Pure Tone
Audiometry
Pure tone audiometry (PTA) standard behavioural test of an individual’s hearing sensitivity. Test results are recorded on a graph called an Audiogram. Audiometry provides information about hearing levels across the frequencies used in speech. It gives an inference with regard to how well, or how poorly, an individual can hear specific frequencies and for a comparison of one ear to the other. It also allows a clinician to make inferences with regard to diagnosis and possible management options.
