Masking techniques were applied to a group of 10 subjects with normal hearing, to investigate the influence of masking on the latencies of brain stem auditory evoked potentials. The levels of sufficient masking and overmasking were determined. Central masking, as established in a psychophysiological manner, cannot be clearly demonstrated by auditory brain stem evoked potentials. When masking the untested ear, the alterations in the response are small and this can be ignored in clinical practice if masking of the untested ear is necessary.
对一组10名听力正常的受试者应用了掩蔽技术，以研究掩蔽对脑干听觉诱发电位潜伏期的影响。确定了充分掩蔽和过度掩蔽的水平。以心理生理学方式确定的中枢掩蔽，无法通过听觉脑干诱发电位清楚地显示出来。当掩蔽未测试耳时，反应的变化很小，如果在临床实践中需要掩蔽未测试耳，这一点可以忽略不计。
