Explanation:
Frequency Response: 2dB boost at 10 kHz and -2 dB at 20 kHz (ref. 1 kHz)

频率响应:10 kHz频率放大2dB,20 kHz放大-2 dB (相对于 1 kHz)

参考1: https://baike.baidu.com/item/频率响应

参考2: https://books.google.co.th/books?id=uXkqBgAAQBAJ&pg=PA531&lp...


"... Thus a specification of 45 Hz-17 kHz (+/- 3 db ref. 1kHz) states that the response at any frequency between the limits will not deviate from the response at 1 kHz by more than 3 db Upwards or downwards."
