Active vs. Passive: Cutting Through the Noise When it comes to noise cancellation, two terms are often used interchangeably but have distinct meanings: active noise cancellation (ANC) and passive isolation.
Both technologies aim to reduce ambient noise and improve audio fidelity, but they differ significantly in their approaches.
Understanding Active Noise Cancellation (ANC) Technology Active noise cancellation relies on a microphone that captures ambient noise, which is then inverted and sent through an amplifier to cancel out the sound waves.
