短声和短纯音是脑干反应测听中最广泛使用的刺激。短声波形不仅取决于电脉冲宽度,而且与使用的换能器型号、耳朵耦合方式以及所用的测量方法都密切相关。另一方面,由于短纯音在同样实验条件下表现的变化较小,因此短纯音能更精确地由电刺激参数来决定。用短纯音交替改变电极性的刺激所引起的声学抵消也比短声好。引言听觉脑干反应(ABR)的波形会受到 Short and short pure tones are the most widely used stimuli in brainstem response audiometry. The short waveform depends not only on the electrical pulse width but also on the type of transducer used, the way the ear is coupled, and the measurement method used. On the other hand, the short pure tone can be more accurately determined by the electrical stimulation parameters because short pure tones show less variation under the same experimental conditions. The acoustic cancellation caused by the alternation of the electrical polarity with a short pure tone is also better than the short sound.
