Occupational Hearing Loss Workers' Comp in California — Audiogram Evidence, Hearing Aids, and Rating

How do you prove loud work caused your hearing loss?

A hearing test plus your work history ties the loss to job noise. A neutral doctor reviews both and writes the deciding report.

First you take a hearing test, called an audiogram. It maps the sounds you can still hear. It also shows the ones that are gone. Steady job noise leaves a telltale mark. It usually takes the high tones first.

How loud is too loud? Steady noise above about 85 decibels can harm ears over a full shift. Think of a busy machine shop or an airport ramp. If you had to shout to be heard, your ears were at risk.

Then a doctor lines up that pattern with your work. Think back over your years on the floor. Loud presses, rivet guns, jet engines, forklifts, and power tools all count. If the insurer fights the cause, a neutral doctor steps in. You pick that doctor from a state panel of three names under Labor Code 4062.2. Each side strikes one name.

Get tested even if you are unsure. A simple audiogram is quick and painless. It gives you proof in writing. The sooner you have it, the stronger your claim. A hearing specialist is called an audiologist. Your claim doctor may send you to one. Bring any old hearing tests too. Army records, school tests, or past job screens can show the change over time.

When did your hearing injury legally happen?

A slow injury has no single date. The law sets it as the day you knew the loss was real and caused by work.

This date drives your deadlines, so it matters a lot. A slow injury is called cumulative trauma. It builds across many shifts and many years.

So when does the clock start? Labor Code 5412 sets your date of injury as the day two things meet. You feel the disability. You also learn that work caused it. Often that is the day a doctor first connects the dots for you.

Here is a common story. You work loud lines for 20 years. You retire and the ringing gets loud. A doctor runs a test and names the cause. That visit, not your first loud shift, can start your one-year clock. So do not assume it is too late.

From that date, you have firm windows to act. Miss them, and you can lose the claim. Here are the main ones.

You can file while still on the job. You do not have to quit first. Tell your employer in writing and keep a copy. A short note with the date protects you. Fear of payback is normal, but the law shields you for filing.

What does a hearing loss claim pay you?

It covers all your medical care, plus cash. You can get hearing aids, weekly checks while you heal, and a lump sum for lasting loss.

Your medical care is free to you. There is no copay and no bill. Labor Code 4600 makes the insurer pay for tests, ear doctors, and hearing aids. They must service and replace those aids too.

If your ears keep you off work, you get temporary checks. They run about two-thirds of your average weekly wage. Labor Code 4656 caps these at 104 weeks.

When your hearing settles, a doctor rates your permanent loss under Labor Code 4660.1. The higher the rating, the more weeks of pay you get. The ringing, called tinnitus, can lift that rating. Here is what common ratings are worth at the 2026 top rate.

There is more help if the loss is severe. If you cannot return to your old job, you may get a $6,000 voucher. It pays for retraining at a school. Very high ratings can also add a lifetime monthly pension. Your award can move up or down based on a job offer too. We make sure every part is counted.

Do not wait to start. Hearing loss claims rest on good records. The earlier we build yours, the better. We line up the testing and handle the paperwork. You focus on your health.

What if age caused some of your hearing loss?

You still get paid for the work share. The insurer can subtract only the loss truly caused by age, and they must prove it.

Hearing does fade with age. So the insurer may claim age caused part of your loss. Splitting the cause this way is called apportionment.

Labor Code 4663 lets them pay only for the work-caused share. But the burden is on them to prove the rest. A vague guess does not count. The doctor must back the split with real reasons.

This is where many workers get shortchanged. A strong medical report can push the work share higher. That puts more money back in your pocket. Do not take the first low offer without a review. Ask us to review the report before you accept anything.

Picture a press operator with bad loss. The insurer says half is just age. Your doctor reviews the noise logs and the test. The doctor ties 80 percent to the job. That swing can mean thousands more in your award. We do not let the insurer guess your future away.
