Problems solved by technology

For the popular open-ear hearing aids at this stage, because the microphone of the hearing aid is very close to the speaker, it not only amplifies the input signal, but also has a feedback loop from the speaker to the microphone; when both amplification and feedback appear in a system Positive feedback phenomenon may occur at times, which will lead to system instability, which is reflected in digital hearing aids. No matter what kind of echo feedback suppression method is used, the howling phenomenon cannot be completely eliminated

Abstract

The invention relates to a bluetooth hearing aid with voice input directivity. The bluetooth hearing aid comprises a message receiving module, a message passing-on module and a bluetooth network, wherein the message receiving module is connected with the message passing-on module through the bluetooth network; and the message receiving module performs directivity microphone information processing on acquired environmental voice and then transmits the acquired environmental voice to the message passing-on module through the bluetooth network. Compared with the prior art, the bluetooth hearing aid has the advantages of effectively improving the hearing effect of users; manually setting the voice input directivity according to the users in different environments and the like.

Description

technical field [0001] The invention relates to a hearing aid, in particular to a bluetooth hearing aid with directional sound input. Background technique [0002] In real life, most elderly people will experience hearing loss with age, some are congenital deaf patients, and some people have hearing loss due to acquired drugs, accidental injury, long-term strong noise and other factors. For patients with hearing impairment, hearing aids can be used to improve hearing. [0003] There are three types of hearing aids: traditional analog hearing aids, digitally encoded hearing aids, and all-digital hearing aids. Regardless of the type of hearing aid, it generally consists of three parts: a microphone, an amplifier, and a receiver. According to the shape, it is divided into box type, behind-the-ear type, in-ear type, glasses type and bone conduction hearing aid. The first four methods are to collect the ambient sound through the receiver, then process and amplify it by analog ...
