Overview
VA hearing evaluations use specific testing methods. Everyday difficulty remains useful context, but the numeric evaluation is based primarily on authorized pure-tone and speech-discrimination results.
What VA measures
Hearing impairment is evaluated through the tables in §§ 4.85 and 4.86 using controlled speech-discrimination and pure-tone threshold results, with special provisions for certain exceptional patterns.
Authorized pure-tone thresholds
Maryland CNC speech-discrimination results
Exceptional patterns of hearing impairment
Results for each ear
Evidence that may be useful
- Current authorized audiogram
- Service audiograms and threshold shifts
- Noise-exposure history
- Audiology treatment and hearing-aid records
- Statement describing functional communication effects
Helpful documentation habits
- Retain complete audiograms, not only a summary
- Identify whether speech testing used Maryland CNC
- Describe real-world communication problems
- List occupational and recreational noise exposure accurately
Common preparation gaps
- Using an online hearing test as rating evidence
- Assuming hearing aids determine the percentage
- Submitting graphs without readable numeric results
