What Are ENC and ANC?

There are several noise reduction capabilities in headphones, such as ANC, ENC, DSP, and CVC. The noise cancellation feature is critical to the earphone's functionality. One is to limit noise and avoid over-amplifying the volume, thus avoiding ear damage. The second step is to filter out background noise to enhance sound and call quality.

There are two types of noise reduction: passive and active noise reduction. The term "passive noise reduction" refers to noise reduction by physical means. Passive reduction uses physical characteristics like the tight earphone’s head beam and the earmuff cavity. Passive noise reduction is exceptionally decent at isolating high-frequency noises (human voices) and decreases noise by roughly 15-20 dB on average.

Active noise reduction refers to ANC, ENC, CVC, DSP, and other noise reduction features built inside headphones that help reduce noise. Of these four features, let’s take a look at ENC and ANC.


The Active Noise Cancellation (ANC) principle is that the microphone gathers external environmental noise, which is then transformed into an opposite sound wave and added to the speaker by the system. The ANC adds another noise to the environment, and the technology is designed to cancel the environmental noise. The feedback of this sound is environmental noise plus the inverse of the sound.


Environmental Noise Cancellation (ENC, or ambient noise reduction technology) can efficiently block 90% of reverse environmental noise, lowering ambient noise by more than 35 decibels and allowing speakers to speak more freely. The beneficiary of ENC is the other party of the call. The impact of environmental noise on the call is reduced through ENC so that the other party can hear a pure voice. The caller's speech position is evaluated correctly thanks to the dual sound source, which also protects the target speech in the primary direction and eliminates all types of background noise.

When comparing active noise cancellation versus environmental noise cancellation, it is important to remember that environmental noise cancellation can only eliminate sounds to a certain extent. Active noise cancellation, on the other hand, may reduce noise by up to 40 decibels.

The ANC and ENC headphones provide noise reduction in everyday activities, whether you are gaming, exercising, traveling, or playing music. But ENC headphones are more recommended, just like the following two noise cancelling Bluetooth headsets.
