The Redmi Buds 6 features ENC call noise cancellation and ANC technology.
For your reference, the differences between ENC and ANC are as follows:
Both ENC and ANC aim to suppress environmental noise, however, the benefit parties are different.
1. ENC (Environmental Noise Cancellation) optimizes audio signal processing algorithms to introduce additional processing steps between audio input and output. This reduces the impact of environmental noise on audio quality, enhancing call quality and audio clarity. The effectiveness of noise cancellation requires acoustic validation;
2. ANC (Active Noise Control) works by using microphones to collect external noise, then transforms it systematically into an inverted sound wave that is added to the output. The final sound coming into the human ear is the ambient noise + the inverted ambient noise. The superposition of these two noises results in a perceived reduction of noise, which benefits you. In contrast, cVc noise cancellation benefits the other party on the call.
