Our Hearing Services

  1. Hearing Evaluations

    A hearing evaluation is performed while the patient is in a sound treated audio booth. The test includes three parts. Headphones or insert ear phones are placed on the ears for air conduction and speech understanding testing. A little black vibrating box is placed behind the ear for bone conduction testing. The patient is expected to press a button or raise a hand whenever a beep is heard for air and bone conduction testing. During speech understanding testing the patient is to repeat a list of words or sentences either in quiet or with noise in the background. This is a test that determines how well a person understands words and measures the ability of a person to process speech sounds in challenging environments. This test usually takes about a half hour. Follow this link on hearing evaluations for a more detailed explanation.

  2. Tympanometry

    This is the pressure test that determines how well the eardrum moves. A humming sound is heard and a small amount of pressure is felt in the ear. This test does not last long – about 10 seconds for each ear – but can give the audiologist valuable information on a graph called a tympanogram. For more information follow the link to tympanometry.

  3. Pediatric Audiology

    A pediatric audiology evaluation for young children can vary depending on the hearing problem that is described. An interview with the parents will help determine what will actually happen. Usually tympanometry is done if an ear infection is suspected. Air pressure is introduced into the ear to determine how well the eardrum moves. It takes about 5 to 10 seconds for each ear. Visual reinforcement audiometry is done in the audio booth, usually with the baby in a parent’s lap. The child’s responses to sounds from the loud speakers are measured. Play audiometry is done when a speech and language delay is suspected. The child wears headphones and tosses a block into a box whenever she/he hears a beep. Plan on the evaluation lasting a half hour. Follow the link for more details.

  4. Auditory Processing Evaluations

    Usually performed on school children who seem to have a hearing loss, but traditional testing indicates normal hearing. These children are easily distracted by extraneous noise that typically does not bother other children. The test, which is performed in the audio booth, includes a series of subtests and can last about an hour. For more detailed information click here.

  5. Electrophysiological evaluations including Auditory Brainstem Response and Otoacoustic Emissions

    Electrophysiological evaluations include otoacoustic emissions and auditory brainstem response testing. These are diagnostic tests used to help the audiologist and the referring physician determine the cause of the hearing problem. In both tests the patient does not need to do anything except be quiet and relax. The patient can even sleep for the auditory brainstem response test. Electrodes are placed on the ears and loud sounds are heard through an earphone. The otoacoustic emissions test lasts only a short time, so most patients are able to stay awake. Both tests are quite comfortable. More details can be found here.

  6. Professional Hearing Aid Service

    Dr. Holzhaeuser’s goal is to make the process of obtaining hearing aids as understandable and enjoyable as possible. He has designed a step-by-step process to help the patient understand the hearing loss select the most appropriate hearing aids, and learn to use and care for the hearing aids
