Princip i primjena digitalne tehnologije obrade protiv šuta

Trenutno, treća generacija proizvoda protiv šuma u Kini koriste tehnologiju dinamičkog smanjenja buke (DNR) . DNR tehnologija postiže svrhu smanjenja buke dinamičkim prilagođavanjem izlaznog glasovnog prekidača promjenom glasovnih vrhova . Iako je jedno od simulacije, a to ima i simulacije, a to ima i simulacije, a to ima, a to ima i simulacije na ding-a, a to ima i simulacije noise. The noise reduction effect is more focused on low frequencies. Noise reduction is entirely achieved through hardware circuits, but it is rather troublesome to debug and maintain. Due to these problems, the extensive promotion and application of analog DNR noise reduction products have been restricted. With the rapid development of digital signal processing technology, products of digital anti-noise technology supported by digital signal processors and related algorithms are constantly emerging. It has replaced the DNR analog noise reduction technology product. Digital anti-noise technology applies modern digital signal processing (DSP) technology and its characteristics of high-speed real-time processing and operation, and uses corresponding software algorithms to process voice and noise in high-noise environments, na taj način dovršavajući funkciju glasovne komunikacije u okruženjima s visokim šumom .
