The analysis of the choice and distribution of the fixed frequencies in the course of audiometry and mechanisms of automatic regulation in the hearing system (HS) gave grounds to suppose that: 1) HS is rather a multichannel system than a single channel, the number of channels being equal to the number of frequency critical acoustic bands (that is 24); 2) not one but 24 mechanisms of threshold hearing adaptation operate in HS, one for each critical hearing band; 3) the number of fixed frequencies at which audiometry is made (125 Hz-8 kHz) should be 21 while now it is 9 and these frequencies should not change by ostave, but must correspond to central frequencies of critical hearing bands this number of frequencies being optimal.
对听力测定过程中固定频率的选择与分布以及听力系统（HS）自动调节机制的分析，有理由推测：1）HS更像是一个多通道系统而非单通道系统，通道数量等于频率临界声学频带的数量（即24个）；2）HS中运行的不是一种而是24种阈限听力适应机制，每个临界听力频带各有一种；3）进行听力测定时的固定频率数量（125赫兹 - 8千赫）应为21个，而目前是9个，并且这些频率不应以倍频程变化，而必须对应临界听力频带的中心频率，这个频率数量是最优的。
