Complete Audiological Evaluation
A Complete Audiological Evaluation (CAE) or hearing test is performed to determine if a hearing loss is present and, if so, to determine the type of hearing loss-sensorineural (inner ear or auditory nerve) or conductive (middle ear) as well as the severity of the hearing impairment exhibited. The evaluation also includes speech testing (Speech Reception Threshold and Speech Discrimination testing) to determine both the softest level of speech a patient can perceive as well as to assess the percentage of words a patient can perceive clearly. Before any testing is performed the Audiologist will visually inspect the ears with an Otoscope to rule out the presence of any wax, infection of the ear canal, or perforation of the eardrum.
Middle Ear (Impedance Audiometry) Testing
Testing of the middle ear (eardrum and bones or ossicles behind the eardrum) is performed to rule out an ear infection (fluid behind the eardrum), any perforation of the eardrum, or abnormal pressure behind the eardrum (eustachian tube dysfunction) which can occur due to flying, colds and/or sinus issues. Acoustic Reflex testing is performed to determine if the nerve pathways are intact that connect the middle ear muscles to the brainstem (the Reflex Arc). This is a very quick and painless procedure that helps to determine the type of hearing loss present and to screen for benign tumors of the auditory nerve pathways.
Distortion Product Otoacoustic Emissions (DPOAE’s) Testing
This test is performed for all infants, (as part of a global mandate to screen for hearing loss), as well as for adults to assess the function of the hair cells of the inner ear (at each frequency) to confirm the presence or absence of a hearing loss and to confirm hearing test findings.
The audiological evaluation is a good chance to establish a relationship with your Audiologist and to ask questions. We would like you to be clear and comfortable with any information you receive in order to be an active participant in finding hearing solutions that work best for you as well as your family and lifestyle.
Counseling on Test Results and Medical History
Comprehensive review of all test results will be performed by your Audiologist as well as counseling for recommendations and any medical follow up. It is recommended that a family member accompanies you to your appointment, if possible. Audiologists agree that hearing loss can be a family issue. It is helpful to have a supportive person present at the appointment to help to understand the information and recommendations.
