Tone pips of suprathreshold intensity were used to elicit 7 potentials in the nanovolt range. The acoustic nerve response (I) and 4 brainstem potentials (II-V) were studied in 8 normal listeners in regard to varying acoustic polarity (rarefaction vs condensation). Rarefaction and condensation stimuli produced different responses. In the alternating mode, which helps to suppress stimulus related artifacts, waves may be generated solely as a function of the averaging process if the responses of the two types of tone pips are almost out of phase. Rarefaction tone pips exhibited a better synchronizing effect on auditory unites in the periphery and in brainstem areas. The different responses evoked by stimuli of different polarity must be recognized and controlled in neurologic application of the test.
使用阈上强度的短纯音来引出纳伏范围内的7种电位。在8名正常听力受试者中，研究了听神经反应（I）和4种脑干电位（II-V）对不同声音极性（疏波与密波）的变化情况。疏波和密波刺激产生了不同的反应。在交替模式下，这有助于抑制与刺激相关的伪迹，如果两种类型短纯音的反应几乎异相，那么波形可能仅作为平均过程的函数而产生。疏波短纯音在外周和脑干区域对听觉单元表现出更好的同步作用。在该测试的神经学应用中，必须认识并控制由不同极性刺激引起的不同反应。
