Hearing aid device with variable-frequency output sound and application method thereof

Abstract

The invention discloses a hearing aid device with variable-frequency output sound. The hearing aid device comprises an input port, a storage regulator, a processor and a plurality of loudspeakers, the input port, the storage regulator and the loudspeaker are all connected with the processor; the storage regulator may write patient audiogram and / or HLD data; the processor can be embedded with an algorithm with variable frequency band number and variable frequency width; and the input port is configured to input a sound signal; the processor is configured to receive a sound signal from the input port, change the number of frequency bands and bandwidth according to the sound signal and data in the storage regulator, and then output the sound signal by controlling the loudspeakers with different numbers; the processor can independently control the opening and closing of each loudspeaker. The invention further discloses an application method of the hearing aid device. The hearing aid device can control the number of frequency bands and the bandwidth, overcomes the defects of the number of fixed frequency bands and fixed processing parameters, and can better match the hearing state of an individual according to the characteristics of random sound.

Description

technical field [0001] The invention relates to the field of audiology, in particular to a hearing aid device with variable output sound frequency and an application method thereof. Background technique [0002] Since the human ear is "open" for a long time, the external sound will enter directly no matter how strong or weak it is. At this time, it is necessary to rely on the function of the middle ear and the inner ear to "resist" the strong sound, reduce the incoming of loud noise, and protect the ear. However, if hearing loss occurs in the human ear, this regulation ability will become poor, and strong sounds will also flood into the "human auditory system" "unscrupulously", leading to further hearing loss. However, hearing loss has become more common and serious. According to data released by the WHO (World Health Organization), 1.1 billion young people around the world are at risk of hearing loss due to the use of headphones. This kind of hearing loss is generally caus...

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
