The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Adaptive noise cancelling. Adaptive noise cancelling is a 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 ...
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 ...

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.
Design. If you’re thinking the Beats Fit Pro look almost exactly like the Beats Studio Buds, you’re not wrong. This new model is a smidge larger and the angle of the tab that holds the on ...
