component of HR is monitoring audiometry. All hearing evaluations are to be completed on the DOEHRS-HC audiometer with results recorded on DD forms 2215 (Reference Audiogram) and 2216 (Hearing Conservation Data).


b. DoD Civilians. Reference audiograms for new civilian personnel with a potential for hazardous noise exposure must be performed as soon as possible, but not later than 30 days after initial exposure. Civilians will receive hearing tests administered by the Occupational Health clinic of Blanchfield ACH upon referral to the HCP.Hearing tests can be scheduled by contacting (270) 956-0202.


c. ALL noise-exposed and/or ototoxically exposed civilian personnel must receive reference, 90-day, annual, and termination audiograms. Follow-up hearing tests, 1 and 2, must also be provided, if required. Deaf civilians working in noise-hazardous areas must have reference and termination audiograms.


d. Termination audiograms must be conducted as part of out-processing or when a worker is going to stop working in a designated noise-hazardous area.


e. Soldiers. ALL Soldiers, regardless of potential noise exposure, must receive reference, pre-/post-deployment, and termination audiograms. Audiograms are required every 12 months, or within 6 months of (re)deployments.


f. Deployable Status. In order to be deployable, Soldiers must maintain a Hearing Readiness Classification (HRC) of Class 1 or Class 2. Appendix F provides the four basic HRC categories with definitions. To meet hearing readiness requirements, HCOs may schedule unit Soldiers for their DOEHRS-certified hearing tests by contacting their Battalion ESO or the LHC Hearing Conservation section at 956-0305.


g. Recordkeeping. Soldiers and DoD civilians will be provided with a copy of all hearing test results for their medical record. All DOEHRS-HC data will be forwarded to the DOEHRS-Data Repository, maintained at Aberdeen Proving Grounds, on a daily basis.


h. MEDPROS. The Medical Protection System (MEDPROS) HR module is used to track and monitor individual and unit level HR. DD2215 and 2216 audiograms are stored in the DOEHRS-DR and are used to calculate the HR status for MEDPROS. The DOEHRS-DR feeds the MEDPROS system on a weekly basis. HCOs can obtain unit Hearing Readiness (HR) reports through the MEDPROS Hearing Readiness Reporting Options function. Soldiers and HCOs can obtain copies of test results through personal Army Knowledge Online (AKO) accounts and through the MEDPROS Web Data Entry portal.

In summary:

(1) Soldiers with an HRC of Class 1 or 2 are deployable.

(2) Soldiers with an HRC of Class 3A-C are non-deployable and require a referral to an audiologist for the completion of a diagnostic evaluation, profile and/or MMRB (required for H3 profiles).

(3) Soldiers with an HRC of Class 3D-E are non-deployable and require either a hearing aid fitting and/or a 6 month supply of batteries for issued hearing aid(s).

(4) Soldiers with an HRC of Class 4A require an annual DD2215/16 hearing evaluation. A Class 4B indicates a significant threshold shift (STS) was detected on the annual hearing evaluation and requires a follow-up with the hearing conservation section technicians within 30 days.


i. The Installation HCPM will ensure installation test equipment, test methods, clinical services, diagnosis, medical and MEDPROS coding, referrals and notification processes (including OSHA reportable hearing losses) are in compliance with DA Pam 40-501, para 7-3 through 7-7 and FM 4-02.17 Appendix C, para C-9 through C-10.


11. Health education

The HCO or designee must ensure hearing conservation health education at least annually to ALL military and noise-exposed civilian personnel. Instruction requirements and educational materials are detailed in DA Pam 40- 501, paras 8-1 and 8-2. Unit HCOs are required to track annual unit requirements, coordinate instruction blocks with HCPM by contacting 956-0305, and maintain documentation for completion of course (i.e., sign-in rosters). HCOs may also obtain educational resources for briefings from the HCPM.


12. Enforcement


a. Command Emphasis. The unit commander or supervisor of personnel working in noise-hazardous areas must endorse the installation commander’s command emphasis letter explaining the importance of the HCP, the Fort Campbell HCP regulation, and the wearing of the earplug carrying case as part of the ACU, flak vest and/or the nomex flight suit.


b. Compliance Measures.

(1) Military and civilian supervisors of noise-hazardous areas must enforce the mandatory use of hearing protectors and take disciplinary action (i.e.; counseling statements) as appropriate for non-compliance.


CAM Regulation 40-5 􀁹 31 January 2008
Page 10


Commanders must enable unit safety officers and HCOs to bring units into compliance with the Air Assault and Fort Campbell Hearing Program.

(2) The HCPM will conduct unannounced inspections of noise-hazardous areas (including motor-pools, ranges, etc.) to ensure compliance with both HCP and HPD requirement and report inspection results through command channels as appropriate.

(3) The IHPM will inspect noise-hazardous areas to ensure compliance with HCP and HPD requirements during both announced and unannounced surveys.


13. Program evaluation

The HCP will be evaluated using both external and internal reports IAW DA Pam 40-501, paras 10-2 and 10-3. Program effectiveness, quality assurance, and compliance indicators will be forwarded to the Installation Medical Authority on a regular basis as required.


14. Operational Hearing Services (OHS)


a. The primary objective of operational hearing services is to enhance Soldier survivability. Hearing is a critical sense that directly affects mission success. Activities in garrison are geared towards preserving the ability to hear in a deployed, combat environment to enable the Soldier to detect the enemy and communicate effectively in noise. Garrison OHS includes communication enhancement/protection devices, hearing loss prevention tactics and noise surveillance/abatement strategies.


b. Communication Enhancement/Protection Devices (CEPDs). CEPDs are systems with active filters that protect hearing in the combat environment while enhancing the ability to hear on radios and among dismounted team members during missions.

(1) Contact the HCPM for information regarding CEPD use and procurement.

(2) Commanders must ensure their units are provided the opportunity to train with CEPDs and understand the use and importance of these devices in maintaining effective communication and situational awareness. Upon procurement, it is recommended that CEPDs are distributed on hand receipts (DA Form 2062) for accountability due to expense of individual systems.


c. Noise Surveillance and Abatement.

For guidance regarding suspected hazardous noise levels, refer to section 7 of this document for standard procedures.

For nuisance noise abatement, contact the HCPM for training and assistance.

Field environments, including TOCs, rest areas and motor pools, will be assessed with strategies for effective abatement outlined in verbal and written reports. HCOs will be trained in abatement during required operational and hearing readiness training courses and are responsible for implementing recommendations.

Nuisance noise is not normally recognized, addressed or limited, but its effects (stress, fatigue) can be devastating on the Soldier, the unit, and the mission.

(1) Ideal Noise Levels. Ideal noise levels for the field environment that allows for maximum efficiency:

(a) TOCs and common areas – noise levels not exceeding 55 dBA SPL, preserve the ability to communicate comfortably at distances up to 15 feet.

(b) Sleep Areas – steady-state noise levels of <40 dBA allow for sufficient sleep cycles.

In noisy environments, however, ‘maskers’ or broadband noise (such as a fan) may be required to eliminate the negative effects of relatively low-level intrusive noise (i.e., intermittent field radio communications).

The impact of intrusive noise varies (i.e.; intermittent landings of rotary and fixed-wing aircraft or tactical vehicles entering/leaving the compound). The sound level will depend on the engine type and distance from the source.

For example, a UH-60 helicopter will produce up to 90 dBA of intrusive noise inside a sleeping tent located 150 yards from the landing pad. This level of intrusive noise can be expected to awaken approximately 40% of tent occupants.

The use of disposable foam earplugs is the best remedy for situations involving regular intrusive noise.

(2) Basic Abatement Strategies. Basic strategies for nuisance noise abatement in the field are as follows:

(a) Move generators away from tents and use air conditioner extension hoses whenever feasible. The Inverse square law predicts that doubling the distance from a sound source decreases intensity levels by 6 dB.

(b) Place generators behind natural berms or enclose three sides of generators with sand bags, leaving room for proper ventilation. Point vented side of generator (normally the loudest side of equipment) away from tents.

(c) Design the TOC layout for maximum efficiency (i.e.; provide briefing areas away from radios). Determine which strategies work in the field environment before deployment.

(d) Provide foam earplugs for sleep tents to reduce effects of intrusive noise and ensure maximum ability to achieve REM sleep for Soldiers.


CAM Regulation 40-5 􀁹 31 January 2008
Page 11


15. Garrison nuisance noise

Nuisance noise produced by vehicles (i.e., excessive engine noise or stereo volume levels) and in post housing must be kept to a minimum to avoid interference with the perception of warning sounds or emergency vehicle signals. Nuisance noise is a citable offense in accordance with local ordinances. Command policy states that a radio detectable at distances of > 20 feet from the vehicle is excessive with violators subject to appropriate disciplinary action.


16. Hearing Conservation Clinic


a. Hearing Conservation is an individual and organizational responsibility. All commanders are encouraged to utilize the resources of the HCPM and the Hearing Conservation Clinic of LaPointe Health Clinic for the development and maintenance of their unit hearing conservation program.


b. Additional operational hearing conservation services, including preparatory assistance for the Hearing Conservation portion of the CIP, range and worksite consultations, custom hearing protection services, and hearing conservation certification workshops are available to installation units.


c. Contact the Hearing Conservation Clinic at (270) 956-0305 for more information and/or assistance.

Terms and Abbreviations

Terms:

Audiogram – A written representation of human hearing. Audiograms may be written in graph or serial format.

• Serial – Uses numbers in a table to depict thresholds. The forms used to record hearing thresholds for hearing conservation are serial audiograms.
DD2215 Reference audiogram, also called a baseline audiogram
DD2216 Periodic, Annual, Pre-/Post-deployment, 90-Day, Follow-up, Termination or Other audiograms
• Graph - Uses a graph to depict threshold.

Decibel - unit of measurement for sound, abbreviated dB.

Frequency - is perceived by the listener as pitch. The unit of measure for frequency is Hertz (Hz). Humans can detect pitches ranging from 10-10,000 Hz.

Hazardous noise area- is any working area in which workers are likely to be exposed to sound (noise) levels greater than 85 dBA, steady-state noise, or greater than 140 dBP, impulse noise.

Intensity- is perceived by the listener as loudness. Intensity is measured in decibels (dB). Decibels are normally referenced to a scale, such as dBA or dBHTL. The A scale is used for measuring noise, the HTL scale is used for measuring individual hearing ability. The term SIL indicates the speech interference level of background noise.

Noise Dose- is the ratio, expressed in percent, of the severity of a noise environment to the severity of exposure to 85 dBA for an 8-hour workday. A noise dose of 100% equals 85 dBA.

Occupational Safety and Health Association Reportable Hearing Loss (OSAHRHL) – Hearing loss is OSHA reportable when BOTH of the following occur:

- An STS occurs (an average 10 dB or greater change for thresholds averaged at 2, 3, and 4 KHz in either ear from the current baseline audiogram)
- Hearing thresholds for the current audiogram show an average of 25 dB or greater at 2, 3, and 4 KHz from audiometric zero for the shifted ear.

Risk Assessment Code (RAC)- is an expression of risk that combines the elements of health hazard severity and mishap probability. RAC’s are expressed in Arabic numbers. RAC’s rank order the hazards with lower number demanding more immediate attention.

Threshold- Represents the softest sound level a listener can detect about 50% of the time the sound is presented. Human hearing is measured with an audiometer. The unit of measure for human hearing is dB (HTL) (Hearing Threshold Level). Audiometers usually measure hearing from 0 to 110 dial. 0 dB does not mean the absence of sound it represents a reference of the softest sound level the human hearing mechanism can detect.

Time-weighted Average (TWA)- is the measure of a worker’s average noise exposure over the duration of the workday, expressed as DOSE%, or dBA; a measure of employee’s workday noise environment.

Ranges of Hearing
• -10 - 25 dB HTL Normal hearing
• 26 - 40 dB HTL Mild hearing loss
• 41 - 65 dB HTL Moderate hearing loss
• 66 - 90 dB HTL Severe hearing loss
• 90 + dB HTL Profound hearing loss

Section C-3

CHARACTERISTICS OF INDIVIDUAL EQUIPMENT NOISE


The following paragraphs summarize additional noise exposure considerations for common Army equipment:

a. Trucks and High Mobility Multi-wheeled Vehicles (HMMWV).

Noise levels increase with increasing speed and, for the HMMWV, with increasing load.

The levels are below 85 dBA at low to medium speeds and can be over 100 dBA at top speed for some models.

When driven mostly at low speeds with short periods at moderate or high speed trucks and HMMWVs are not hazardous.

They can be hearing hazards to unprotected Soldiers if operated for long time periods at high speed.


b. Bradley Fighting Vehicle (BFV) and derivatives.

The major noise source is the drive train, particularly the action of the track links as they round over the sprockets, idlers and wheels.

For this reason, high noise levels (101 to 115 dBA) occur when the vehicle is in motion.

The crew wears the combat vehicle crewman's (CVC) helmet which has integral hearing protectors. A CVC with active noise reduction (ANR) providing added noise protection is available on newer models.

The passengers (infantry squad) must rely on their own hearing protectors such as earplugs. These are less effective than the CVC with ANR.

For training, the exposure time in moving carriers is restricted depending on the hearing protectors worn and the speed of the vehicle.

The severest restriction is on exposure of passengers wearing the less effective earplugs.


c. M113 Armored Personnel Carrier and derivative vehicles.

Among the loudest of Army equipment. Noise sources and hearing protection are similar to the BFV.

Levels are very high when moving.


d. Abrams Tank and derivative vehicle (Wolverine and Grizzly).

(1) Steady noise levels range from 96 to 117 dBA when moving. The crew wears the CVC helmet which has integral hearing protectors.

(2) On the tank, impulse noise levels at exterior commander and loader positions are above or just below the limit of hearing protector effectiveness for training depending on caliber (105 or 120 mm), cartridge model, and tube-elevation.

The drivers hatch should be closed at all times when firing the main gun.

Training with crew heads above the hatch plane is not permitted per the user manuals for certain defined conditions.

These restrictions are not applicable to battle situations.


e. Helicopters.

In flight, helicopter crews wear the helicopter crew helmets which have integral hearing protectors.

Passengers must rely on their own hearing protectors such as earplugs or ones supplied by the air operations.

Training restrictions on exposure time apply, as discussed for the BFV.


f. Generators.

Diesel powered generators form the Tactical Quiet Generator (TQG) series are quiet at the operator panel and other close-in areas if the covers are in place.

Older generators have been loud with levels above 100 dBA at the panel and above 85 dBA up to several meters away.

High levels are generated by TQG if the covers are removed.


g. Impulse noise from weapons.

All firearms produce impulse noise levels requiring hearing protection at crew
positions for training.

Some produce levels under certain conditions, which exceed the safe training limit for crews wearing hearing protectors.

(1) Small arms- rifles pistols, machine guns, and 40 mm grenades.

- Noise levels at gunner positions are low to moderate.

- The hazard can be serious because of the large number of rounds that can be fired by the individual shooter.

- Noise levels are higher in front and to the side of the muzzle than to the rear. For small arms levels at about 5 feet to the side can be higher than at the shooter position.

- Except very near the muzzle, all levels are within the mitigation capability of hearing protectors.



CAM Regulation 40-5 􀁹 31 January 2008

(2) Mortars.

- Noise levels range from low to very high because of the wide variation in charge increments and head locations. The requirement to load the cartridge through the muzzle places the head close to the muzzle, which is the source of the impulse.

- For the top charge on the large ground mount mortars, a safe noise level for training occurs only at 2 m from the muzzle, no higher than 0.9 m above ground.

- Some mortars include a funnel-shaped blast-attenuating device on the muzzle.

(3) Howitzers without fighting compartments.

- For the 155 mm towed and 8-inch self-propelled howitzers the levels are medium to high depending on the charge increment, but are below the training exposure limit for protected Soldiers.

(4) Howitzers with fighting compartments.

- For the 155 mm self propelled howitzers the walls of the fighting compartment tend to attenuate the peak levels but the reverberation within the compartment aggravate the noise exposure.

- For some higher charges the front, top, and side hatches should be closed during training fire.


(5) Tanks.

- The levels above the turret hatches can be very high for some cartridges and at some tube elevations.

- For these, training fire with crew heads above the hatch plane is not recommended.

- Levels below the hatch plane, even with the hatch open, are lower.

(6) Rocket launcher vehicles. Impulse noise in the MLRS, Avenger, and FOG-M launchers are low to medium.

Appendix F

HEARING READINESS CLASSIFICATION SYSTEM


CLASS I Soldier’s unaided hearing is within H-1 standards for both ears. No corrective action is required. (Standards are described in AR 40-501).


CLASS II Soldier’s unaided hearing is within H-2 or H-3 standards. Soldier has a current hearing profile assigned (H-2 or H-3), and a completed MOS/Medical Retention Board (MMRB) (H-3) with no active middle ear disease or medical pathology in the ear. If A Soldier wears hearing aids, he must have hearing aids appropriate for hearing loss and a six month supply of batteries. No corrective action is required.


CLASS III Soldiers who do meet hearing readiness standards: Soldier’s unaided hearing is within H-2 or H-3 standards and no current hearing profile assigned. Comprehensive audiologic examination is required to establish profile and/or need for hearing aids.


CLASS IV Soldiers who do not have a DOEHRS-HC audiogram in their medical record within one year. Soldier requires a hearing examination. This includes Soldiers without a reference baseline audiogram (DD Form 2215) or whose last periodic audiogram (DD Form 2216) is greater than one year old. Hearing readiness classification is unknown.


Table Note: Soldiers in Class 1 and Class 2 will be considered fully ready. Soldiers in Class 3 or Class 4 are deficient. Soldiers in Class 3 or 4 at the time of medical record screening will immediately be reclassified in MEDPROS after obtaining corrective hearing/hearing aid services.

Here's a link that might be of assistance in your claim. I haven't read it too closely, but it seemed as if there were some interesting possibilities in it. I have not transferred the actual document since I think there might be copyright protections and I try to never infringe on those.

Anything for Air Force?

These were the only documents I could find. I hunted a long time for even these. Some aircraft stuff is mentioned within some of these documents, but I don't know if they pertain to you.

If you find something from the Air Force, please let me know. I will be glad to add it, just couldn't find additional information.

sorry.
