Method and device for adjusting volume of earphone, earphone and storage medium

Abstract

The invention is suitable for the technical field of earphones, and provides a method and device for adjusting the volume of an earphone, the earphone and a computer readable storage medium. The method comprises the following steps: acquiring an audio digital signal input into an earphone; calculating the output sound pressure level of the earphone according to the audio digital signal; acquiring an environment noise signal; calculating a noise sound pressure level according to the environment noise signal; acquiring a corresponding safe sound pressure level according to the noise sound pressure level; and adjusting the output sound pressure level according to the safe sound pressure level. According to the invention, the corresponding safe sound pressure level can be obtained according to the noise sound pressure level while the output sound pressure level of the earphone is calculated according to the audio digital signal input into the earphone, the output sound pressure level of the earphone is adjusted by referring to the safe sound pressure level, it can be guaranteed that a user can hear clearly, and hearing protection of the user is facilitated.

Description

technical field [0001] The present application belongs to the technical field of earphones, and in particular relates to a method and device for adjusting the volume of an earphone, an earphone and a computer-readable storage medium. Background technique [0002] At present, the number of people wearing headphones is increasing, and there are more and more usage scenarios. Some children have begun to use headphones in their study and life. However, most people usually do not have the concept of hearing protection. In order to hear more clearly and cover the surrounding noise, etc., the volume of the earphones is turned up, which makes the sound field output of the earphones too strong, and long-term use is likely to cause hearing loss. [0003] Since many people's ears are not very sensitive to sound, they cannot judge the sound pressure level subjectively during the listening process. Even people with sensitive ears may not be able to accurately judge whether the volume is...

Problems solved by technology

However, most people usually do not have the concept of hearing protection. In order to hear more clearly and cover the surrounding noise, etc., the volume of the earphones is turned up, which makes the sound field output of the earphones too strong, and long-term use is likely to cause hearing loss to the human ear.

[0003] Since many people's ears are not very sensitive to sound, the sound pressure level cannot be judged subjectively during the listening process.

Even people with sensitive ears may not be able to accurately judge whether the volume is too loud after their ears have adapted to the high volume environment after listening to it for a long time.
