# Hearing Standards Compliance

Federal hearing standards under § 391.41(b)(11) require driver to first perceive a forced whisper at 5 feet, with or without use of a hearing aid. Drivers not meeting this may apply for the FMCSA Hearing Exemption Program.

## Federal hearing baseline
- Forced whisper test: perceive at 5 feet in better ear, or
- Audiometric test: average hearing loss in better ear not greater than 40 dB at 500, 1000, and 2000 Hz, with or without hearing aid

## Hearing Exemption Program
For drivers who don't meet the standard:
- Application to FMCSA
- Medical history + audiologist evaluation
- Documentation of safe driving with current hearing status
- Annual renewal

## Hearing aid considerations
- Many drivers use hearing aids to pass the test
- Hearing aid must be in good working order at time of exam
- Recommend backup aid in case of failure on the road
- Battery condition matters

## Common driver concerns
- "What if my hearing aid dies during a trip?" → carrier should require backup aid
- "Do I need to be tested every year?" → not unless cert was issued for less than 24 months
- "What if I get hearing aids between exams?" → no need to redo exam; document new aid at next visit

## Compass tracking
Compass medical module tracks:
- Hearing aid documentation (if applicable)
- Hearing exemption status (FMCSA-issued)
- Next renewal/exam due

## CFR citations
- **49 CFR § 391.41(b)(11)**
- **FMCSA Hearing Exemption Program**

## How Compass surfaces this
This skill is searchable in Compass Ask and runs against the carrier's actual fleet data when invoked from the relevant tracker. Read-only; no actions taken without explicit user approval.
