中心频率为0.4、1、2、4和10 kHz的倍频程噪声阈值和中心频率为10和20 kHz的1/3倍频程噪声阈值分别来自3~5岁儿童和对照组。所有频率的阈值在3到5岁之间降低。从5岁到成年，阈值进一步降低，但20 kHz的刺激除外，儿童的阈值比成年人低。这些结果从耳朵机械特性和神经编码效率的可能与年龄相关的变化的角度进行了讨论。
Thresholds for octave-band noises with center frequencies of 0.4, 1, 2, 4, and 10 kHz, and 1/3-octave-band noises with center frequencies of 10 and 20 kHz, were obtained from children 3-5 years of age and from a comparison group of adults. Thresholds for all frequencies decreased between 3 and 5 years of age. Thresholds decreased further between 5 years of age and adulthood, except for the 20-kHz stimulus, for which children had lower thresholds than adults. These results are discussed in terms of possible age-related changes in the mechanical properties of the ear and in the efficiency of neural coding.
