Method and apparatus for audio signal control

Abstract

An audio signal control method and apparatus for hearing protection are disclosed. The audio signal control method includes: producing an output level of an audio signal being input; determining whether the ratio of an output time of the audio signal within a preset time duration to a permissible time corresponding to the produced output level is greater than or equal to a limit reference value; and limiting, when the ratio of the output time to the permissible time is greater than or equal to the limit reference value, the output level of the audio signal to a preset level.

Dependencies are inferred from the claim text.
