A hearing aid device with variable frequency output sound and its application method

Abstract

The invention discloses a hearing-aid device with variable frequency output sound, which comprises an input port, a memory regulator, a processor and a speaker, the input port, the memory regulator and the speaker are all connected to the processor, and the memory regulator can be written into the hearing aid of the patient. Figure and / or HLD data, the processor can embed the algorithm of variable frequency band number and variable bandwidth, there are multiple speakers; the input port is configured to input sound signal; the processor is configured to receive the sound signal from the input port and according to the sound The signal and the data stored in the regulator change the number of frequency bands and bandwidth, and then output the sound signal by controlling different numbers of speakers; the processor can independently control the opening and closing of each speaker. An application method of the above-mentioned hearing aid device is also disclosed. The hearing aid device can realize the control of the number of frequency bands and bandwidth, change the disadvantages of the fixed number of frequency bands and fixed processing parameters, and can better match the individual hearing status according to the characteristics of random sounds.

Description

Technical field [0001] The present invention relates to the field of audiology, particularly to an output sound variable frequency hearing aid device and a method of application thereof. Background [0002] Because the human ear is long-term "open", the external sound will directly enter regardless of the strength or weakness, at this time it is necessary to rely on the middle ear function and the inner ear function to "resist" the strong sound, reduce the introduction of loud sound, and thus protect the ear. However, if the human ear suffers hearing loss, this ability to regulate will become worse, and strong voices will also "unscrupulously" pour into the "human ear hearing system", resulting in further hearing loss. However, hearing loss has become more common and severe, with data released by the World Health Organization showing that 1.1 billion adolescents worldwide are at risk of hearing loss due to the use of headphones. This kind of hearing loss is generally caused by t...

Obviously, this method of amplifying sound is easy to "get out of control" in actual use, because the external sound is a random compound sound, and the sound components are complex and changeable. Simply put, random sounds must contain different frequencies and different sounds. Strong high-intensity sound, and the hearing aid uses its own microphone to pick up these sounds, it will not make a selection, it will only receive all of them, and then pass them to the processor, and then output them from the speaker

On the one hand, this amplification process will cause the sound transmitted to the user's ears to be unclear, causing users to often complain that they can't hear clearly. On the other hand, it is prone to over-amplification, and long-term use will further damage the user's hearing. , which is a common problem with conventional hearing aids

[0004] At present, some high-end hearing aid brands have launched some hearing aids with multi-channel processors, which can divide the common frequency of human ears from 125 to 8000 Hz into multiple frequency bands. The hearing aid fitter can independently set each frequency band according to the individual hearing loss status (audiogram). Gain, compression ratio, etc., so that the sound of this frequency band entering the ear will be processed according to the set gain. However, these hearing aids are expensive, and the division of frequency bands is fixed. It is set at the factory and cannot be changed later. Dealing with random sounds is still a big difficulty
