1. Pure-tone audiometry could be described as a behavioral test used to measure hearing sensitivity.
2. The essence of PTA is to determine the threshold level for hearing in a patient. In addition it helps the audiologist at DENOC to identify the degree (mild, moderate, severe, profound) of hearing loss, type (conductive, sensorineural, mixed) of hearing loss and its configuration (unilateral or bilateral). Thus, providing the basis for diagnosis and management.
3. The result of Hearing analysis is plotted on an audiogram, which is a graph displaying intensity as a function of frequency.
