Description
Technical Field
The invention relates to the technical field of microcontrollers, in particular to a wide dynamic compression hearing aid method based on earphone equipment and related equipment.
Background
At present, a plurality of users with hearing disabilities in the world cannot hear or clearly hear other people speaking, music, radio or various sounds of which the natural world falls within the hearing range of human ears (theoretically within 20000 Hz), such as alarms, doorbells, loudspeakers, prompting tones, noisy background sounds and the like, like normal people. The hearing impairment is difficult to cure and can only be solved by wearing hearing aids.
However, existing hearing aids can help hearing impaired patients to re-hear the sound key by means of a built-in hearing aid specific chip containing a plurality of sub-modules (each sub-module being a corresponding software and specific hardware component). Among them, the wide dynamic compression submodule is one of them.
Whereas wide dynamic compression has the following effects:
1. compressing an external original audio frequency segment to an audio frequency segment which can be heard by hearing loss persons; because normal people have a wide hearing range, for example, the normal people can hear the sound in the frequency range of 20-20000Hz, and the hearing loss people may hear the sound in the frequency range of 500-. Otherwise, the sound information received by the hearing impaired person is lost, i.e. cannot be heard or cannot be heard.
2. Compressing the external original sound loudness to the sound loudness that can be heard by hearing loss persons; because the loudness range of sound that normal people can hear is larger than-30 dB-120 dB, and the hearing loss people can not hear the sound with loudness larger than or smaller than a certain amplitude. The amplitude of the loudness changes of the external original sound must therefore be compressed: too little enhancement of loudness and too much attenuation of loudness. This ensures that the original sound energy is fully accepted by the offending person as much as possible.
However, the wide dynamic compression hearing aid module must be supported by a chip dedicated for hearing aids at present, and the wide dynamic compression hearing aid module is useless for hearing health people, so that the module is not provided on general earphone equipment, and therefore, the earphone chip does not support the wide dynamic compression hearing aid function.
Thus, the prior art has yet to be improved and enhanced.
