Debugging method, device and equipment of hearing-aid earphone

Abstract

The invention discloses a debugging method, device and equipment for a hearing-aid earphone. The debugging method comprises the following steps: extracting signal envelope characteristics of audio collected in a real scene; simulating a composite sound signal of a real scene by using the signal envelope characteristics to serve as a scene mode of the test equipment; performing preliminary debugging on the hearing-aid earphone by using a scene mode in the test equipment; and further debugging the hearing-aid earphone through the main observation earphone to obtain the debugged hearing-aid earphone. The scene mode audio of the test equipment is set according to the signal envelope characteristics obtained according to the real scene, and the noise reduction capability of low-frequency, intermediate-frequency and high-frequency signals of the hearing-aid earphone in different scene modes can be accurately debugged.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a debugging method, device and equipment for hearing aid earphones. Background technique [0002] With the rapid development of the world economy, the problem of aging is becoming more and more serious. International aging refers to the fact that the population aged 60 and above in a country or a region reaches or exceeds 7% to 10% of the total population. Relevant authoritative research institutions have interpreted that the scale of my country's aging population is on the rise. Facing the increasingly severe aging situation in our country, whether the elderly can spend their old age in peace is the most concerned issue of our people. With the aggravation of the aging problem, the hearing impairment of the elderly has also attracted the attention of the general public, especially in today's era where language communication is the mainstay, hearing impairment will directly aff...

Problems solved by technology

[0007] However, simply switching the ambient scene audio in the hearing aid earphone test equipment as a different scene mode to test the noise reduction ability of the low frequency, intermediate frequency, and high frequency signals of the hearing aid earphones cannot accurately analyze some uncollected non-characteristic noises. The distribution of sudden noise and sudden noise on the spectrogram will also cause some intermediate frequency signals containing voice information to be suppressed, and the precise adjustment of intermediate frequency signals cannot be realized. In the end, the output voice of the hearing aid earphones is like a machine sound, which is distorted and does not sound good. nature

[0008] In addition, the subjective listening method in the anechoic room is separated from the actual environment scene, and cannot handle some potential noise information, and there is no good quantitative feedback mechanism, which is not conducive to subsequent parameter fine-tuning

Therefore, the current debugging method of acoustic performance of hearing aid earphones takes a lot of time and workload, and it is difficult to adjust the effect of noise reduction and speech hearing aid to a suitable range.

This method lacks quantification standards, cannot accurately debug the noise suppression effect of the intermediate frequency signal, and cannot maximize the acoustic performance of the multi-channel hearing aid earphones. The final result will lead to varying degrees of distortion and machine sound in the output audio. obvious
