We often hear about noise-canceling headphones.Active Noise Cancelling Headphones，What are the current active noise reduction in the headset market?


Mainly ANC, ENC noise reduction technology. The following briefly introduces the difference between these two noise reduction modes:


1. ANC noise reduction
The working principle of ANC noise reduction is that the microphone collects external environmental noise, and then the system transforms it into an inverted sound wave and adds it to the speaker. The final sound heard by the human ear is: environmental noise + inverted environmental noise, two kinds of noise Superimpose, so as to realize the reduction of sensory noise, and the beneficiary is oneself. ANC active noise reduction can be divided into feedforward active noise reduction (with more headphone applications), feedback active noise reduction and hybrid active noise reduction. Feedback type is easy to cause howling.


2. ENC noise reduction technology
ENC uses a dual-microphone array to accurately calculate the direction of the caller's speech, which protects the target voice in the main direction while removing various interference noises in the environment. ENC technology can effectively suppress 90% of the reverse environmental noise, thereby reducing the environmental noise by up to 35dB, allowing gamers to communicate more freely.
