Abstract
  • Real ear measurements are being used to predict and validate hearing aid fittings. The purpose of this study was to investigate the relationship between the hearing aid response as measured by real ear measurements to pure tone hearing thresholds and ear canal resonance. In order to test this hypothesis clinically, data were collected from 13 satisfied hearing aid wearers of 24 custom canal hearing aids. Results revealed that pure tone thresholds and canal resonance together is not a significant predictor of hearing aid response as measured by real ear measurements, at 500, 1000 and 2000 Hz. But at 3000 and 4000 Hz, ear canal resonance is a significant addition to the fitting model of pure tones. Because of the limited sample it can be stated that canal resonance appears to be a significant predictor of hearing aid response as measured by real ear measurements at 3000 and 4000 Hz.
