Description
Technical Field
The invention relates to the technical field of hearing-impaired disabled treatment equipment, in particular to a hearing-aid device assisted by touch and a hearing-aid system.
Background
According to the sample survey of the national disabled, 2780 thousands of the prior hearing-impaired disabled people in China are shown, wherein more than 2000 thousands of adult-impaired disabled people exist, the incidence rate of the senile deafness can reach about 60 percent, and the number of people is increased year by year. However, this is only registered data, and the number of actual hearing loss patients is significantly higher than 2000 ten thousand.
The hearing aid device is a tool, equipment, a device, an instrument and the like which are helpful for hearing-impaired disabled persons (hereinafter, hearing-impaired patients) to improve hearing impairment and further improve the conversation capacity with other people. In a broad sense, any device which can effectively transmit sound into the ear can be regarded as a hearing aid device, and in a narrow sense, the hearing aid device is an electroacoustic amplifier which amplifies the sound to make the deaf person hear the sound which is originally not heard clearly, and the device can be called as a hearing aid device.
There are mainly four types of hearing aid devices worn by individuals: a hearing aid device of the cassette type, a hearing aid device of the spectacle type, a hearing aid device of the behind-the-ear type, and a hearing aid device of the custom type. The box-type hearing-aid device can meet the requirements of severely deaf children and old people, so that more users can be used for the children and the old people. The glasses type hearing aid device can meet the requirements of patients with ametropia and deafness, and can be used for cross-linking signals of a person who suffers from single-side deafness, normal another side of the person or has a low degree of deafness by means of the glasses type hearing aid device. The ear-carried hearing aid is placed behind the ear, the microphone opening is connected with a sound-conducting hook made of hard plastic tube, and said sound-conducting hook is hung on the root portion of upper edge of auricle, so that said hook can be placed into the concha cavity and external meatus of ear mould, and said ear-carried hearing aid is placed behind the ear, and is concealed by hair, and is not found by others, so that it can meet the psychological requirements of deaf person, and its general utilization rate can be up to about 60%. The customized hearing aid device is a generic name of "in-ear hearing aid device", "in-canal hearing aid device", and "deep-canal hearing aid device". The customized hearing-aid device has the following characteristics: is customized according to the shape of each ear and is suitable for each ear. Thus, the wearing is more comfortable and the taking and wearing are easier.
In addition, most of the deaf patients are sensorineural deafness, and a considerable number of them have a phenomenon of positive stress: they feel difficult to hear with light sounds but are intolerant to louder sounds, i.e., the dynamic range of loudness they tolerate is significantly reduced. Hearing aid devices are typically capable of amplification, enabling simultaneous compression and limiting functions.
Audiological studies have shown that the low frequency part of speech signals contains the envelope (envelope) information and the first peak of vowels, while the high frequency part contains fricatives, etc., and the low frequency and high frequency are important for semantic extraction of the primary and secondary auditory cortex of the brain, especially for hearing-impaired patients. However, the residual hearing of the hearing impaired patient is usually concentrated on low frequency, and it is difficult for the ordinary hearing aid to transmit high frequency information through the auditory channel, so that the hearing impaired patient cannot understand the semantic meaning even wearing the hearing aid.
To address this challenge, haptic assisted hearing devices have become a leading effective solution. The touch assistance means that vibration is utilized to effectively transmit the missing high-frequency part of the common hearing aid device to the brain center, and the brain center fuses touch sense and auditory sense to improve the language recognition rate of the hearing-impaired patient. However, the existing haptic-assisted hearing aid devices cannot achieve a high speech recognition rate, and cannot effectively improve the adaptability of the hearing aid device according to the source and direction of sound, so that the hearing aid effect is good and bad, the fluctuation is high, and the hearing aid device is difficult to accept by patients.
Therefore, how to design a high-performance haptic-assisted hearing device suitable for various hearing scenes and efficiently integrate hearing and haptic effects becomes a technical problem that needs to be solved by those skilled in the art.
