Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The long-term goal of this research program is to develop methods to predict both the benefit and the satisfaction that hearing-impaired patients will derive from auditory amplification in daily life. This proposal has three primary objectives: (1) To determine the influence of extra-audiological variables, such as personality attributes and expectations, on the subjective outcomes of hearing aid fittings, (2) To establish a scientific basis for selection, administration, and interpretation of self-report measures of hearing aid fitting outcome, (3) To resolve the long-standing debate about the efficacy of using clinically measured loudness perception data in hearing aid prescriptions.
