Hearing Evaluation

To evaluate the cause of hearing problems in children and adults a variety of tests are used. For the basic test the patient responds to auditory stimuli by raising their hand or pressing a button; different pitches and loudness will be used to determine the patient's hearing levels. Additional diagnostic tests include otoacoustic omissions and tympanometry with acoustic reflexes.

Sound Retraining Therapy

Tinnitus is a sensation of sounds heard inside the head, commonly described as a high pitch ringing. We are selected as a Lenire provider. Schedule your evaluation appointment now.

Hyperacusis is a disorder in loudness perception. Patients suffering from hyperacusis may appear overly sensitive to a range of sounds, finding many noises unbearable and painfully loud.

Misophonia is defined as a strong dislike of certain sounds and an abnormally strong reaction to them such as anger or even fear. The specific sounds that cause the reaction are unique to each individual.

The goal of the sound retraining program for tinnitus is to evaluate and help the patient habituate to their tinnitus so it doesn’t interfere with their life. The sound retraining program for the hyperacusis or misophonia patient will help tolerate annoying sounds and learn to cope.

Patient Testimonials

Central auditory processing disorder (CAPD) is also known as Auditory processing disorder (APD). People with CAPD usually have normal hearing. However, parents and/or other people often notice that their child(ren) have difficulty in understanding verbally presented information or require extra time to process what people are saying.

    Common symptoms:
  • Struggles with following directions
  • Struggles with listening and following conversations, especially when there is background noise
  • Difficulty differentiating between sounds in words
  • Requires repetition or rephrasing of what people said
  • Difficulty understanding or can become overwhelmed when others speak quickly
  • Takes longer to respond to others
  • Poor musical and singing skills
  • Difficulty paying attention
  • Easily distracted

While the symptoms of CAPD have some overlap with symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD), we have clear diagnostic indicators that will allow us to accurately diagnose CAPD. When you make an appointment for a CAPD exam, we will perform a comprehensive hearing evaluation followed by the CAPD evaluation. Once CAPD is diagnosed, we will discuss treatment options. The appointment will start at 9:15am and be done around 2pm.
