People who are hard of hearing can join the military, but only if their hearing loss falls within specific decibel limits set by the Department of Defense. Your hearing at 500, 1,000, and 2,000 Hz must average no worse than 25 dB, with no single frequency in that range exceeding 30 dB. At 3,000 Hz the limit is 35 dB; at 4,000 Hz it’s 45 dB. If your hearing falls outside those limits, a medical waiver is possible, though approval rates have ranged from roughly 8% to 62% depending on the branch.
The Hearing Thresholds You Have to Meet
DoD Instruction 6130.03, Volume 1, sets the hearing standards every applicant must clear. Your hearing is measured with an audiometer calibrated to American National Standards Institute specifications. A hearing level in either ear that exceeds any of the following is disqualifying:
- Average across 500, 1,000, and 2,000 Hz above 25 dB, or any single frequency in that range above 30 dB
- Above 35 dB at 3,000 Hz
- Above 45 dB at 4,000 Hz
There is no standard at 6,000 Hz, so hearing loss at that frequency alone won’t disqualify you.1Department of Defense (DoD). DoD Instruction 6130.03, Volume 1 – Medical Standards for Military Service: Appointment, Enlistment, or Induction Even mild loss that crosses one threshold at a single frequency triggers a disqualification, regardless of how well you hear at the others.
Hearing Aids and Cochlear Implants
If you currently use hearing aids or have a documented history of needing them, that alone disqualifies you from enlistment. The military tests unaided hearing because service members have to function in settings where hearing aids may be impractical or unavailable. A history of hearing aid use tells the DoD your natural hearing has already fallen below what it considers operationally reliable.1Department of Defense (DoD). DoD Instruction 6130.03, Volume 1 – Medical Standards for Military Service: Appointment, Enlistment, or Induction
Cochlear implants are also disqualifying. The regulation lists a history of any surgically implanted hearing device as a disqualifying condition.1Department of Defense (DoD). DoD Instruction 6130.03, Volume 1 – Medical Standards for Military Service: Appointment, Enlistment, or Induction Waivers in this category are extremely unlikely, because implanted devices are vulnerable to damage from blast exposure, water immersion, and the physical demands of training and combat.
What Happens at the MEPS Hearing Test
Every applicant takes a hearing test at a Military Entrance Processing Station as part of a broader medical evaluation that includes blood work, vision screening, and a physical. The hearing portion is a standard audiometric exam. You wear headphones in a controlled environment and press a button each time you hear a tone, no matter how faint. Tones play at 500, 1,000, 2,000, 3,000, and 4,000 Hz at varying volumes, in no predictable pattern.2U.S. Army. Processing and Screening (MEPS)
One practical note: loud noise exposure in the days before your test can temporarily shift your hearing thresholds. Skip concerts and loud earbud sessions for several days beforehand. A temporarily elevated threshold from a noisy weekend can produce a disqualification that doesn’t reflect your actual baseline.
Applying for a Waiver
Failing the hearing portion at MEPS doesn’t automatically end your enlistment. Each branch runs its own medical waiver process, and each branch’s waiver authority makes an independent, case-by-case decision based on the severity of your hearing loss, the documentation you provide, and current personnel needs.3Health.mil. Accessions and Medical Standards
A waiver request takes more than the MEPS audiogram. You’ll typically need a consultation from a licensed audiologist that includes speech reception thresholds and speech discrimination scores, plus a separate evaluation from an ear, nose, and throat specialist. If your hearing loss persists after any treatment or surgery and still exceeds the enlistment thresholds, a functional hearing test may also be required.4U.S. Navy.

Which Branch Gives You the Best Odds
Approval rates for hearing waivers differ enormously by branch. Research from the Walter Reed Army Institute of Research covering fiscal years 2016 through 2020 reported:
- Navy: 62.1%
- Air Force: 28.6%
- Army: 12.8%
- Marine Corps: 8.1%
The Navy approved hearing waivers at nearly eight times the rate of the Marine Corps during that period.5WRAIR. Accession Medical Standards Analysis and Research Activity Annual Report These are historical figures and can shift as branches update their policies, but they give you a realistic sense of your odds.
The Department of the Air Force recently broadened its waiver criteria for hearing loss. Under the updated policy, applicants with moderate hearing impairment in one ear can be considered for a waiver as long as the opposite ear meets the standard for mild hearing impairment. Approved applicants receive assignment limitation codes and are restricted from career fields where worsening the condition would create a safety risk.6Air Force.

How Your Hearing Affects the Jobs You Can Hold
Meeting the enlistment threshold or receiving a waiver gets you in the door. Your hearing level then determines which jobs you’re eligible for through the military’s PULHES physical profiling system, where the “H” stands for hearing:

The impact is real. Army aviation requires an H-1 or H-2 profile, so an applicant with an H-3 profile can still commission into the Army but is excluded from aviation roles. The Navy restricts certain specialties for applicants with hearing-related conditions. Each branch keeps its own list of jobs tied to specific hearing profiles, so the same hearing level might open more roles in one branch than another.
If You’re Already Serving
The standards for staying in are more forgiving than the standards for getting in. Accession rules under DoDI 6130.03, Volume 1, are built to screen out conditions before they become the military’s responsibility. Retention rules under Volume 2 ask a different question: does your hearing loss actually prevent you from doing your job?3Health.mil. Accessions and Medical Standards
Under the retention standard, hearing loss is incompatible with continued service only when it prevents safe performance of duty even with hearing aids or other assistive devices, persists despite appropriate treatment, and impairs the ability to carry out the duties of your rank and role.7Department of Defense (DoD). DoD Instruction 6130.03, Volume 2 – Medical Standards for Military Service: Retention Note the difference: active-duty members can use hearing aids and still be retained. Hearing aids disqualify you from enlisting, but they don’t automatically force you out once you’re in. Service members whose hearing drops to an H-3 profile may face a Medical Retention Board, which decides whether to retain, reclassify into a different job, or medically separate the individual.
