Noise (acoustic)

Acoustic noise is any sound in the acoustic domain, either deliberate (music, speech, etc.) or unintended. It is important to recognise that the term "noise" is also used to refer to other, non-audible forms, especially in electronics and in the radio/radar spectrum.

Environmental noise

Environmental noise is the comprehensive study of acoustic phenomena in the human environment which involve unwanted sound. The principal sources of environmental noise are surface motor vehicles, aircraft, trains and industrial sources. These noise sources expose millions of people to noise pollution that creates not only annoyance, but also significant health consequences such as elevated incidence of hearing loss and cardiovascular disease. There are a variety of mitigation strategies and controls available to reduce sound levels including source intensity reduction, land use planning strategies, noise barriers and sound baffles, time of day use regimens, vehicle operational controls and architectural acoustics design measures.

Noise (company)

Noise Inc. (株式会社ノイズ) is a video game development company that works in partnership with Nintendo, developing games for the Custom Robo series.

History

Noise was founded with a staff of 10 people on September 2, 1996 for the original purpose of developing games for PCs. A short time after, Noise became a part of Marigul Management, a company created by Nintendo and the Japanese telecommunications company Recruit for the purpose of enlisting smaller developers to make original games for the Nintendo 64.

The company’s first commercially published game, Custom Robo for the Nintendo 64, was released in Japan on December 9, 1999 and became a commercial success in Japan, prompting Nintendo to formally enter a publishing agreement with Noise. In 2006, Custom Robo was released in China for the iQue Player, making it the only Custom Robo title ever to be released there.

Their second released title was Custom Robo V2, which was released on November 10, 2000 and was also met with commercial success in Japan. They also released their first portable video game for the Game Boy Advance, Custom Robo GX, on July 26, 2002.

Noise (signal processing)

In signal processing, noise is a general term for unwanted (and, in general, unknown) modifications that a signal may suffer during capture, storage, transmission, processing, or conversion.

Sometimes the word is also used to mean signals that are random (unpredictable) and carry no useful information; even if they are not interfering with other signals or may have been introduced intentionally, as in comfort noise.

Noise reduction, the recovery of the original signal from the noise-corrupted one, is a very common goal in the design of signal processing systems, especially filters. The mathematical limits for noise removal are set by information theory, namely the Nyquist–Shannon sampling theorem.

Types of noise

Signal processing noise can be classified by its statistical properties (sometimes called the "color" of the noise) and by how it modifies the intended signal:

Template (file format)

The term document template when used in the context of file format refers to a common feature of many software applications that define a unique non-executable file format intended specifically for that particular application.

Template file formats are those whose file extension indicates that the file type is intended as a very high starting point from which to create other files.

These types of files are usually indicated on the File menu of the application:

For example, the word processing application Microsoft Word uses different file extensions for documents and templates: In Microsoft Word 2003 the file extension .dot is used to indicate a template, in Microsoft Word 2007 .dotx (in contrast to .doc, resp. .docx for a standard document).

In Adobe Dreamweaver the file extension .dwt is used to indicate a template.

Microsoft Word Templates

MS Word allows creating both layout and content templates. A layout template is a style guide for the file styles. It usually contains a chapter which explains how to use the styles within the documents. A content template is a document which provides a TOC. It might be modified to correspond to the user's needs.
