Auditory thresholds for frequency-modulated (warble) tones and narrow bands of noise in a sound field were obtained for children between the ages of eight and 48 months. Differences between the two types of stimuli centered at either 500 Hz or 4,000 Hz and among three age groups were not statistically significant (P greater than 0.01). Auditory thresholds for these frequency-selective stimuli did coincide closely with the speech awareness and spondee threshold measurements obtained in the present study, and with thresholds for complex noise obtained in previous reports. Sound field warble tone thresholds differed, however, from published data in adults and unpublished data in children. Explanations for discrepancies between data in present study and previous studies are suggested, and a cautious recommendation for the use of frequency-selective stimuli in the assessment of auditory thresholds in children is emphasized.
我们获取了8至48个月大儿童在声场中对调频（啭音）音调和窄带噪声的听觉阈值。以500赫兹或4000赫兹为中心的两种类型刺激之间以及三个年龄组之间的差异无统计学意义（P大于0.01）。这些频率选择性刺激的听觉阈值确实与本研究中获得的言语觉知和单音节词阈值测量结果以及先前报告中获得的复合噪声阈值密切相符。然而，声场啭音阈值与成人已发表数据和儿童未发表数据有所不同。文中提出了本研究数据与先前研究数据存在差异的解释，并强调在评估儿童听觉阈值时使用频率选择性刺激需谨慎。
