With the popularity of smart mobile devices such as mobile phones and tablets, enjoying audio entertainment services anytime and anywhere is the most common life scene. Young people are the mainstay of audio-playing applications, and children are beginning to get closer to electronics and audio applications.

technical problem

According to medical research, adults who are exposed to more than 85dB of sound for a long time will cause damage to the hearing system, while children in the critical period of growth and development are more vulnerable to adult hearing. 60-85dB is acceptable for children's growth and development. A reasonable maximum volume range. More and more users choose to use headphones to listen to audio. Because their specific structure is more in-depth contact with the organs of the hearing system, it brings more damage than the speakers of traditional devices. Therefore, it is medically recommended to use audio applications especially. In use with the headphone mode, the volume should be limited to 85dB or less, and there is a certain rest time after listening for 1 hour continuously, thus protecting the hearing system, and children should be more protected in the above scenes.

Therefore, there is an urgent need in the field of digital audio technology for an audio playback system and a hearing protection method thereof for audio playback, which can well protect the listening system of the listener and reduce the damage caused by long-time, high-decibel audio playback, especially It provides more direct protection when the child listens to use, avoids the child's fragile hearing system being hurt, and considers both the speaker and earphone modes, and can choose, the mode is more diverse, and the hearing protection mode switch is added. Listeners can both protect their hearing and have a good experience. They are good for the health of the audience and the proper use of the audio application system.
