Twenty normal hearing young adults ingested 1.4ml alcohol per kg body weight over 60 minutes. Then the blood alcohol levels, breath alcohol levels were measured by Dupont ACA blood analyzer and DPA-2 breath analyzer. Also the thresholds and the amplitudes of the acoustic reflex were measured by impedance audiometer ZO-72, using 1.5sec., 500Hz., pure tone stimulation contralaterally in 13 persons, and ipsilaterally in 7 persons. First, the thresholds were decided and then the amplitudes were recorded after the stimulation by the sounds of 20dB more than those of before drinking alcohol. The results were as follows: 1) In 13 persons who the stimulation were given contralaterally, the amplitudes were decreased at the point of just finishing drinking. Four persons showed remarkable decrease, while five showed no significant change. 2) In 7 persons, who the stimulation were given ipsilaterally, the thresholds were increased at the points of just finishing drinking, 30 minutes later, 60 minutes later. No variability was found among them. 3) No significant relations were found not only between the blood alcohol levels and the changes of the thresholds, but also between the blood alcohol levels and the changes of the amplitudes. From the above mentioned, it was concluded that the acoustic reflex was depressed when people drink alcohol, and people will get morepossibilities of suffering from acute sensorineural healing loss if they are exposed to loud sounds while drinking, like in discos.
