POW-R (Psychoacoustically Optimized Wordlength Reduction) is a set of commercial dithering and noise shaping algorithms used in digital audio bit-depth reduction.Developed by a consortium of four companies – The POW-R Consortium – the algorithms were first made available in 1999 in digital audio hardware products.
Compression is used to improve performance and clarity in public address systems, as an effect and to improve consistency in mixing and mastering. It is used on voice to reduce sibilance and in broadcasting and advertising to make an audio program stand out. It is an integral technology in some noise reduction systems.
There are many noise reduction algorithms in image processing. [35] In selecting a noise reduction algorithm, one must weigh several factors: the available computer power and time available: a digital camera must apply noise reduction in a fraction of a second using a tiny onboard CPU, while a desktop computer has much more power and time
The logo represents both the company and its noise reduction system. dbx is a family of noise reduction systems developed by the company of the same name.The most common implementations are dbx Type I and dbx Type II for analog tape recording and, less commonly, vinyl LPs.

Polaris had been showing interest in electric propulsion, producing an electric version of its Ranger Side-by-Side and more recently buying Global Electric Motorcars (GEM). As one publication put it, "This latest move likely signals the addition of clean and quiet drivetrains to ATVs and motorcycles under the global giant's brand umbrella ...
The wavelength in air of sinusoidal noise at approximately 800 Hz is double the distance of the average person's left ear to the right ear; [1] such a noise coming directly from the front will be easily reduced by an active system but coming from the side will tend to cancel at one ear while being reinforced at the other, making the noise ...
A Dolby noise-reduction system, or Dolby NR, is one of a series of noise reduction systems developed by Dolby Laboratories for use in analog audio tape recording. [1] The first was Dolby A, a professional broadband noise reduction system for recording studios that was first demonstrated in 1965, but the best-known is Dolby B (introduced in 1968), a sliding band system for the consumer market ...
