通话降噪技术，通过麦克风收集环境声音，与双咪降噪不同的原理是，双咪降噪

Call noise reduction technology, environmental sounds collected by the microphone, with dual microphone noise reduction is a different principle, by issuing dual-microphone noise reduction is the opposite of acoustic noise, noise elimination using the offset principle, but the principle is the elephant Sound by noise the collected ambient sound through the algorithm processing, identification acoustic noise, and then filter out the noise sound waves, the user needs to retain the call sound waves, allowing users to hear more pure sound without noise, noise reduction and better

Call noise reduction technology, through the microphone to collect ambient sound, unlike the principle of noise reduction is that the two meters noise reduction is by making the opposite sound waves to the noise, using the cancellation principle to eliminate noise, while the elephant sonar noise reduction principle is that the collected ambient sound is processed by algorithm, intelligently identify sound waves, and then filter out these noise sound waves, Retains the call sound waves that the user needs, so that the user hears a purer, noise-free sound and reduces noise better

Call noise reduction technology collects environment sound through microphone. Different from bimicro noise reduction, bimicro noise reduction is based on the principle of generating sound waves that are opposite to the noise, and using the principle of cancellation to eliminate the noise. The principle of elephant acoustics is to process the collected environment sound through algorithm, intelligently recognize the noise sound waves, and then filter out the noise sound waves to keep what users need Call sound wave, so that the user can hear more pure and noiseless sound, with better noise reduction effect<br>
