  • Ages 18-100
  • All Genders

Study Summary

The present study will confirm the clinical benefit of 2 different released hearing aid models for speech understanding (in noise). Participants with mild to severe hearing impairment will be fit binaurally with Unitron hearing aids and will perform a standardized speech discrimination test in noise with and without hearing aids.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Adults (18+ years) with hearing impairment (N2 - N6 hearing loss).

  • Healthy outer ear.

  • Symmetrical hearing loss.

  • Ability to answer questions and repeat sentences.

  • Willingness to wear different style of hearing aids.

  • Willingness to wear a binaural fitting.

  • Willingness to wear closed domes.

  • Willingness to adhere to COVID protocols including correct mask use, completingscreening for each visit

Exclusion

  • History of active drainage from the ear in the previous 90 days.

  • Abnormal appearance of the eardrum and ear canal.

Study Description

Each participant will be asked to wear a set of BTE and RIC hearing aids and complete the Hearing in Noise Test (HINT) aided and unaided. The investigators will be assessing their speech intelligibility in noise for each condition during the same appointment to determine the SNR50 (the Signal-to-Noise ratio necessary for a participant to recognize the speech material correctly 50 percent of the time).
