A Comparison of Hearing Aid Noise Programs on Speech Intelligibility

Hearing impaired participants will be fit with study devices which will have three different hearing aid programs. Speech intelligibility will be measured using validated tests for each of the three hearing aid programs. The order of the hearing aid programs will be randomized across participants and each participant will be blinded as to the programs being tested.

Program 1 is the current default in the commercially available devices. Programs 2 and 3 are being tested against the current default.
