   en.wikipedia.org/wiki/Noise-cancelling_headphones

   Noise -cancelling headphones alongside a carry case. Noise-cancelling headphones are headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing . Noise cancellation makes it possible to listen to audio ...

5. Soundproofing - Wikipedia

   en.wikipedia.org/wiki/Soundproofing

   Soundproofing is any means of impeding sound propagation.There are several basic ways to reduce sound: increasing the distance between source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using active antinoise sound generators.

7. Adaptive noise cancelling - Wikipedia

   en.wikipedia.org/wiki/Adaptive_noise_cancelling

   Adaptive noise cancelling is an unorthodox signal processing technique that is highly effective in suppressing additive interference or noise corrupting a received target signal at the main or primary sensor in certain common situations where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated, that is, uncorrelated.
