Use the overall percent hearing loss calculator!
Pure tone audiometry is the key hearing test used to identify hearing threshold levels of an individual. It is the gold standard test for determining the degree and type of a hearing loss.
The combined hearing loss calculation is based on the ANSI* standards, used for hearing impairment assessment and compensation purposes.
The calculater is used to estimate the sensorineural hearing loss.
* The American National Standard Institute (ANSI)A Pure Tone Average (PTA) refers to the average of hearing threshold levels at a set of specified frequencies: typically 500, 1000, 2000 and 4000 Hz. This value gives a snapshot of an individual's hearing level in each ear.
By entering your Pure tone audiometry results, this tool will calculate the overall percent hearing loss you have according to different equations.
