听觉功能的测定需用多种类型的刺激声,它们各有不同的特点,其中最重要的是频谱。在听觉研究的文献中,很少有对各种刺激声的频谱描述,偶尔有对个别刺激声的分析,精度也不高,一般只提供1/3倍频带的功率谱而已。对刺激声的准确频谱缺乏了解,常使听觉实验的结果分析难以深入,有时甚 The auditory function of the need to use many types of stimuli, they have different characteristics, the most important of which is the spectrum. In the literature of auditory research, there is very little spectral description of various stimuli sounds. Occasionally, the analysis of individual stimuli sounds is not very accurate and generally only provides a power spectrum of 1/3 octave band. Lack of understanding of the exact spectrum of irritation sounds often makes it difficult to analyze the results of auditory experiments and sometimes
