2. Noise-cancelling headphones - Wikipedia

   en.wikipedia.org/wiki/Noise-cancelling_headphones

   Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control or ANC.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.

3. Active noise control - Wikipedia

   en.wikipedia.org/wiki/Active_noise_control

   The wavelength in air of sinusoidal noise at approximately 800 Hz is double the distance of the average person's left ear to the right ear; [1] such a noise coming directly from the front will be easily reduced by an active system but coming from the side will tend to cancel at one ear while being reinforced at the other, making the noise ...

4. In-ear monitor - Wikipedia

   This can potentially lead to increased sound exposure as it reduces the signal-to-noise ratio for the mix and causes the musician to increase the levels from the IEM. Active ambient IEMs use external microphones to reproduce the ambient sound in the mix that mimics the frequency response of the open ear and may sound more natural to the performer.

5. Adaptive feedback cancellation - Wikipedia

   en.wikipedia.org/wiki/Adaptive_feedback_cancellation

   Adaptive feedback cancellation originated during the evolution of the hearing aid. The hearing aid became digital, and as such feedback cancellation was needed. In 1980 a directional microphone was introduced in the digital hearing aid, and adaptive feedback cancellation was created to block external noise that the microphone picked up. Today ...

6. Noise-canceling microphone - Wikipedia

   en.wikipedia.org/wiki/Noise-canceling_microphone

   The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .

7. List of Bose headphones - Wikipedia

   In 2019, Bose released the Noise Cancelling Headphones 700, also known as the NCH 700, a new high-end product positioned above the QC 35. [13] [14]The headphones have a stainless steel band and are controlled using a mix of buttons and touch-sensitive areas on the cups.
