Abstract

The invention discloses a noise reduction earphone audio processing method, a noise reduction earphone, a device and a readable storage medium. The method comprises the steps of: obtaining a first sound signal collected by a feedback microphone, and determining a first transfer function corresponding to the first sound signal; obtaining a second sound signal collected by a feed-forward microphone, and constructing a filtered sound signal according to the first transfer function and the second sound signal; and determining an Eustachian tube sound signal corresponding to the filtered sound signal, performing ear blockage elimination processing on the Eustachian tube sound signal to obtain a target sound signal, and outputting the target sound signal. The noise reduction effect of the earphone is improved.

Description

technical field [0001] The present invention relates to the technical field of earphones, in particular to an audio processing method for noise-cancelling earphones, a noise-cancelling earphone, a device, and a readable storage medium. Background technique [0002] Most of the headphones currently on the market use a single noise reduction mode. Regardless of whether the user's environment is quiet or noisy, when the active noise reduction is turned on, the same mode will be used to cancel the noise in the low frequency band. This earphone noise reduction mode, in a quiet environment, if the low-frequency noise is reduced, the user will have a sense of negative pressure, resulting in an uncomfortable wearing experience. In addition, because different users have different sensitivity to sounds of different frequencies, and there may be differences between the left and right ears. Existing products are not designed to be compatible with different characteristics of users, so ...
