Problems solved by technology

However, the prompt sound played by the speaker affects the user's listening experience, and when the relative position of the earphone and the ear canal changes after the user wears the earphone, the earphone cannot obtain the above-mentioned changed noise reduction parameters
[0005] Obviously, the existing earphones cannot solve the above problems

Abstract

The invention relates to a method and device for determining earphone noise reduction parameters and a computer readable medium. The earphone comprises a loudspeaker, an in-ear microphone and a filterassembly. The method comprises the following steps of: playing a low-frequency audio signal of which the frequency is out of the auditory range of human ears by a loudspeaker, determining a current transfer function of a transmission path from the loudspeaker to the in-ear microphone or a parameter of a current audio signal acquired by the in-ear microphone, determining a current noise reductionparameter based on the current transfer function or the parameter of the current audio signal by referring to N groups of corresponding relationships between a preset transfer function or a parameterof a preset audio signal and a preset noise reduction parameter, the noise reduction parameter comprising a filter coefficient of a filter enabled in the filter assembly, and configuring the filter assembly with the current noise reduction parameter to perform noise reduction. By playing the low-frequency audio signals beyond the auditory range of the human ears for many times, the dynamic adjustment of the noise reduction parameters of the earphone can be realized, the noise reduction effect in different use scenes is ensured, and meanwhile, the listening experience of a user is improved.

Description

technical field [0001] The present disclosure relates to the field of earphones, and more particularly, to a method, device and computer-readable medium for determining noise reduction parameters of earphones. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones have become an indispensable daily necessities for people. Headphones with noise suppression function can enable users to enjoy a comfortable noise reduction experience in various noisy environments such as airports, subways, airplanes, restaurants, etc., and are increasingly widely recognized by the market and customers. However, different noise conditions, different earphone wearing styles, and different ear canal structures will all affect the noise suppression function of the existing earphones, and also bring users an unsatisfactory use experience. [0003] First of all, the noise reduction effect of headphones is greatly affected by different we...
