In order to ascertain if any substantial difference exists in the auditory middle responses (AMR) between adults and young children, a digital high-pass (HP) filtering technique was applied to the responses in 26 young children aged 1-7 years and nine adults with normal hearing. Two significant differences were found between the HP-filtered responses in children and those in adults. Pa in the responses from adults was consistently recognized with HP filtering up to 50 Hz, while Pa in young children was effectively detected only with 20 Hz HP filtering. It was mostly eliminated when the HP filter was set at 30 or 40 Hz. Pb was identified in most of the adult responses, particularly with HP filtering at 30 Hz. On the other hand, it was not visually distinguished in the responses from young children with any HP filter setting.
为了确定成人和幼儿的听觉中潜伏期反应(AMR)是否存在任何实质性差异,对26名1至7岁听力正常的幼儿和9名成人的反应应用了数字高通(HP)滤波技术。在儿童和成人的HP滤波反应之间发现了两个显著差异。成人反应中的Pa在高达50 Hz的HP滤波下始终能够被识别,而幼儿的Pa仅在20 Hz的HP滤波下才能有效检测到。当HP滤波器设置为30或40 Hz时,它大多被消除。在大多数成人反应中都能识别出Pb,特别是在30 Hz的HP滤波下。另一方面,在任何HP滤波器设置下,幼儿的反应中都无法在视觉上区分出Pb。
