In a group of 30 adults with impaired hearing, objective thresholds defined with 40 Hz middle latency responses (MLR) were compared with subjective audiometric measures. Frequencies of 0.25, 0.5, and 1 kHz were studied. In order to guarantee a good frequency specificity, subjects presenting large high-frequency hearing loss were particularly chosen. The 40-Hz MLR thresholds were generally worse than the audiometric measures. The average difference was around 12 dB, but in about one-third of the cases it was between 20 and 30 dB. Although not perfect, 40-Hz MLR estimates on low frequencies can be very helpful and deserve further consideration, especially in children.
在一组30名听力受损的成年人中，将通过40赫兹中潜伏期反应（MLR）定义的客观阈值与主观听力测量结果进行了比较。研究了0.25、0.5和1千赫的频率。为了确保良好的频率特异性，特别挑选了存在高频听力损失的受试者。40赫兹MLR阈值通常比听力测量结果更差。平均差异约为12分贝，但在约三分之一的病例中，差异在20至30分贝之间。尽管并不完美，但低频的40赫兹MLR估计可能非常有用，值得进一步考虑，尤其是在儿童中。
