| 摘 要： | 目的:探讨同步多频听觉稳态诱发电位在豚鼠听力检测中的应用。方法:健康杂色豚鼠20只(雌性12只,雄性8只),分别进行同步多频听觉稳态诱发电位测试。同步多频听觉稳态诱发电位刺激声信号的载波频率为0.5kHz、1kHz、2kHz及4kHz。双耳上述各个频率分别以77～103Hz不同的调制频率进行调幅调制。测试时,双耳8个(每耳4个)声信号经插入式耳机同步给出。测试状态为戊巴比妥钠镇静睡眠。所有数据以SPSS统计软件分析。结果:同步多频听觉稳态诱发反应阈,在0.5kHz、1kHz、2kHz及4kHz的平均值及标准差分别为左耳:(31.00±16.19)dBSPL,(25.50±12.34)dBSPL,(18.00±6.96)dBSPL,(18.50±6.71)dBSPL;右耳:(35.00±14.33)dBSPL,(25.50±12.37)dBSPL,(20.00±9.37)dBSPL,(20.00±9.18)dBSPL。左右耳同频率之间的差异无统计学意义。结论:同步多频听觉稳态诱发电位测试具有频率特异性、客观的特点,可以作为豚鼠听力测试的备选方法。

| Abstract: | Objective To explore the use of auditory steady-state response (ASSR) to multiple simultaneous stimuli for threshold estimation in guinea pigs. Methods Twenty miscellaneous and healthy guinea pigs were examined respectively. The equipment was SMART ASSR from the intelligent hearing system. Simultaneous carrier tones (0.5 kHz, 1 kHz, 2 kHz and 4 kHz) modulated in amplitude at different rate of 77 Hz, 85 Hz, 93 Hz and 101 Hz in left ear and 79 Hz, 87 Hz, 95 Hz and 103 Hz in right ear, were presented simultane... |
