短声极性对单导听性脑干诱发电位（ABEP）的影响已有报道，表明疏波短声所诱发的波V潜伏期较密波短声所诱发的短。但短声极性对ABEP其它成分的影响意见仍不一致。经同时刺激双耳诱发ABEP的某些成分不同于分别刺激左耳及右耳诱发反应之和，二者的差别称为双耳交互作用（BI），其 The effect of short-tone polarity on single-lead auditory brainstem response potential (ABEP) has been reported, indicating that the short-sound wave induced by shortwave spikes is shorter than that induced by short-sighted shortwave sounds. However, the impact of short-sound polarity on other ABEP components is still not consistent. Some components of ABEP induced by simultaneous stimulation of both ears are different from the sum of stimuli induced by left and right ears respectively. The difference between them is called binaural interaction (BI)
