PTA (Pure Tone Audiometry)
Pure Tone Audiometry (PTA) is an important examination of ears. This test is carried out to identify the hearing capacity of an individual that has been suffering from loss of hearing. After the test is completed the size and length of hearing loss can be judged.
Tympanometry is a very useful assessment of ears and their hearing capacities. Under this, the condition of the middle area of ear and the mobility of the eardrum is tested. This process is done through the route of ear canal. This particular test helps in making distinction between sensorineural and conductive hearing loss.
Speech threshold audometery is procedure used in the assessment of individual’s threshold of hearing for speech.
