Active Noise Cancellation
A technology that uses microphones to capture ambient noise and generates inverse-phase sound waves in real time to cancel it out. Widely applied in headphones and other audio devices, it significantly reduces the level of external noise perceived by the user.
Core Facts
Timeline (last 90 days)
Budget noise-cancelling headphones generally refer to products priced around $100 that can deliver acceptable ANC performance.
High-end headphones are typically equipped with both feedforward and feedback microphone arrays: the feedforward microphone captures noise on the outer side of the ear cup, while the feedback microphone monitors residual noise on the inner side
Active noise cancellation technology is moving down from high-end products to more price segments, becoming a standard feature.
AirPods 5 introduces Active Noise Cancellation (ANC) technology to the standard AirPods product line for the first time.
Previously, active noise cancellation had been an exclusive feature of the AirPods Pro series.
Active noise cancellation coming to the standard AirPods may redefine the feature baseline for entry-level true wireless earphones.
All Facts (7)
Active Noise Cancellation (ANC) technology captures ambient noise through built-in microphones and uses a DSP to generate an inverted sound wave in real time that cancels the noise through superposition, a principle known as destructive interference.
