Diagnostic Audiological Evaluations

ACL Hearing and Balance Inc. provides comprehensive audiological evaluations to determine the type and degree of hearing loss. The evaluations can include pure tone testing, speech audiometry and Acoustic Immittance testing. Your physician will be provided with a written report summarizing the test result.

Comprehensive Hearing Evaluations include

  • Pure tone thresholds
  • Speech Audiometry
  • Middle ear Assessment
  • Otoacoustic Emissions Testing

More than 24 million Americans have some type of hearing problem. Hearing difficulties are often unrecognized by the person involved. The first step in the treatment of a hearing problem is a hearing evaluation by an audiologist. A comprehensive hearing evaluation by a licensed and certified audiologist will help determine the nature of the hearing loss. After that has been identified the most appropriate treatment strategy can be determined.

Types of Hearing Loss and Common Causes

Conductive Hearing Loss

A conductive hearing loss is the result of the disruption of sound transmission through the outer and middle ear. People with conductivce hearing losses often report that sounds are not loud enough.

Common Causes
  • Outer and middle ear infections
  • Perforated ear drum
  • Small or missing ear canals
  • Poorly formed middle ear bones

Sensorineural Hearing Loss

A sensorineural hearing loss is the result of damage to the inner ear. This is the portion of the ear connected to the hearing nerve that transmits sound to the brain. People with sensorineural hearing losses report that sounds are not loud enough and that their speech understanding is poor.

Common Causes
  • Family history
  • Aging
  • Exposure to loud sounds
  • Certain types of prescription drugs
  • Diseases of the inner ear

Central Hearing Loss or Auditory Processing Disorders

The person with an auditory processing disorder has a problem processing sound in the brain or the central nervous system. The individual with an Auditory Processing Disorder (CAPD) has normal hearing but will often have complaints similar to those with a hearing loss.

Causes of CAPD are not fully understood at this time

Treatment Strategies

  • Listening devices to help improve the signal to noise ratio
  • Language therapy

What to Expect During an Evaluation

Prior to arriving at the appointment the parent/guardian should complete the case history form. This can be downloaded from ACL’s website. Upon arriving at the appointment, the audiologist and parent/guardian can then go over the case history to fill in any missing information. The child will then undergo a full audiological evaluation. This is to verify that no hearing loss is present. If no hearing loss is present, the AP evaluation will begin. Testing will include:

  • Auditory closure – ability to fill in missing pieces of information.
  • Auditory figure ground – the ability to understand speech in the presence of noise.
  • Binaural integration – the ability to listen to two conversations.
  • Binaural separation – the ability to block out one conversation and attend to another conversation going on at the same time.
  • Temporal patterning – the ability to remember and sequence information correctly.
  • Binaural interaction – the ability of the two ears to fuse information.
  • Auditory decoding – the ability to discriminate, sequence, remember, blend and take apart sounds within words.
