This study evaluated the effects of probe frequency and gender on the click-rate-induced facilitation of the acoustic reflex thresholds (ARTs). ARTs were measured by delivering clicks at the repetition rates of 60, 120, 180, 240 and 300/sec. The probe tones were 226, 678 and 1000 Hz. Rate-induced facilitation (RIF) was calculated for each subject, for each of the probe tones, by subtracting the minimum ART from the maximum ART. The mixed MANOVA on the RIF revealed no significant main effects or interactions for gender or probe tone frequency. However, paired comparisons revealed that the RIF values obtained from male subjects with the 1000 Hz probe tones were significantly lower than those obtained from the female subjects with all the probe tone frequencies. The results suggest that RIF can be studied with higher probe tones, but gender differences need to be considered if the probe tone is 1000 Hz.
本研究评估了探测频率和性别对点击速率诱导的听觉反射阈值（ART）易化作用的影响。通过以60、120、180、240和300次/秒的重复速率发出咔嗒声来测量ART。探测音为226、678和1000赫兹。通过从最大ART中减去最小ART，为每个受试者、每种探测音计算速率诱导易化（RIF）。对RIF进行的混合多变量方差分析显示，性别或探测音频率不存在显著的主效应或交互作用。然而，配对比较显示，从使用1000赫兹探测音的男性受试者获得的RIF值显著低于从使用所有探测音频率的女性受试者获得的RIF值。结果表明，可以使用更高的探测音来研究RIF，但如果探测音为1000赫兹，则需要考虑性别差异。
