频率和临界带宽之间的关系，以及临界频带速率（在树皮）的分析表达式的准确性和简单性进行评估的目的，在语音感知研究和语音技术的应用。等效矩形带宽（ERB）被认为是频率分辨率的量度，而经典临界带速率被认为是张力性位置的量度。对于频率与临界带速率的转换以及频率与临界带速率的转换，提出了一个可逆公式z = [26.81/（1 + 1960/f）]-0.53。在感知基本元音共振峰的频率范围内（0.2-6.7 kHz），它在.+-内一致。0.05树皮用树皮量表，最初以表格的形式出版。
Accuracy and simplicity of analytical expressions for the relations between frequency and critical bandwidth as well as critical-band rate (in Bark) are assessed for the purpose of applications in speech perception research and in speech technology. The equivalent rectangular bandwidth (ERB) is seem as a measure of frequency resolution, while the classical critical-band rate is considered a measure of tonotropic position. For the conversion of frequency to critical-band rate, and vice versa, the inversible formula z = [26.81/(1 + 1960/f)]-0.53 is proposed. Within the frequency range of the perceptually essential vowel formants (0.2-6.7 kHz), it agrees to within .+-. 0.05 Bark with the Bark scale, originally published in the form of a table.
