The purpose of this study was to investigate the relationship between live and recorded determinations of most comfortable loudness levels (MCL's) and to determine if a relationship existed between MCL's, tolerance levels (TL's), and acoustic reflex thresholds so that further research might be conducted regarding the use of acoustic impedance measures in hearing aid fitting.Thirty normal hearing female subjects were tested in this investigation. MCL's using live and recorded stimuli, TL's, and contralateral and ipsilateral acoustic reflex thresholds were obtained for each subject. Correlation coefficients were computed to determine if a relationship existed between any of the measurements.It was concluded that live voice stimuli yielded highly equivalent results to recorded stimuli in finding MCL's. Acoustic reflex thresholds were found to be poor predictors of MCL's and TL's. Before acoustic reflex measurements can be used in hearing aid fitting procedures, further research is warranted.
