Problems solved by technology

This technique is different from the purpose of the present invention, and removing all sounds below a certain preset value may cause sound distortion
[0006] Prior art U.S. Patent No. 6,577,739 "Apparatus and methods for proportional audio compression and frequency shifting" compresses the sound signal at a certain ratio and provides it to the hearing-impaired person with hearing loss in a specific range. However, this technology is for the overall sound Doing compression will make the sound distorted seriously

Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0049] like figure 1 Shown is the overall schematic diagram of the hearing aid of the present invention.

[0050] The hearing aid 10 of the present invention includes a receiver 11 , a sound processing module 12 and a speaker 13 . The microphone 11 is used for receiving the input sound 20 from the sound source 80 , and after being processed by the sound processing module 12 , it is played by the speaker 13 . The receiver 11 can be any device that can receive sound, such as a microphone, and the speaker 13 can be any device that can broadcast sound, such as an earphone, but the present invention is not limited to the devices listed above. The sound processing module 12 is generally composed of a sound processing chip with a control circuit and an amplifier circuit; it can also be a solution c...

Abstract

The invention discloses a method for improving the accuracy of a sound heard by a hearing-impaired listener. The method comprises the following steps of: receiving an input sound, judging whether frequency correction is required by the input sound or not, and correcting the input sound into a modified input sound if the frequency correction is required by the input sound. The key of a judgment mode refers to judgment in the frequency and sound energy of the input sound. The input sound is changed into the modified input sound, so that the sound energy of low frequency can be improved.

Description

technical field [0001] The invention relates to a method and a hearing aid for increasing the correctness of a hearing-impaired person's hearing of a sound, in particular to a method for increasing the correctness of a hearing-impaired person's hearing of a sound by performing frequency correction on an input sound and a hearing aid. Background technique [0002] The development of hearing aids has a long history. The main concept is to amplify the sound to help the hearing-impaired hear the sound that they could not hear originally. In this way, the speaker does not need to deliberately amplify the sound to be heard by the hearing-impaired. But the sound that the hearing-impaired cannot hear has two characteristics: the frequency is too high and the intensity is too low. Sounds with these two characteristics are easily ignored by the hearing-impaired. For example, sounds such as "ㄗ", "ㄘ" and "ㄙ" in Zhuyin have such characteristics, so it is difficult for the hearing-impair...
