摘要:
This study investigates the controversy regarding the influence of age on the acoustic reflex threshold for broadband noise, 500‐, 1000‐, 2000‐, and 4000‐Hz activators between Jergeretal. [Mono. Contemp. Audiol.1(1978)] and Jerger [J. Acoust. Soc. Am.66(1979)] on the one hand and Silman [J. Acoust. Soc. Am.66(1979)] and others on the other. The acoustic reflex thresholds for broadband noise, 500‐, 1000‐, 2000‐, and 4000‐Hz activators were evaluated under two measurement conditions. Seventy‐two normal‐hearing ears were drawn from 72 subjects ranging in age from 20–69 years. The results revealed that age was correlated with the acoustic reflex threshold for BBN activator but not for any of the tonal activators; the correlation was stronger under the 1‐dB than under the 5‐dB measurement condition. Also, the mean acoustic reflex thresholds for broadband noise activator were essentially similar to those reported by Jergeretal. (1978) but differed from those obtained in this study under the 1‐dB measurement condition.
