He is best known for the development of what the media termed "The Silence Machine" which was covered in some press, [1] in New ...
Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Noise-cancelling headphones are headphones that suppress unwanted ambient sounds using active noise control (ANC). Active noise cancellation makes it possible to listen to audio content without raising the volume excessively. In an aviation environment, noise-cancelling headphones increase the signal-to-noise ratio significantly more than ...
Brown noise, also called red noise, is more intense at lower frequencies, which produces a deep, rumbling sound, says Harris — think more bass and less static than white noise.
Sonic boom – sharp bullwhip -cracking sound associated with high-frequency shockwaves caused by an object (in this case, the bullet) flying supersonically through the air. Mechanical noise generated by the internal moving parts of the firearm action. A silencer can affect only the noise generated by the muzzle blast.
Sep. 9—After the candidates have spent millions on attack ads, mailers and streaming videos on social media, the voters get to silence all that noise for at least a day by casting ballots in ...
The result of receiving total silence, especially for a prolonged period, has a number of unwanted effects on the listener, including the following: the listener may believe that the transmission has been lost, and therefore hang up prematurely; the speech may sound "choppy" (see noise gate) and difficult to understand
The exact definition is often a matter of both cultural norms and personal tastes. Noise is an important component of the sound of the human voice and all musical instruments, particularly in unpitched percussion instruments and electric guitars (using distortion). Electronic instruments create various colours of noise.
