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 ...
In a noisy environment, both microphones receive noise at a similar level, but the primary mic receives the desired sounds more strongly. Thus if one signal is subtracted from the other (in the simplest sense, by connecting the microphones out of phase) much of the noise is canceled while the desired sound is retained.
The pipe which held the "collector head" (microphone) can be seen in front of the structure. An acoustic mirror is a passive device used to reflect and focus (concentrate) sound waves. Parabolic acoustic mirrors are widely used in parabolic microphones to pick up sound from great distances, employed in surveillance and reporting of outdoor ...
Unlike its predecessors, the QC25s can be used (without the noise cancelling function) while the battery is dead. Another change is the elimination of the Hi/Low switch which increased the input gain for low-output sources like MP3 players. In 2015, the QC25s won the What Hi-Fi? Sound and Vision annual award for "Best Noise Cancelling Headphones".
i-sleepPRO — This ambient sleep aid that has settings for "white noise" and "black noise"; the latter includes thumping bass music, dialogue from Tyler Perry sitcoms and the movie Friday, domestic arguments, and an old woman complaining about her foot pain. Jay Pharoah provides voice work for the device.
Adaptive feedback cancellation. Adaptive feedback cancellation is a common method of cancelling audio feedback in a variety of electro-acoustic systems such as digital hearing aids. The time varying acoustic feedback leakage paths can only be eliminated with adaptive feedback cancellation. When an electro-acoustic system with an adaptive ...
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 ...
A general-purpose throat mic used for two-way radio communications. A throat microphone, also called a laryngophone, is a type of contact microphone that absorbs vibrations directly from the wearer's throat by way of single or dual sensors worn against the neck. The sensors, called transducers, can pick up speech even in extremely noisy or ...
