LOUDNESS CONTROL METHOD AND DEVICE

摘要

PURPOSE: A loudness control method and a device is provided to make a simple circuit formation by getting a loudness compensation level. CONSTITUTION: The loudness control method comprises steps of: adding a first constant for a loudness compensation into a volume level if the signal of a low-frequency zone by judging if a sound signal is the signal of the low-frequency zone, and getting the added result as a loudness compensation level of the low-frequency zone; judging if the sound signal is the signal of a high-frequency zone when the sound signal is not the signal of the low-frequency zone.
