A basic hearing test called Pure Tone Audiometry (PTA) is performed to determine the faintest tones a person can hear at different frequencies, usually from low to high pitches. The test involves the patient wearing headphones to listen to a series of beeps or tones and signaling when they detect a sound.

 The findings are displayed on an audiogram, which aids audiologists in determining the kind and severity of hearing loss and enables them to suggest suitable interventions or assistive technology.
