记录70名正常听力受试者在60dB、70dB和80dB时的脑干诱发电位。从第2年到第8年，每十年有10名受试者（男5名，女5名）。最小的研究对象只有14岁，最大的79岁。研究了潜伏期随着年龄的增长而增加的可能性。结果表明，实际上并没有这种增加。另一方面，有非常有力的证据表明，女性的潜伏期比男性短。此外，在年龄较大的受试者中，振幅减小。计算潜伏期的置信限。这些可能有助于确定特定延迟是否超出正常范围。
Brainstem evoked potentials in response to clicks at 60dB, 70dB and 80dB were recorded from a group of 70 normally hearing subjects. There were 10 subjects (5 male, 5 female) for each of the decades from the second to the eighth. The youngest subject was 14 years, the oldest 79 years. The possibility of there being increased latencies as a function of age was examined. The results indicated that there was, for practical purposes, no such increase. On the other hand there was very strong evidence that in females latenceis are shorter than in males. In addition, amplitudes were reduced in the case of older subjects. Condifidence limits for latency were calculated. These may be helpful in deciding whether or not a particular latency is outside the normal range.
