Active noise control

Active noise control (ANC), also known as active noise cancellation, is a technology used to reduce unwanted ambient sounds. It works by using microphones to pick up sound waves and generating a counteracting sound wave that is played through speakers or headphones. The principle behind ANC is based on destructive interference, where the opposing sound waves effectively cancel each other out. ### Key Components of Active Noise Control: 1. **Microphones**: These capture the ambient sound.
