In previous work, we reported significant differences in signal modification for mild versus strong signal processing in commercially available hearing aids. In this study, we extend this work to clinically prescribed hearing aid fittings based on best-practice guidelines. The goals of this project are to determine the range of cumulative signal modification in clinically-fit hearing aids across manufacturers and technology-levels, and the effects of listening conditions including signal-tonoise ratio (SNR) and presentation level on these signal modifications. Design: We identified a subset of hearing aids that were representative of a typical clinical setting. De-identified hearing aid fitting data were obtained from three audiology clinics for adult hearing-aid users with sensorineural hearing loss for a range of hearing sensitivities. Matching laboratory hearing aids were programmed with the de-identified fitting data.
