What hearing services do you offer?

Hearing screenings, diagnostic audiometric testing, hearing aid fittings, and follow-up care.

Do you work with veterans and VA benefits?

Yes. We help eligible veterans access hearing care and hearing aids through applicable VA programs.

How often should hearing be tested?

Adults should have a baseline test and periodic re-checks, especially with noise exposure or noticeable changes in hearing.

How do I book an appointment?

Call (424) 204-2382 or email info@mobileaudiologyservice.com to schedule.

Do you need a sound booth for a valid hearing test?

No. Boothless audiometry with circumaural attenuation and continuous ambient-noise monitoring delivers ANSI S3.6-compliant testing in an ordinary room, proving its own test conditions.

What does an OSHA hearing-conservation program require?

Once noise reaches an 8-hour average of 85 dBA: a baseline audiogram, annual audiograms compared for standard threshold shift, hearing protection, and training — on calibrated audiometers.

Is occupational hearing-loss testing being reviewed?

Yes. The Department of Labor opened a comment period in June 2026 on hearing-loss testing methods, weighing the audiogram against objective tests, with comments due October 22, 2026.

DOL Opens a Comment Window on How Occupational Hearing Loss Is Tested

On June 23, 2026 the Department of Labor's Office of Workers' Compensation Programs opened a public comment period on the quality standards used to evaluate occupational hearing loss under the Longshore and Harbor Workers' Compensation Act. The core question is whether the pure-tone audiogram should remain the primary standard or whether objective tests — auditory brainstem response, auditory steady-state response, and otoacoustic emissions — should play a larger role. Comments are due October 22, 2026.

The agency is inviting input from audiologists, otolaryngologists, employers, employees, and insurers on the comparative reliability of these methods and on the criteria used to judge hearing impairment. However the rulemaking lands, it signals that measurement quality is back at the center of the conversation.

For now the operating standard is unchanged: OSHA's 1910.95 hearing-conservation program with baseline and annual audiograms once exposures reach 85 dBA, on audiometers calibrated to ANSI S3.6.

The Federal Register notice is explicit that it proposes nothing yet: it is a request for information, and the Department says the responses will inform whether updates to the existing quality standards should be considered at all. That is worth reading carefully before anyone re-tools a program. Employers, insurers, audiologists, otolaryngologists and medical associations are all invited to comment on the comparative reliability and validity of audiograms against ABR, ASSR and otoacoustic emissions, on how those tests are currently administered, and on the criteria used to judge impairment. Comments go through the Federal eRulemaking Portal at regulations.gov.

Nothing about the day-to-day obligation changes in the meantime. Under 29 CFR 1910.95 a hearing conservation program is triggered at an eight-hour time-weighted average of 85 dBA; a baseline audiogram is due within six months of first exposure at or above that action level, or within a year where a mobile audiometric testing unit is used; testing is annual thereafter, at no cost to the employee; and audiometric records are retained for the duration of employment while noise-exposure measurements are kept at least two years. The mobile-unit allowance is not a loophole — it is written into the standard.

Boothless Audiometry Comes of Age

For decades a defensible hearing test meant a sound booth. Portable audiometry has closed much of that gap: devices with circumaural attenuation and continuous ambient-noise monitoring can deliver ANSI-compliant pure-tone testing in an ordinary room, verifying in real time that background levels stay within limits and flagging any test where they do not.

That capability is what makes true on-site hearing conservation possible — testing a rotating workforce at the worksite instead of busing crews to a clinic. The trade is not accuracy for convenience; it is a booth for an instrument that proves its own test conditions, provided calibration and technique stay disciplined.

The reason this matters is scale. NIOSH puts the number of U.S. workers exposed to hazardous noise at about 27 million a year, with roughly 22 million more exposed to ototoxic chemicals, and estimates that about one in nine people in the working population already has hearing difficulty. Occupational hearing loss is permanent, and it is one of the most common work-related illnesses in the country — yet it is also, in NIOSH's own framing, nearly always preventable. Prevention at that scale does not happen if the test requires a booth and a day off.

Boothless does not mean unregulated. ANSI/ASA S3.1 sets maximum permissible ambient noise levels for audiometric test spaces across octave and one-third-octave bands from 125 Hz to 8000 Hz, and a compliant portable system monitors against those limits continuously rather than assuming a quiet room stays quiet. When a forklift passes and the low-frequency bands spike, the software flags the affected thresholds instead of quietly recording them. That single behaviour — refusing to certify a test the conditions did not support — is what makes on-site results defensible.

Field Notes

Field Notes: Calibrating to ANSI S3.6 in a Trailer

A hearing test taken in a trailer is only as good as the instrument behind it, so calibration is the first task of the day, not an afterthought. Biological and electroacoustic checks confirm the audiometer is reading true before the first worker sits down, and the ambient-noise monitor stays on throughout.

The habit that keeps mobile results defensible is documentation: calibration state, test conditions, and result tied to each person, every time. Treat each deployment like a small regulated lab and a result taken on-site stands up exactly like one from a fixed clinic.

Who performs the test is also part of the standard. OSHA permits audiometric testing by a licensed or certified audiologist, an otolaryngologist or other physician, or by a technician certified by the Council for Accreditation in Occupational Hearing Conservation — or one who has otherwise demonstrated competence in administering audiometry, obtaining valid audiograms, and properly using, maintaining and checking the calibration and function of the audiometers in use. Note how much of that sentence is about the equipment: competence with the instrument is written into the qualification itself.

The rest is habit. Daily biological and listening checks before the first worker sits down. Transducers kept with the audiometer they were calibrated against. Periodic electroacoustic calibration on a documented cycle, with the certificate on file rather than in someone's van. Ambient monitoring running for the whole session. Each result tied to the right person, the right date and the right test conditions. Treat a mobile deployment like a small regulated laboratory and its audiograms hold up in a comparison years later — which, in occupational hearing conservation, is the only test that matters.
