To determine the threshold of multiple auditory steady-state evoked responses(ASSR) of young adults with normal hearing, and to offer essential diagnosticate datas.
ASSR were examined in 22 (44 ears) young adults with normal hearing. There were 11 men and 11 women in 22 young adults.
Average threshold of ASSR were about 40 to 60 dBHL between 0.25-8.0 kHz, and they became higher from low frequency to high frequency. Average threshold of MFSSR were 40 dBHL at 0.25-0.5, 1 kHz, and about 45 dB HL at 2 kHz, and about 50 dB HL at 4 kHz, and about 60 dB HL at 8 kHz. Difference values were about 25 to 55 dB HL between average threshold values of ASSR and hearing, and they became higher from low frequency to high frequency, those were about 25 dBHL at 0.25 kHz, about 30 dBHL at 0.5 kHz, about 35 dBHL at 1 kHz, about 40 dB HL at 2 kHz, about 50 dB HL at 4 kHz, about 55 dBHL at 8 kHz.
There is a definite numeral value between threshold of ASSR and hearing in young adults with normal hearing. Pure tone hearing threshold can be conferred by examining the threshold of ASSR and by using the definite numeral values.
测定听力正常的年轻成人的多频听觉稳态诱发反应（ASSR）阈值，提供必要的诊断数据。
对22例（44耳）听力正常的年轻成人进行ASSR检测。22例年轻成人中男性11例，女性11例。
0.25 - 8.0kHz之间ASSR平均阈值约为40至60dBHL，且从低频到高频逐渐升高。多频ASSR（MFSSR）在0.25 - 0.5kHz、1kHz时平均阈值为40dBHL，2kHz时约为45dBHL，4kHz时约为50dBHL，8kHz时约为60dBHL。ASSR平均阈值与听力之间的差值约为25至55dBHL，且从低频到高频逐渐升高，在0.25kHz时约为25dBHL，0.5kHz时约为30dBHL，1kHz时约为35dBHL，2kHz时约为40dBHL，4kHz时约为50dBHL，8kHz时约为55dBHL。
听力正常的年轻成人ASSR阈值与听力之间存在明确数值关系。通过检测ASSR阈值并利用该明确数值可推断纯音听力阈值。
