Pure Tone Audiometry
Pure-tone Audiometry is a behavioural test measure used to determine hearing sensitivity and is conducted in a soundproof room.The test is performed using headphones and the patient is asked to respond each time they hear a sound. Pure-tone thresholds indicate the softest sound audible to an individual at least 50% of the time. Hearing sensitivity is plotted on an audiogram, which is a graph displaying intensity as a function of frequency.
