Hearing Diagnostic Services

We offer a full range of diagnostic services to help detect hearing impairment and loss in both adults and children. Testing helps determine the type and severity of hearing loss. Several types of testing are offered:

  • Pure Tone Audiometry determines the threshold at which you can hear by evaluating the softest sounds you can detect.

  • Word Recognition Testing involves repetition of single-syllable, phonetically balanced words. The scores for each ear provide information that will help determine the need for more testing or referral. It is also used to see if amplification may be helpful for some patients and to evaluate the success of hearing aid fittings.

  • Testing of Middle Ear Function evaluates the middle ear function by measuring its response to air pressure variations and acoustic signals.
  • Otoacoustic Emission Testing (OAE) evaluates cochlear or inner ear function in infants, children or adults by measuring the ear’s response to sound.
  • Auditory Processing Testing diagnoses and provides recommendations to take care of problems in the processing or use of sounds.
  • Auditory Brain Stem Response Testing (ABR) This is an objective test that can estimate hearing sensitivity in difficult-to-test patients such as infants. ABR can also assess neural integrity of the auditory pathway to aid in differential diagnosis.

Hearing Aids and Hearing Protection

A variety of models and types of digital hearing aids as well as custom hearing protection and swim plugs are available. Your Mercy audiologist will work with you to determine which hearing aid is right for you. Your audiologist can fit and program cochlear implants and osseointegrated devices.

A hearing aid is an electronic device that is worn either in or behind the ear. It increases the volume of sounds that someone with hearing loss has difficulty hearing on their own. Hearing aids help you hear in quiet and in noisy environments. They can also help lessen the feeling of fatigue from straining to hear.
