Other Hearing Tests

In addition to the audiogram, Hearing Specialists of Texas offers an array of audiology service.  Our goal is simple: we want to help you hear better.

Tympanometry and Reflex Testing

Tympanometry and Reflex Testing measures how well the ear drum and middle ear system are working. A puff of air is delivered into the ear and the amount the eardrum moves in response to change in air pressure is recorded. The results are used to determine the presence of middle-ear fluid, a perforation of the ear drum, and other middle ear disorders. Testing takes about 5 – 10 minutes.

Otoacoustic Emissions Testing (OAE)

Otoacoustic Emissions Testing (OAE) is an evaluation of cochlear function. A normal cochlea will emit an echo in the presence of sound. OAE testing is performed by placing an earphone in the patient’s ear canal and introducing various sounds.   A highly sensitive microphone measures the presence, absence, and degree of the response from the cochlea. OAE results allow the audiologist to determine if the cochlea is functioning normally and can take 10 – 20 minutes. OAE testing is performed on newborns prior to discharge from the hospital, which is mandated by the state of Texas.

Pediatric Hearing Assessment

Good hearing is essential for a child to develop speech, language, and learning skills. It is important that hearing loss is identified as early as possible (in the first few months of life) to insure adequate speech and language development. Hearing in Infants and babies can and should be assessed as early as possible. If you are concerned about your baby’s hearing contact our Audiology Department at 281-897-6066.

Auditory Brainstem Response Testing (ABR)

ABR is used as an objective test for determining hearing abilities. It is useful in newborns and infants who cannot reliably perform behavioral testing. Four electrodes are attached to the scalp, earphones are placed in the ears, and clicks or tones are presented. The ABR provides information about the function of the auditory pathway to the level of the brainstem.   A computer records the response to the clicks and tones, providing an estimate of hearing sensitivity. The ABR takes approximately one hour.

Electronystagmography (ENG)

ENG testing assesses balance and equilibrium. Eye movement, monitored by electrodes or goggles, is recorded in response to changes in position and other external stimuli. ENG testing takes about one hour.

Visual Response Audiometry (VRA)

VRA is used for children beginning at just a few months of age to about three years. The child is conditioned to turn toward an animated toy or lights in response to sound. VRA allows the Audiologist to determine the child’s hearing levels.
