Hearing (Audiometric) Evaluations

Hearing evaluations include several specialized tests. They are used to help assess whether a patient has normal hearing or has experienced hearing loss. By using a battery of tests, a health care professional (audiologist) can determine the type and degree of hearing loss. Tests include:

  • pure and warbled tone audiometry – to determine hearing loss at specific frequencies
  • bone conduction audiometry
  • speech reception thresholds
  • determination of speech discrimination – used to determine a patient’s ability to understand speech

Impedance Audiometry

This test measures the movement and integrity of the eardrum (tympanic membrane). It also can determine the absence or presence of fluid in the middle ear. It helps measure pressures in the middle ear for air pressure in the environment. It is also used to determine if the muscles and ear reflexes are performing properly.


This procedure is used together with Impedance Audiometry and is an examination used to test the condition of the middle ear and mobility of the eardrum (tympanic membrane) as well as the conduction bones, by creating variations of air pressure in the ear canal.

Electronystagmography (ENG)

ENG is a group of tests that are used to determine the cause of vertigo and/or dizziness. The tests measure the motion of the eyes to one another. Additional tests measure how the organs affecting balance are functioning. Used together with a physical examination and hearing tests, ENG can help to identify the cause of a patient’s balance problems.

Live Speech Mapping

Live Speech Mapping is a fitting process that incorporates the use of probe microphones with spoken words. This helps patients and family members readily experience and understand how hearing aids that are properly fitted and adjusted can help patients who are candidates for them.

Hearing Aid Evaluation and Dispensing

In many cases, audiologists who evaluate a patient for hearing loss will make recommendations for a hearing aid best suited to meet the needs of a patient. Similarly, many audiologists also make fitting impressions for earmolds as well as minor adjustments to the hearing aid.

Assistive Listening Devices (ALDs)

ALDs are used when hearing aids are not sufficient to fully rectify a patient’s hearing problems. ALDs include devices for television, telephone, and FM and infrared amplification for classrooms or theaters.

Ear Molds

For swimmers, those in high-noise environments, and for those in the music profession, custom earmolds can protect from further hearing loss.

LACE (Listening and Communication Enhancement) Training

LACE training, available on CDs, provides instruction for developing better listening habits for those finding themselves in difficult listening situations.
