What is the noise reduction technology of hearing AIDS?

Noise reduction technology is not a very new technology. Before it is applied to hearing AIDS, it is required to be applied in many fields, such as communication and machinery. As the name implies, noise reduction technology can distinguish noise from noisy speech signals and remove noise. Although the current signal processing technology is ever-changing, the noise reduction technology applied to hearing AIDS is very similar to these technologies. In the field of hearing AIDS, since the advent of hearing AIDS, as the pursuit goal of hearing aid researchers and manufacturers all over the world, how to better handle sound in noisy environment, so as to help hearing aid users obtain clearer speech signals, has always been a concern of all audiologists and hearing aid users. This is because the biggest problem of high-quality noise reduction is the understanding of language in various noise environments. Only by improving the acceptance of hearing AIDS by hearing aid wearers and increasing the wearing and using time of hearing AIDS can we provide the most basic observation conditions for the updating of hearing aid technology and provide more opportunities for clinical workers to understand the clinical application of new hearing aid technology, thus establishing a virtuous circle and constantly updating, verifying and updating hearing aid technology. However, unlike the general speech algorithm, the speech intensity algorithm applied to hearing AIDS must take into account the real-time performance and limited computation, while maintaining the integrity of the speech structure to the maximum extent. From another point of view, the progress of hearing aid noise reduction technology is only the continuous improvement and optimization of hardware and algorithms, and it is possible to find a balance between noise reduction performance and computational complexity, and tend to be optimized. At present, hearing aid users want to use the existing hearing aid noise reduction technology to help them get more voice signals in the complex and changeable daily life environment and communicate with people better. In addition to the directional microphone technology that has been repeatedly verified by experiments and clinics, the application of noise reduction in hearing AIDS is gradually improved with the expansion of chip memory and the improvement of computing power. At the same time, in order to understand the working principle of hearing aid noise reduction more deeply, we should pay attention to the working method and effectiveness of the noise reduction system installed inside the hearing aid to ensure effective application.
