Study Summary
Directional microphone hearing aids have been shown to provide benefit for individuals with hearing loss in a number of laboratory experiments. However, few studies have investigated the real-world, subject-reported benefit from these hearing aids, and even fewer have examined directional hearing aid benefit across varying degrees of hearing loss. This study will summarize data from a three-year, multi-faceted study of directional hearing aid benefit. Ninety four subjects were divided into three hearing loss groups (normal-to-moderate, mild-to-moderately-severe, and moderate-to-profound). These subjects were then fit with experimental hearing aids set to either directional or omnidirectional mode to determine if significant differences were present in hearing aid outcomes (both subjective and objective). Both subject and experimenter were blinded to the hearing aid settings. Following one month of use in each experimental setting, subjects completed: probe microphone measurements, speech understanding in noise testing, use questionnaires, subjective benefit scales, and satisfaction scales. At the conclusion of the study, subjects rated their preferences for the experimental settings in quiet, noise and overall. Both objective measures, as well as subjective data, were analyzed across hearing aid and hearing loss conditions.
