Artificial Noise
Artificial noise is a wave or vibration, audible, electromagnetic, or other signal, generated by a human source. Usage The purpose of generating artificial noise, whether intentional or not, may vary, depending on what is considered noise in a particular context. It can be used to experiment on a subject by controlling the frequency or amplitude of the artificial noise to ascertain how the subject interacts with external stimulation. For example, to test the sensitivity of a microphone noise-reducing filter, the test administrator could generate artificial noise in a laboratory setting to determine whether the microphone suppresses the noise (i.e. filters it out), or interprets the noise as something that is not noise (i.e. passes it through). In the context of urban dwellings or establishments, artificial noise might be called light pollution, or commuter traffic. In sport In the context of spectator sports, artificial noise is the use of artificial sound-making devices to sho ...

Signal Processing
Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing ''signals'', such as audio signal processing, sound, image processing, images, and scientific measurements. Signal processing techniques are used to optimize transmissions, Data storage, digital storage efficiency, correcting distorted signals, subjective video quality and to also detect or pinpoint components of interest in a measured signal. History According to Alan V. Oppenheim and Ronald W. Schafer, the principles of signal processing can be found in the classical numerical analysis techniques of the 17th century. They further state that the digital refinement of these techniques can be found in the digital control systems of the 1940s and 1950s. In 1948, Claude Shannon wrote the influential paper "A Mathematical Theory of Communication" which was published in the Bell System Technical Journal. The paper laid the groundwork for later development of information c ...

PET Film (biaxially Oriented)
BoPET (biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the best-known trade names are Mylar, Melinex, and Hostaphan. History BoPET film was developed in the mid-1950s,Izard, Emmette Farr"Production of polyethylene terephthalate" U.S. patent no. 2,534,028 (filed: 1948 May 13; issued: 1950 December 12). originally by DuPont, Imperial Chemical Industries (ICI), and Hoechst. In 1955 Eastman Kodak used Mylar as a support for photographic film and called it "ESTAR Base". The very thin and tough film allowed reels to be exposed on long-range U-2 reconnaissance flights.

Thunder Sticks
Thundersticks, sometimes known as bambams, are long, narrow plastic balloons that are used as promotional noise makers. The noise is created when two thundersticks are struck together. They are most often used at sporting events. Origin and popularity Thundersticks, known as ''makdae pungseon'' () in South Korea, were created by BalloonStix Korea and first used in 1994 at an LG Twins baseball game. They later gained popularity in North America when they were used by fans of the Anaheim Angels during the 2002 World Series. Today thundersticks are used by fans of many sports teams in order to show their support, serving a similar purpose as the Homer Hanky associated with the Minnesota Twins and the Terrible Towel associated with the Pittsburgh Steelers. Thundersticks have appeared around the world at many sporting events. They are regularly seen in baseball games in Taiwan, basketball games in the Philippines, and football matches throughout Europe, but sometimes under differe ...

Arena Football League (1987–2008)
The Arena Football League (AFL) was a professional arena football league in the United States. It was founded in 1986, but played its first official games in the 1987 season, making it the third longest-running professional football league in North America after the Canadian Football League (CFL) and the National Football League (NFL) until the AFL closed in 2019. The AFL played a formerly proprietary code known as arena football, a form of indoor American football played on a 66-by-28 yard field (about a quarter of the surface area of an NFL field), with rules encouraging offensive performance, resulting in a typically faster-paced and higher-scoring game compared to NFL games. The sport was invented in the early 1980s and patented by Jim Foster, a former executive of the United States Football League (USFL) and the NFL. Each of the league's 32 seasons culminated in the ArenaBowl, with the winner being crowned the league's champion for that season. From 2000 to 2009, the AF ...

Technical Foul
In basketball, a technical foul (colloquially known as a "T" or a "tech") is any infraction of the rules penalized as a foul which does not involve physical contact during the course of play between opposing players on the court, or is a foul by a non-player. The most common technical foul is for unsportsmanlike conduct. Technical fouls can be assessed against players, bench personnel, the entire team (often called a bench technical), or even the crowd. These fouls, and their penalties, are more serious than a personal foul, but not necessarily as serious as a flagrant foul (an ejectable offense in leagues below the National Basketball Association (NBA), and potentially so in the NBA). Technical fouls are handled slightly differently under international rules than under the rules used by the various competitions in the United States. First, illegal contact between players on the court is always a personal foul under international rules, whereas in the United States, such contact i ...

Spectator Sport
A spectator sport is a sport that is characterized by the presence of spectators, or watchers, at its competitions. Spectator sports may be professional sports or amateur sports. They often are distinguished from participant sports, which are more recreational. Most popular sports are both spectator and participant, for example association football, basketball, cricket, tennis, Rugby football, rugby, golf, Sport of athletics, athletics and volleyball. Less popular sports are mainly participant sports, for example hunting. The increasing broadcasting of sports events, along with media reporting can affect the number of people attending sports due to the ability to experience the sport without the need to physically attend and sometimes an increasingly enhanced experience including highlights, replays, commentary, statistics and analysis. Some sports are particularly known as "armchair sports" or "lounge room sports" due to the quality of the broadcasting experience in comparison ...
