目的：Werner和Bargones（1991）观察到4-10 kHz噪声带可以在婴儿期掩盖1 kHz信号。本研究的目的是探讨远程噪声掩蔽是否延伸到学龄期。设计：听众是4-6岁，7-9岁，和成年人。检测阈值测量的1 kHz的信号在安静和存在的远程频率噪声。在单独的条件下，掩蔽水平为40或60 dB SPL。结果：平均而言，阈值为1 kHz的信号升高的存在下的远程频率噪声为4-6岁的孩子，但不是7-9岁的孩子或成人。组的平均阈值是相似的掩蔽水平，表明nonperipheral effects.Conclusions：易感性远程频率掩蔽在儿童中延伸到4-6岁的一些儿童。
Objective:Werner and Bargones (1991) observed that a 4–10-kHz noise band can mask a 1-kHz signal during infancy. The purpose of this study was to examine whether remote-noise masking extends into the school-aged years.Design:Listeners were 4–6-yr-olds, 7–9-yr-olds, and adults. Detection thresholds were measured for the 1-kHz signal in quiet and in the presence of the remote-frequency noise. In separate conditions, masker level was either 40 or 60 dB SPL.Results:On average, thresholds for the 1-kHz signal were elevated in the presence of the remote-frequency noise for 4–6-yr-olds, but not for 7–9-yr-olds or adults. Group average thresholds were similar across masker levels, indicating nonperipheral effects.Conclusions:Susceptibility to remote-frequency masking in children extends to 4–6 yrs of age for some children.
