The Pure Tone Audiometry (PTA) test is the key hearing test at the Rehabilitation Center. PTA test is used to identify hearing threshold levels of an individual, enabling determination of the degree, type, and configuration of a hearing loss.
PTA provides ear-specific thresholds and uses frequency-specific pure tones to give place-specific responses so that the configuration of a hearing loss can be identified. As PTA uses both air and bone conduction audiometry, the type of loss can also be identified via the air-bone gap.
