Technical Field
The invention relates to the field of audiology, in particular to a hearing-aid device capable of outputting sound with variable frequency and an application method thereof.
Background
Because the human ear is 'open' for a long time, outside sound can directly enter no matter how strong or weak, and at the moment, the strong sound needs to be 'resisted' by the middle ear function and the inner ear function, so that the introduction of loud sound is reduced, and the ear is protected. However, if hearing loss occurs in the human ear, this regulation becomes poor and loud sounds can "rush" unscrupulously into the human auditory system "causing further hearing loss. However, hearing loss has become more prevalent and severe, and data published by the WHO (world health organization) has shown that 11 billion teenagers are at risk of hearing loss worldwide due to the use of headphones. The hearing loss is generally caused by the fact that teenagers have a plurality of bad habits when using the earphones and the sound volume is involuntarily turned up.
The existing hearing aid products and auxiliary hearing earphones are based on the principle that according to hearing threshold data of individual audiogram of a deaf patient, external sound is amplified, sound pressure is increased, stimulation intensity is increased, the discharge rate of cochlear hair cells of an inner ear is improved, and the purpose of improving hearing is achieved. Obviously, this method of amplifying sound is easy to "run away" in practical use because the external sound is a random compound sound, the sound components are complex and varied, in short, the random sound must contain high-intensity sounds with different frequencies and different sound intensities, and the hearing aid uses its own microphone to pick up these sounds, which will not make a selection, and only receive them on the whole disc, then transmit them to the processor, and then output them by the speaker. This amplification process, on the one hand, can lead to a profound sound being transmitted into the ear of the user, which is often heard by the user, and on the other hand, it is easy to generate an excessive amplification, which further impairs the hearing of the user after long-term use, which is a common problem of conventional hearing aids.
At present, high-end hearing aid brands are provided with hearing aids with additional multi-channel processors, the frequency of the human ear at 125-8000 Hz can be divided into a plurality of frequency bands, and hearing aid fitters can independently set the gain, compression ratio and the like of each frequency band according to individual hearing loss states (audiogram), so that the sound entering the frequency bands of the ears can be processed according to the set gain.
