Embodiment Construction

[0047] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0048] 1. Spectacle digital hearing aid sound source localization model

[0049] The present invention establishes as figure 1 Sound source localization model for glasses digital hearing aid shown. In this model, four microphones are installed on the glasses frame to form a four-element microphone array. Four sound signals received by four microphones are used to calculate the spatial position of the sound source. The calculated spatial position of the sound source can be further utilized by other modules of the hearing aid for speech enhancement or noise suppression.

[0050] like figure 2 As shown, the spatial coordinates take microphone 1 as the origin, the line connecting microphone 1 and microphone 2 points to the positive direction of the x-axis, the direction of microphone 1 and microphone 4 points to the positive direction of the...

Abstract

The invention provides a sound source positioning method for a glasses type digital hearing aid. A sound source space position obtained according to the calculation of the sound source positioning method can be further utilized by other modules of the hearing aid, so as to carry out speech enhancement and noise suppression. A quaternionic microphone matrix model of the glasses type digital hearing aid is first established, a formula for carrying out sound source positioning on the model is deduced, and the time delay difference from a sound source to a microphone in the formula is estimated by a self-adaptation characteristic value decomposition algorithm. Under the environment of noise and resonance, the provided method has the characteristics of good robust performance, high positioning precision, small calculating amount and easy real-time realization.

Description

1. Technical field [0001] The invention relates to a method for locating a sound source of a digital hearing aid for glasses. 2. Background technology [0002] Wearing hearing aids is the most effective method in the auxiliary treatment of hearing-impaired patients. With the development of advanced DSP technology and modern signal processing technology, all-digital hearing aids have gradually replaced traditional analog hearing aids. With the help of speech signal processing algorithms, all-digital hearing aids are positioned to improve the patient's speech recognition rate, rather than simply amplifying the sound. Sound source localization and tracking is an important method for the human auditory mechanism to improve the speech recognition rate. It can help the human ear distinguish speech in environmental noise, and separate the speech of interest from the voices of multiple speakers. In the speech processing algorithm of digital hearing aids, the sound source localizat...
