Two simultaneously presented maximum length sequences (MLSs) were used to investigate temporal nonlinearities. Not only did the recorded auditory evoked brain stem responses to these stimuli predictably increase in latency and decrease in amplitude as a function of the temporal interactions between MLSs, but thresholds were elevated by more than 20 dB. Simultaneous MLS paradigms make it possible to investigate a number of nonlinearities in the auditory system efficiently. This study also demonstrated that binaural MLS techniques can be used to assess auditory function even in individuals with asymmetric hearing losses without fear of crossover effects.
使用两个同时呈现的最大长度序列（MLS）来研究时间非线性。不仅记录到的对这些刺激的听觉诱发脑干反应随着MLS之间的时间相互作用而可预测地增加潜伏期并降低幅度，而且阈值升高超过20分贝。同时MLS范式使得有效研究听觉系统中的多种非线性成为可能。这项研究还表明，双耳MLS技术可用于评估即使是听力损失不对称的个体的听觉功能，而无需担心交叉效应。
