Problems solved by technology

Conversely, when the noisy environment enters the quiet environment, if you continue to listen at the original volume, you will feel that the sound pressure is too loud, harsh, and even cause hearing discomfort. You need to manually lower the volume of the headphones or the player
It affects the user experience so much that it may even damage the hearing

Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The design idea of ​​the present invention is that: during the use of the existing earphones, the requirements for the volume of the earphones’ playback sound are different under different environments, and the user needs to manually adjust the gain of the earphones according to the changes in the environment to reduce the volume of the earphones or the player. Inconvenient, poor user experience. The common earplugs wi...

Abstract

The invention discloses a headphone gain adjustment method and device as well as electronic equipment. The method comprises the following steps: acquiring an acoustical signal collected from an ear canal, wherein the acoustic signal is a mixed signal of an audio signal and a noise signal; analyzing the acoustic signal to calculate a gain adjustment value; and adjusting output gain under control onthe basis of an original output gain according to the gain adjustment value. The acoustic signal in the ear canal is collected by a microphone in a headphone, and the components of the acoustic signal are analyzed to calculate the gain adjustment value in order to adjust the gain setting at an audio output end of an earplug, so that the adaptability of the headphone playing volume under differentnoise environments is ensured, and the auditory feel of a user is improved.

Description

technical field [0001] The invention relates to the technical field of sound signal processing, in particular to a method, device and electronic device for adjusting the gain of an earphone. Background technique [0002] In daily use, you will find that when listening to music with earplugs, when you go from a quiet environment to a noisy environment, due to the masking effect of environmental noise interference, the clarity of the music information will decrease, and you need to manually increase the volume of the earphones or player. The greater the sound pressure level of the ambient noise, the more scales need to be increased. Conversely, when the noisy environment turns into a quiet environment, if you continue to listen at the original volume, you will feel that the sound pressure is too loud, harsh, and even cause hearing discomfort. You need to manually lower the volume of the headphones or the player. This affects the user experience and may even damage hearing. ...
