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 Jerger et al. [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 Jerger et al. (1978) but differed from those obtained in this study under the 1-dB measurement condition.
本研究调查了杰格尔等人[《单声道当代听力学》1 (1978)]与杰格尔[《美国声学学会杂志》66 (1979)] 一方面和西尔曼[《美国声学学会杂志》66 (1979)] 等人另一方面之间关于年龄对宽带噪声、500赫兹、1000赫兹、2000赫兹和4000赫兹刺激声的声反射阈值影响的争议。在两种测量条件下评估了宽带噪声、500赫兹、1000赫兹、2000赫兹和4000赫兹刺激声的声反射阈值。从72名年龄在20至69岁之间的受试者中选取了72只听力正常的耳朵。结果显示，年龄与宽带噪声刺激声的声反射阈值相关，但与任何音调刺激声的声反射阈值均无关；在1分贝测量条件下的相关性强于5分贝测量条件下的相关性。此外，宽带噪声刺激声的平均声反射阈值与杰格尔等人(1978年)报告的基本相似，但与本研究在1分贝测量条件下获得的结果不同。
