Comprehensive Audiological Assessments

An audiological assessment can quantify and qualify hearing in terms of the degree of hearing loss, the type of hearing loss, and the configuration of the hearing loss. The audiological evaluation consists of a battery of tests, each providing specific information about hearing.

Audiogram

An audiogram is a graph that helps illustrate usable hearing and the amount of hearing loss for each ear.
Each sound has a certain pitch or frequency. The frequency is measured by the number of waves or cycles that a sound makes in a single second. The scale used to designate cycles per second is called Hertz (Hz). Loudness of a sound, or intensity, is measured in units called decibels (dB).
An audiologist presents tones one frequency at a time. The softest tone a person can hear at each frequency is marked on the audiogram. This is called a hearing threshold.

Tympanometry 

Tympanometry is an objective test which examines the middle ear, the mobility of the eardrum, and the conductive bones by which sound is transmitted. A small probe tip is placed in the ear canal while the patient sits quietly listening to a tone and feeling a slight variation in air pressure.

Otoacoustic Emissions (OAE)

OAE's are sounds originating in the cochlea, specifically from the outer hair cells, that propagate through the middle ear and then into the ear canal where they are measured with a sensitive microphone system.

Auditory Brainstem Response (ABR)

ABR is a neurological test of auditory function that measures the timing of the brainstem's responses to click or tone stimuli, traveling from the outer, middle, and inner ear structures and through and including the brainstem.

Dizziness/Vertigo/Balance

As part of their scope of practice, Audiologists are trained to understand the vestibular system, which is made up of the cochlea and the labyrinth of the inner ear. The vestibular system is what controls your balance and spatial orientation. Our audiologist works with physicians and therapists to evaluate and treat balance conditions, such as Vertigo, associated with problems of the vestibular system.

ENG/VNG

Electronystagmography/Videonystagmography (ENG/VNG) consists of tests used to assess the function of the peripheral and central vestibular systems. Electrodes (ENG) or video goggles (VNG) are used to measure the movements of the eyes to detect involuntary movement known as nystagmus. This movement is the only physical sign uniquely linked to the vestibular system and the ENG/VNG test battery is a valuable tool in this assessment.
