本文通过16只豚鼠500。1,000、2,000、4,000和8,000Hz 短音刺激脑干诱发电位的分析,提示听力正常豚鼠的低频短音脑干诱发反应可能系耳蜗高频区听单位的兴奋所产生,低频短音并未比短声表现较好的频率特性。然而耳蜗高频区外毛细胞有严重损害的豚鼠,其相应的高频短音脑干诱发电位反应阚有所提高,低频短音脑干诱发电位反应阈仍正常,故短音具有频率特性。从耳蜗损害豚鼠的短声和短音脑干诱发电位反应阈的差别可以看出,短声和短音结合使用将有利于迅速而全面地反映耳蜗的功能.
In this paper, we analyzed the brainstem response induced by short guns at 500.1, 2,000, 4,000 and 8,000 Hz in guinea pigs, suggesting that the basso-brainstem responses of guinea pigs with normal hearing may be caused by the excitement of listening units in the high frequency region of cochlea, Bass tones do not perform better than short tones. However, guinea pigs with severely damaged outer hair cells in the high frequency region of the cochlea had a corresponding increase in their brainstem response potentials, and their bass response was still normal. The difference between short-sighted and short-sighted brainstem response thresholds in cochlear-impaired guinea pigs shows that the combination of short and short sounds will be useful in quickly and fully reflecting the function of the cochlea.
