- Active noise control - Active noise control (ANC) (also known as noise cancellation, active noise reduction (ANR) or antinoise) is a method for reducing unwanted sound.
- Sound masking - Sound masking is the addition of natural or artificial sound (more commonly though less-accurately known as "white noise" or "pink noise") into an environment to "mask" or cover-up unwanted sound by using Auditory masking. This is in contrast to the technique of Active noise control.
