SINGLE_GROUP
Additionally, in other outcome measures, participants will listen to pre-recorded stimuli that have the various frequency response curves applied. In this case, participants once again will be exposed to different hearing aid curves while simply listening via hearing aids and making preference selections. In the end, participants can be exposed to different hearing aid variations (i.e., interventions) simultaneously and also have the ability to go back and forth.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Participants with Hearing Loss
Individuals with hearing loss that meet the candidacy to wear hearing aids. All interventions are associated with the fitting of binaural hearing aids with various coupling methods. All participants will be assessed under all interventions.
Hearing Aid - Standard Curve
Our current hearing aids which will be programmed to our standard frequency response curve.
Hearing Aid - Variation #1
Hearing aids that will have the frequency response curve adjusted and fit to the participant's hearing loss.
Hearing Aid - Variation #2
Hearing aids that will have the frequency response curve adjusted and fit to the participant's hearing loss.
Hearing Aid - Variation #3
Hearing aids that will have the frequency response curve adjusted and fit to the participant's hearing loss.
Hearing Aid - Variation #4
Hearing aids that will have the frequency response curve adjusted and fit to the participant's hearing loss.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Health Outer ear
* no visible congenital or traumatic deformity of the outer ear
* Symmetrical hearing loss - no air-bone gap greater than 10 dB at all 500, 1000, 2000, and 4000 Hz.
