Adult Hearing Evaluations:
Adult hearing evaluations include a complete, non-invasive evaluation of your hearing using state-of-the-art equipment. This is a thorough assessment to determine the exact type and degree of hearing loss, and how well or poorly you understand speech. It includes a complete case history, as well as visual inspection of the ear canal and eardrum. The audiologist may use the following tests:
- Pure Tone Audiometry: This test measures your hearing ability at different pitches and at different volumes by raising your hand or pressing a button when a sound is detected. These results are recorded on a graph which is called an audiogram.
- Word Recognition Testing: For this testing, an audiologist will test your ability to hear, understand and respond to speech by your repetition of simple words.
- Basic Immitance Test Battery: These tests measure how the eardrum responds to sound. They provide information about the status of the middle ear, such as the detection of fluid in the middle ear or any perforation of the eardrum.
- Otoacoustic Emission Testing (OAE): OAE is an electroacoustic test which measures the function of the outer hair cells (integrity of the cochlea). A small insert earphone is placed in the ear canal through which sounds are played and responses are measured. The presence or absence of OAEs is important to help identify hearing loss.
Additional testing Services:
- Auditory Processing Disorder (APD): An auditory processing disorder is the inability or impaired ability to recognize or comprehend information by hearing even though a person has normal intelligence and normal hearing sensitivity. The auditory processing test battery consists of a series of auditory tests designed to measure processes such as phonemic decoding, dichotic listening, binaural integration, auditory closure and temporal patterning.
