Audio processing method, device, earphone, terminal equipment and storage medium

Abstract

The embodiment of the invention discloses an audio processing method and device, an earphone, a terminal device and a medium, and the audio processing method comprises the steps of obtaining a to-be-played audio frame under the condition that an audio is played, the audio frame comprising a plurality of sub-bands; determining the energy value of each sub-band, wherein the energy values of the sub-bands are in one-to-one correspondence with the auditory threshold values; and under the condition that the energy value of the at least one sub-band is greater than the corresponding auditory threshold, carrying out attenuation and / or voltage limiting processing on the at least one sub-band. According to the embodiment of the invention, the hearing protection processing of the audio frame playedby the audio system in different frequency bands can be realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio technology, and in particular, to an audio processing method, device, earphone, terminal device, and storage medium. Background technique [0002] More and more consumers use earphones to listen to music. If the music is played at a high volume for a long time, it is easy to cause damage to the user's ears. With the current level of human technology, the damage to the hearing organs is generally irreversible. Therefore, hearing Protection is very important. [0003] At the same volume, medium and high frequencies are much more damaging to the human ear than low frequencies; currently, when the energy corresponding to the full frequency band of the audio system output audio is greater than the human ear's hearing safety threshold, the energy corresponding to the full frequency band will be adjusted to be less than or equal to the human ear. Hearing safety threshold to solve the damage of...

Problems solved by technology

However, when the audio output by the system tends to be a mid-to-high frequency single tone (that is, a single frequency point, or a single frequency point and its higher harmonics), the total energy of the entire frequency band of the audio output by the system is often less than the safe threshold, but still It will cause hearing damage to the human ear. At this time, the above method will not solve the damage of high frequency to the human ear.

In addition, in the prior art, the method of attenuating or compressing the entire frequency band is usually used to adjust the energy corresponding to the entire frequency band to be less than or equal to the safety threshold of human hearing, which will cause the user to not hear the complete details, which will easily lead to Users turn up the volume, which is not conducive to hearing protection
