ENC降噪 ENC(Environmental Noise Cancellation,环境降噪技术),能有效抑制90%的反向环境噪声,由此降低环境噪声最高可达35dB以上,让游戏玩家可以更加自由的语音沟通。通过双麦克风阵列,精准计算通话者说话的方位,在保护主方向目标语音的同时,去除环境中的各种干扰噪声。 DSP降噪 DSP是英文(digital signal processing)的简写。
The result is a small, low-cost highly effective solution for low/medium-frequency noise, producing successful commercial solutions across many applications; including for the home and office; the industrial workplace; and both the automotive and transportation industries. We actively reduce either from...
When we have a noise problem in our lives, the first thing we do is try to get rid of it. This is called passive noise reduction, and it involves insulating the room or your ears from the sound and is the typical method used in most soundproofing projects. Active noise cancellation is...
noise, and thereby generates the appropriate cancellation signal based on the results of this model. This signal is then transmitted to the speaker, which transforms this signal into a canceling sound. Because the control unit may not perfectly model engine noise, an error microphone is placed in...
