Comprehensive 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. This test usually takes about a half hour.


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 regarding the status of the patient’s middle ear function.

Pediatric Audiology

A pediatric audiology evaluation for young children can vary depending on the hearing problem and the age of the child. 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 typically conducted with toddlers. The child wears headphones and is conditioned to respond to sounds utilizing a game like technique.

Otoacoustic Emission Testing

Otoacoustic emissions are diagnostic test used to help the audiologist determine the cause of the hearing problem. In this test the patient does not need to do anything except be quiet and still. The otoacoustic emissions test lasts only a short time and is quite comfortable.

Professional Hearing Aid Services

Dr. O’Bell’s goal is to make the process of obtaining hearing aids as understandable and enjoyable as possible.  She has designed a step-by-step process to help the patient

  • Understand the hearing loss
  • Select the most appropriate hearing aids
  • Learn to use and care for the hearing aids

Each patient’s unique needs – degree of hearing loss, manual dexterity, visual acuity, lifestyle, and budget – are incorporated in every evaluation.

Tinnitus Evaluations

Patients suffering with tinnitus (“ringing in the ears”) can benefit from a tinnitus evaluation. We perform several diagnostic tests and utilize self-assessment surveys to determine the cause of the tinnitus and its psychological impact. Tests are performed to determine if the cause of the tinnitus is related to middle ear or inner ear problems as well as possible auditory nerve abnormalities. The frequency or pitch and volume of the tinnitus assessed to determine the optimum management option.
