Pure Tone Audiometry

Description

Pure tone audiometry (PTA) is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss.

It is a scientific procedure by which a hearing aid is selected for a hearing impaired person, using an eclectic method comprising both subjective and objective procedures. A hearing aid is a medical device, and selecting the appropriate device for the person depends on different criteria such as degree and nature of hearing loss.
