要了解成年树鼩的ABR波形特征，必须了解健康树鼩的听觉灵敏度和听觉功能。15只树鼩（30耳）在1 - 60 kHz的11个不同频率下用短声和短音刺激。记录并分析ABR波形。短声刺激后10 ms内ABR由5 ~ 7个正波组成，Ⅲ分量听阈平均为27.86 ± 3.78dBSPL。第三波是最大和最清晰的。ABR阈值与纯音刺激频率呈“U”型曲线关系。树鼩的敏感频率约为8 kHz。随着刺激频率的增加，lavonium系统地减少。ABR波III的振幅随声压级的增加而增加。这些结果为今后树鼩听力疾病的研究提供了实验依据。
To characterize the patterns of ABR waves in tree shrews, we must understand the hearing sensitivity and auditory function of healthy adult tree shrews. Fifteen tree shrews (30 ears) were stimulated with clicks and tone-pips at 11 different frequencies from 1 to 60 kHz. The ABR waves were recorded and analyzed. The ABR consisted of five to seven positive waves in the first 10 ms after a click stimulus, and the average hearing threshold of component III was 27.86 ± 3.78 dB SPL. Wave III was the largest and most clear. The ABR threshold was related to the tone-pip sitmulus by a "U" shaped curve. The sensitive frequency was approximately 8 kHz in tree shrews. The latencies systematically decreased with increasing stimulus frequencies. The ABR amplitudes of wave III increased as the sound pressure level increased. All of these results provide an empirical basis for future studies of hearing diseases in tree shrews.
