Diagnostic Audiologic Evaluation

The evaluation is done to determine if a hearing loss is present, and if so, to detail the type and severity of the hearing loss. It also may provide insight in to the cause of the hearing loss as well as provide guidance for us in making appropriate treatment recommendations.

What Tests Will Be Done?

The specific tests done during the evaluation will depend on the patient's age, and what is known already about their hearing status. These various tests will determine the degree of hearing loss, the type of hearing loss, and the conditions of the ear canal and middle ear. We will also determine if the hearing loss is conductive (middle or outer ear problem) or sensorineural (inner ear problem or central processing difficulty of the brain).

A diagnostic audiologic evaluation includes pure-tone testing, bone-conduction testing, and speech testing.

Pure-tone Air and Bone Conduction Testing

Pure-tone air conduction testing determines the quietest tones that a person can hear at different frequencies, both low and high. Bone conduction testing is similar to pure-tone air conduction testing. A different type of headphone is used during bone conduction testing, and the results help us determine if the hearing loss is originating from the outer/middle ear or from the inner ear.

Speech Testing

A speech reception threshold (SRT) test is often used with older children and adults to confirm the results of a pure-tone test. This test determines the lowest level at which the patient can recognize words or speech stimuli.

We may also perform otoscopy (examining the ear canal) and tympanometry (test of the middle ear) to determine the health of the ear canal and the middle ear.

Specialized tests exist for infants and young children, as well as children and adults with developmental and cognitive impairments. These more-specialized tests allow us to test the auditory system when the patient is not able to actively participate in the tests or evaluation.

Other tests may include:

  • Auditory brainstem response (ABR) and auditory steady-state response (ASSR) testing
  • Otoacoustic emissions (OAE) screening
