Pure tone audiometry is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss. Thus, providing the basis for diagnosis and management.  This is a subjective, behavioral measurement of hearing threshold, as it relies on patient response to pure tone stimuli. Therefore, Pure Tone Audiometry is used on adults and children old enough to cooperate with the test procedure

Speech Recognition Testing determines how well speech is understood and helps detect problems that might exist beyond the hearing nerve. It also gives insight as to how well hearing aids can help.

Immittance Testing evaluates middle ear function by assessing how well the eardrum and middle ear bones move and is very useful in determining the location of a problem.

• Otoacoustic emission (OAE) is a sound which is generated from within the inner ear.  Numerous studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health.

Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system.  The test is performed by attaching electrodes around the nose and eyes measuring the movements of the eye.  ENG provides an objective assessment of the oculomotor and vestibular systems. A newer standard for the recording is the use of infrared video systems which allow for a more detailed observation and analysis of these eye movements, called Video Nystagmography (VNG).

Auditory Brainstem Response (ABR) Testing is an objective neurological function test used to estimate hearing levels in difficult-to-test patients. It measures how well sound is transmitted from the hearing nerve to the brainstem.  ABR audiometry is a safe and painless test of auditory pathway and brainstem function in response to auditory or (click) stimuli

Auditory Processing Disorders (APD) Testing is designed for children that exhibit learning difficulties, memory issues, problems following directions and behaviors which interfere with auditory comprehension. It determines whether there is a processing breakdown along the path as auditory signals pass from the ear to the brain. We also offer  coping and rehabilitative strategies. hearing aid services diagnostic services • Evaluation and Treatment of Tinnitus determines whether ringing or buzzing is caused by trauma to the inner ear. We offer prevention advice and treatments.

Newborn Hearing Screenings support our involvement with the Universal newborn hearing program at the local hospitals. Those who are referred from the screen must go on to more detailed audiological assessment (usually before 3 months of age) which will include ABR and OAE tests, including with stimuli at different frequencies if necessary. Most babies sleep through these tests. We also participate in Florida state early intervention program for fitting of hearing aids on newly identified hearing impaired infants.

Hearing Instrument Evaluations are performed to ensure that hearing instruments, which are designed to amplify sound, are functioning properly. A properly functioning instrument collects sounds from the environment, amplifies them, and directs an amplified signal into the user’s ear.
