Hearing Assessment

A number of tests are available to discover the nature of a hearing difficulty and to help determine effective treatments. The tests include:

Pure Tone Audiometry (PTA)

Basic audiogram determines the patient’s hearing ability relative to normal adult hearing levels to determine the type and degree of hearing loss. This information is critical to determine if medical or surgical intervention is possible or if hearing aids may help.

Speech Descrimination Test

The range of audible sounds, not just the degree of hearing loss, can vary considerably from person to person. Unfortunately, when hearing is damaged it is usually not just the volume of sound that is softer. Often the quality of the sound is also distorted. The amount of distortion can be measured using speech discrimination tests.

A speech test, which requires the patient to hear specific single words and repeat them back at various testing speech levels, allows us to understand the functional hearing which can reflect to real-life performance.


Tympanometry assesses the operational status of the middle ear, which consists of the eardrum and three small bones that connect the eardrum to the inner ear. Middle-ear blockages or malfunctions often can be treated medically or surgically.
