Abstract

The present invention relates to a method for protecting hearing. The method includes steps: detecting volume level of environmental noise, whereby obtaining an referenced actual audio energy value; receiving analog sound signals from a sound signal resource; transforming the analog sound signals to digital sound signals; sampling the digital sound signals and obtaining a plurality of amplitude values; calculating a sound energy value during a predetermined time according to the amplitude values; generating a hearing protection signal when the sound energy value reaches a predetermined value; responding to the hearing protection signal to reduce gain value automatically. The present invention also provides a sound output device for protecting hearing. The present invention not only protects a user's hearing, but also causes the user to enjoy music in a proper volume when the environmental sound is noisy.
