Impact of Enlarged Adenoids Affect Your Hearing

Enlarged adenoids located at the back of the throat have the potential to negatively impact the middle ear’s ability to adequately stimulate the inner ear’s cochlea.

Enlarged Adenoids?

Cheri Moore has been helping children and adults improve the brain’s ability to respond to intervention while minimizing negative behavioral responses.


It is an honor to work with Cheri Moore on her journey with auditory integration therapy.  She has shown a consistent desire to go above and beyond in every aspect of her practice and training.  Cheri’s quest for greater understanding and her thirst for knowledge are demonstrated daily.  It is a pleasure to work with a professional who is so eager to learn and apply new information to help her clients reach their best possible outcomes.

Temporary Hearing Loss Associated with Ear Infections Increase Risks for Negatively Affecting Brain Development

The health of the hearing system is essential to promote brain development in children affecting brain development. Numerous studies found that disruption of the hearing system due to ear infections, especially during infancy and preschool years of brain development, negatively affected the development of speech, language, balance, and auditory processing skills.
(Casselbrant, Gravel, Margolis, Bellussi,, Dhooge, & Downs, 2002; Vernon- Feagans & Proctor, 1994; Hasenstab in 1992; and Benasich & Tallal, 2002).

(Casselbrant, Gravel, Margolis, Bellussi, Dhooge, & Downs, 2002) (Klein, 2001, as cited in J. S. Stenton, 2003).

Negative Impact of Enlarged Adenoids

Haapaniemi (1995) found that participants with normal-sized to medium-sized adenoids experienced the behavioral characteristics below only 7% to 9.8% of the time while 25% (133 children) of 663 children, seven to 14 years of age, with enlarged adenoids experienced the following behavioral characteristics 14% to 30% of the time:

  • Open-mouth breathing
  • Snoring with first graders being the most affected age group
  • Chronic congestion (blocked nasal pathway) also called sinusitis or rhinitis
  • Decreased hearing by 1.1 to 4.2 decibels depending on size of enlarged adenoids
  • Eight times more likely to have experienced four or more ear infections

Statistically significant differences between the two control groups showing an increased risk for decreased sound energy reaching the cochlea:

  • Greater hearing loss during a common cold (.0003)
  • Abnormal color and position of ear drum (tympanic membrane .0001)
  • Lower pressure (60 to 70mm H2O) in the middle ear when compared to participants with typical-sized adenoids.

Enlarged Adenoids Contribute To Ear Infections

Under-activity occurs in the hearing system when there are ear infections, enlarged adenoids, or lack of strong sound stimulation along auditory neural pathways. 

Cheri Moore's Findings Resulted in Improved Responses to AIT and Vision Therapy

Cheri Moore's desire to improve clients' emotional response during auditory integration training resulted in the discovery of a high rate of co-existing visual processing difficulties with sound intolerance, with or without a hearing loss.  After some clients experienced increased visual processing difficulties during AIT, like chronic double vision, Cheri Moore collaborated with optometrists specializing in vision therapy to track client's progress.  Auditory-visual protocols have resulted in improved responses to auditory integration training and vision therapy.

FDA Statement On AIT

"Auditory Integration Training remediates impairments in auditory discrimination (sound sensitivity and auditory distortion) associated with Autism, Learning Disabilities, and related disorders - ADD, ADHD, CAPD (Central Auditory Processing Deficits), SPD (Sensory Processing Disorder), Dyslexia."
