Acoustic reflex thresholds were measured for eighteen young adults (9 men and 9 women) at four different blood alcohol levels: 0.00%, ascending 0.10%, 0.15% (peak level), and descending 0.10%. Reflex-eliciting stimuli consisted of three narrow-band noises (300 to 600, 600 to 1200, and 1200 to 2400 Hz) and three broad band noises (white noise, recorded rock music, and recorded factory noise). Prealcohol reflex thresholds were found to be significantly more sensitive than all postalcohol reflex thresholds for all stimuli, and broad-band stimuli demonstrated greater threshold shifts than did narrow-band stimuli. Significant sex differences were not observed for any blood alcohol level. Between subject variability was high, with 10 subjects showing little or no reflex threshold change and the other 8 subjects showing dramatic threshold changes.
对18名年轻人（9名男性和9名女性）在四种不同血液酒精浓度水平下测量了听觉反射阈值：0.00%、上升至0.10%、0.15%（峰值水平）以及下降至0.10%。引发反射的刺激包括三种窄带噪声（300至600赫兹、600至1200赫兹以及1200至2400赫兹）和三种宽带噪声（白噪声、录制的摇滚音乐以及录制的工厂噪声）。发现所有刺激下的饮酒前反射阈值都显著比饮酒后反射阈值更敏感，并且宽带刺激比窄带刺激表现出更大的阈值变化。在任何血液酒精浓度水平下均未观察到显著的性别差异。个体间变异性较高，10名受试者的反射阈值变化很小或没有变化，而其他8名受试者的阈值变化显著。
