Pure Tone Audiometry (PTA)
Pure Tone Audiometry (PTA) is to assess hearing level by demonstrating a specific response (such as hand-raising or button pushing) to an acoustic stimulus. It is appropriate for testing individuals from school-age through adulthood. Results define the nature and degree of hearing impairment.
Play Audiometry (PA)
This assessment is appropriate for testing children of 3 year old or above. Sometimes children are given a more play-like activity (Conditioned Play Audiometry) to indicate response.
Visual Reinforcement Audiometry (VRA)
This assessment is appropriate for testing children from 7 to 30 months of age. It assesses hearing sensitivity using conditioned responses to sound, i.e., head turning. This procedure can be used to determine threshold of hearing. Because signals are typically presented through a loudspeaker, thresholds obtained indicate hearing level of the 'better hearing ear' only.
Impedance Audiometry (IA)
This test assesses the status of the middle ear system to provide information about the status of the tympanic membrane and middle ear system.
Auditory Response Audiometry
This test is to assess auditory function from cochlea level up to the brainstem.
