Audiologic Evaluations

Why a Audiologic Hearing Evaluation is Important

The audiologic evaluation is important to have as soon as you find that you or your child may suffer from hearing loss. It is the first step in finding out exactly what hearing loss may be present and how to deal with it to improve quality of life. For many, it is often the first step on a life-long journey to in improving your quality of life.

Audiologic evaluations give your audiologist important information about your hearing loss to help determine the best course of action for treatment. Some types of hearing loss can be treated medically or surgically, so it's important that these types of hearing loss be ruled out before hearing aids are considered.

Once it's determined that you could benefit from hearing aids, the evaluation let's your audiologist know which hearing aid will be appropriate for your needs.

What Can I Expect During a Audiologic Hearing Evaluation?

It is recommended that you bring a family member with you to the evaluation appointment. Most audiologists agree that hearing loss is a family issue. It helps to have another supportive person at the appointment to help you remember and be clear on all information and recommendations. This person's voice will also be used to test the volume and clarity of your hearing aid.

What Tests Will Be Done?

These purpose of these tests are to determine things such as the degree of hearing damage, what type of hearing damage is present, the health of the ear canal, and the health of the middle ear. The audiologist will also want to determine if hearing change is conductive (middle or outer ear) or sensorineural (inner ear, in the central processing center of the brain).


Otoscopy is a clinical procedure used to examine structures of the ear, particularly the external auditory canal, tympanic membrane, and middle ear. Clinicians use the process during routine wellness physical exams and the evaluation of specific ear complaints.


Tympanometry refers to a test that helps in the evaluation of the proper functioning of the middle ear. The middle ear is positioned behind the eardrum, also known as the tympanic membrane.‌ The test seeks to establish the condition and movement of the tympanic membrane as it responds to changes in pressure

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. It also checks how loud words or speech needs to be in order for you to hear it.

Word discrimination, sometimes called Speech recognition is performed to see how clearly you can understand and distinguish different words when you hear them spoken.

Pure-tone 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 conduction testing. A different type of headphone is used during bone conduction testing, as it evaluates the function of the inner ear and hearing nerve.
