Abstract

The patent of the present invention provides a hearing aid method and device based on virtual surround sound technology, which is applied to hearing aid equipment, including: obtaining sound signals from the surrounding environment to generate different input signals; generating different spectrograms of the input signals; Select the optimal main sound source signal of the spectrogram of the input signal as the first output signal output; compare the sound source signal of the spectrogram of the input signal by difference, and generate a difference between the hearing aid device and the main sound source. It is designed with a non-single sound signal input port, and the position information of the main sound source with the hearing aid device as the coordinate origin can be deduced through the speed of sound decay, propagation speed, etc.; the second output signal and the first The differential output of the output signal enables the sound to be distributed to two independent channels, so as to achieve a good sound localization effect.

Description

technical field

[0001] The patent of the present invention relates to the field of hearing aids, in particular to a hearing aid method and device based on virtual surround sound technology. Background technique

[0002] The basic structure of a hearing aid includes four main parts: a microphone, an amplifier, an earphone, and a power supply. The hearing aid converts the sound signal into an electrical signal (electrical energy) and sends it to the amplifier. The amplifier amplifies the input weak electrical signal and then transmits it to the output. Transducer, the output transducer is composed of earphone or bone vibrator. Its function is to convert the amplified strong signal from electrical energy into acoustic signal (sound energy) or kinetic energy output. Therefore, the output signal ratio of earphone or bone vibrator is higher than The original signal received by the microphone is much stronger, which can compensate the hearing loss of the hearing impaired to varying...
