2.前馈降噪麦克风会检测外部声波，随后，在你听到这些外部声波之前，耳机

2. The front feed noise reduction microphone detects external sound waves, and then, before you hear the external sound waves, the headset will be comparable with the anti-noise wave to cancel out, so feed the noise reduction achieved before;

2. The feed-forward noise-cancelling microphone detects external sound waves, and then, before you hear these external sound waves, the headset will offset them with the equivalent anti-noise waves, thus enabling the feed-forward noise reduction;

2. The feed-forward noise reduction microphone will detect the external sound waves, and then, before you hear these external sound waves, the headset will use the corresponding anti noise sound wave to cancel them, so as to realize the feed-forward noise reduction;<br>
