Résumé : | Objective: The purpose of this study was to measure real-ear aided and saturated responses of SpeechEasy devices and compare responses while devices delivered altered auditory feedback (AAF) and non-altered feedback (NAF). Design: A repeated measures quasi-experimental design was employed. Study sample: Ten people fitted with completely-in-the-canal or open fit behind-the-ear devices participated. Probe microphone measures were obtained with speech, and 17 chirp stimuli presented at 75 dB and 85 dB SPL, respectively. Measurements were compared with devices delivering AAF (i.e. delayed and frequency shifted) versus NAF. Results: Maximum outputs were approximately 100105 dB SPL in the 20004000 Hz range. Statistically significant differences in device SPL output as a function of device setting (AAF vs. NAF) were found for seven chirp stimuli (p <.05 when levels were sampled at points that not temporally aligned with the output chirps but for speech stimulus .17 device varied across individuals and open fit devices dominated by ear canal resonance effects. conclusions: real-ear aided responses equivalent input delivered aaf naf. saturated however comparable between naf settings may be underestimated if delay is accounted for.> |
