What is equal loudne?

The actual loudne of the sound and the actual loudne of the human ear are not completely linear. When the volume is low, the human ear will have a physiological attenuation of the middle and high frequency hearing. The lower the volume, the more obvious the attenuation. The function of equal loudne control is to increase the volume of high-frequency and low-frequency components when the volume is low, so that the loudne ratio of the low, medium, and high parts is kept the same as the loudne ratio at the high volume. Equal loudne control meets this requirement, and equal loudne control is generally 8dB or 10dB. In order to maintain the equal loudne effect of the high and low frequency bands when the human hearing is relatively large at low volume, some pre-amplifiers have inserted equal loudne effect circuits. Consistency of ear and hearing.
