What would an American call the silencer on his car
"most countries, silencers are regulated along with firearms. Some jurisdictions allow, and even mandate, the sporting use of silencers, to reduce the risk of hearing loss and decrease noise pollution, while other governments ban them for civilian use. American inventor Hiram Percy Maxim, son of Maxim gun inventor Hiram Stevens Maxim and co-founder of the ARRL, is usually credited with inventing and selling the first commercially successful silencer around 1902, receiving a patent for it on March 30, 1909. Maxim gave his device the trademarked name ""Maxim Silencer"", and they were regularly advertised in sporting goods magazines. The muffler for"
"Silencer (firearms) A silencer, suppressor, sound suppressor, or sound moderator is a muzzle device that reduces the sound intensity and muzzle flash when a firearm or air gun is discharged. It can be a detachable accessory to, or integral part of, the muzzle or barrel. A typical silencer is a metal cylinder with internal sound baffles that slow and cool the escaping propellant gas, which decreases both sound volume and muzzle blast. A flash suppressor, on the other hand, specifically cools or disperses burning gases typically exiting from the muzzle of a carbine-length weapon, without reference to sound reduction. In"
"Firearms Act (NFA) of 1934 defined silencers and established regulations limiting their sale and ownership. Both the US Department of Justice and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) use the term ""silencer"". Hiram Percy Maxim, the original inventor of the device, marketed them as ""Maxim Silencers"". The earliest use of the term ""suppressor"" to refer to firearm noise reduction is in US Patent 4530417, July 23, 1985 ""A suppressor for reducing the muzzle blast of firearms or the like."" In UK English, ""silencer"" is the common term for either a motor vehicle muffler or for a gun"
"Muffler A muffler (silencer in British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine. The US Patent for an ""Exhaust muffler for engines"" was awarded to Milton O. Reeves and Marshall T. Reeves of Columbus, Indiana of the Reeves Pulley Company on 11 May 1897. US Patent Office application № 582485 states that they ""have invented certain new and useful Improvements in Exhaust-Mufflers for engines"". Mufflers are installed within the exhaust system of most internal combustion engines. The muffler is engineered as an acoustic device to reduce the loudness of the"
"primarily protecting the hearing of shooters and people in the vicinity, and to debunk the perceived myth in popular television, film and video game media that silencers are so effective that gunshot sounds can go totally unnoticed, such as by people in the next room of a building. In 2014, the ASA changed its name to American Suppressor Association ""in a continuing effort to dispel myths about suppressors"". Gun control advocates have said that changing the name from ""silencer"" to ""suppressor"" is semantic propaganda similar to the efforts to avoid terms like ""assault rifle"" or ""assault weapon"" in favor of"
"that had such a quiet report, although this is somewhat uncommon. Properly evaluating the sound generated by a firearm can only be done using a decibel meter in conjunction with a frequency spectrum analyzer during live tests. The silencer is typically a hollow metal tube manufactured from steel, aluminum, or titanium and contains expansion chambers. This device, typically cylindrical in shape, attaches to the muzzle of a pistol, submachine gun, or rifle. Some ""can""-type silencers (so-called as they often resemble a beverage can), may be detached by the user and attached to a different firearm. Another type is the ""integral"""
"signal to pass. The term ""windshield"" is used generally throughout North America. The term ""windscreen"" is the usual term in the British Isles and Australasia for all vehicles. In the US ""windscreen"" refers to the mesh or foam placed over a microphone to minimize wind noise, while a ""windshield"" refers to the front window of a car. In the UK, the terms are reversed, although generally, the foam screen is referred to as a microphone shield, and not a windshield. Sports or racing cars would sometimes have aero screens, which were small semi-circular or rectangular windshields. These were often mounted"
"silencer. ""Sound moderator"" has been used in UK English for silencers on high-powered rifles used for hunting or at ranges. The Oxford, American Heritage, and other dictionaries apply the term ""suppressor"" to such contexts as electromagnetic shielding devices, genetics, and censorship, but not firearms. These dictionaries define both ""silencer"" and ""suppressor"" as essentially equivalent and interchangeable, neither applying exclusively or primarily to sound, and both being applicable as much to complete and total quiet or to partial reduction of sound. In 2011, the US National Rifle Association began a campaign to increase the civilian use of silencers for hunting and"
"Senate to implement the use of textalyzers. Textalyzer A textalyzer is a proposed device that would act as a breathalyzer for text messaging. The device has been promoted as a means of reducing distracted driving. The device would be used by police officers who suspect that a driver has been texting while driving using similar procedures currently in place for drivers suspected of driving under the influence. The device would be connected to the driver's mobile phone and would scan the phone for calls, e-mails, or text messages sent when the driver would have been operating the vehicle. In 2016,"
"Twilight Sentinel On an automobile, Twilight Sentinel is a device on General Motors' cars that senses outside light and turns the exterior lights on and off depending on lighting conditions. In addition, Twilight Sentinel also allows the driver to set a timer (located with the headlight switch) that delays shutting off the headlights for a specified time period, usually up to three minutes. The driver can park the vehicle, shut off the car's engine and exit the automobile after dark, then use the headlights to light the path into a nearby building, such as a house, before the system shuts"
"suppressor, which typically consists of an expansion chamber or chambers surrounding the barrel. The barrel has openings or ""ports"" which bleed off gases into the chambers. This type of silencer is part of the firearm (thus the term ""integral""), and maintenance of the suppressor requires that the firearm be at least partially disassembled. Both types of silencers reduce noise by allowing the rapidly expanding gases from the firing of the cartridge to be decelerated and cooled through a series of hollow chambers. The trapped gas exits the suppressor over a longer period of time and at a greatly reduced velocity,"
"beyond 50 feet, as does Fairbanks, AK. Rhode Island specifically addresses low frequency sound that can be heard 20 feet from a closed vehicle or 100 feet otherwise. Salt Lake County Health Department, UT considers the sound a violation if it is ""plainly audible"" on a common carrier. Austin, TX states it must not be audible at 30 feet. This provision is a ""subjective emission"" control with only an operational time limit. Los Angeles, CA () requires silencing in 5 minutes. New York City, NY (Section 24.221(d)) requires automatic shut-off after 10 minutes and a prominent display of the local"
"Cone of Silence (Get Smart) The Cone of Silence is one of many recurring joke devices from ""Get Smart"", an American comedy television series of the 1960s about an inept spy. The essence of the joke is that the apparatus, designed for secret conversations, makes it impossible for those inside the device – and easy for those outside the device – to hear the conversation. The end result being neither secret nor communication. In popular culture, ""cone of silence"" is a slang phrase meaning that the speaker wishes to keep the indicated information secret and that the conversation should not"
"friendlier-sounding language like ""modern sporting rifle"", while gun rights advocates make essentially the opposite argument, and also that the widespread term ""silencer"" reflects technical ignorance and is poorly defined. Gun rights advocates and gun media generally say that the word ""silencer"" is defined as meaning ""total"" silence, while ""suppressor"" is defined as only meaning decreased sound intensity. When a firearm is discharged, there are three ways sound is produced. Part of it can be managed; however, some of it is beyond the ability of the operator or manufacturers to eliminate. In order of importance, the three ways a firearm generates"
"generate attention in high-noise environments like ""dense, urban traffic"". In addition, the siren's low thumping sound often causes bodily vibrations in persons who are near to it. The Rumbler is about 10 decibels quieter than a standard emergency vehicle siren and is generally activated in eight-second bursts by depressing the horn in a Rumbler-equipped vehicle. The Rumbler was developed by Federal Signal Corporation as an ""intersection clearing device"". It was initially tested by the New York Police Department in 2007. According to Noise Off, a noise pollution advocacy group, more than 100 U.S. police departments had deployed the siren by"
"Immobiliser An immobiliser or immobilizer is an electronic security device fitted to an automobile that prevents the engine from running unless the correct transponder car key (or other token) is present. This prevents the car from being ""hot wired"" after entry has been achieved and thus reduces motor vehicle theft. Research shows that the uniform application of immobilisers reduced the rate of car theft by 40%. The electric immobilizer/alarm system was invented by St. George Evans and Edward Birkenbuel and patented in 1919. They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when"
"slow and increase the pressure of the air. Early automobile intake systems were simple air inlets connected directly to carburetors. The first air filter was implemented on the 1915 Packard Twin Six. The modern automobile air intake system has three main parts, an air filter, mass flow sensor, and throttle body. Some modern intake systems can be highly complex, and often include specially-designed intake manifolds to optimally distribute air and air/fuel mixture to each cylinder. Many cars today now include a silencer to minimize the noise entering the cabin. Silencers impede air flow and create turbulence which reduce total power,"
"is designed to mitigate. Some aftermarket mufflers claim to increase engine output and/or reduce fuel consumption by dint of reduced back pressure. This usually entails less noise reduction (i.e., more noise). The legality of altering a motor vehicle's original equipment exhaust system varies by jurisdiction; in many developed countries such as the United States, Canada, and Australia, such modifications are highly regulated or strictly prohibited. Aftermarket mufflers usually alter the way vehicle performs due to back pressure decrease. Muffler A muffler (silencer in British English) is a device for reducing the noise emitted by the exhaust of an internal combustion"
"Sleeper (car) A sleeper (US English) or Q-car (British English) is a car that has high performance and an unassuming exterior. Sleeper cars are so called because their exterior looks similar or identical to a standard or economy-class car. In some cases the car appears worse due to seeming neglect on the owner's part, typically referred to as ""all go and no show"". While appearing to be a standard or neglected car, internally they are modified to have higher performance levels. The American nomenclature comes from the term sleeper agent, while the British term derives from the Q-ships used by"
"name came from the Greek work ""klaxo"" meaning ""shriek"" which described its sound. At the January 1908 Importers' Automobile Salon in Madison Square Garden New York, mayor George B. McClellan Jr. was reported to have used one to make sure he had the loudest car in the city. (Thomas Edison is said to have remarked that Miller had invented the Klaxon to deafen people so they would have to wear his Acousticon.) Hutchison himself had a limousine custom-built in May 1908 to showcase the latest in automotive electrical technology. The Witherbee Igniter Company installed storage batteries that could be recharged"
"brings the vehicle to a stop, and selects reverse. As that selection is made, some mechanism in the transmission stops the input shaft. Both gears are stopped and the idler can be inserted between them. There is a clear description of such a mechanism in the Honda Civic 1996–1998 Service Manual, which refers to it as a ""noise reduction system"": A reverse gear implemented this way makes a loud whining sound, which is not normally heard in the forward gears. The teeth on the forward gears of most consumer automobiles are helically cut. When helical gears rotate, there is constant"
"of noise. Local and state authorities have set up checkpoints on high-traffic trails, checking for excessively loud systems and issuing citations. Typically these systems are installed on two-stroke powered machines (giving the distinctive ""braap"" sound); however, in recent years aftermarket companies have released silencers for four-stroke models as well. Since the invention of snowmobiles, isolated communities of northern North America have always had a demand for them. However, the early snowmobiles designs were not economical or functional enough for the harsh environment of northern North America. Joseph-Armand Bombardier started producing the Ski-Doo in 1959 at the request of a priest."
"United States, improvised silencers are governed by the same laws as manufactured ones. Functionally, a suppressor is meant to diminish the report of a discharged round, or make its sound unrecognizable. Other sounds emanating from the weapon remain unchanged. Even subsonic bullets make distinct sounds by their passage through the air and striking targets, and supersonic bullets produce a small sonic boom, resulting in a ""ballistic crack"". Semi-automatic and fully automatic firearms also make distinct noises as their actions cycle, ejecting the fired cartridge case, and loading a new round. Aside from reductions in volume, suppressors tend to alter the"
"Scraper (car) A scraper is an informal term to describe a modified American-made luxury/family car, usually a General Motors model from the 1980s to current vehicles, typically enhanced with after-market rims. Scrapers are popular in the San Francisco Bay Area of Northern California, usually associated with the hyphy music and lifestyle movement. An example of hyphy is shown in the E-40 lyrics ""sittin' in my scraper watching Oakland gone wild"". A scraper is a general description and can refer to a number of different model cars. Popular models include the Buick Regal and LeSabre, Pontiac Bonneville, Buick Century, Oldsmobile Delta"
"One Square Inch of Silence One Square Inch of Silence is a noise control project symbolized by a small red stone symbolically placed in Hoh Rainforest at Olympic National Park in 2005 by author and sound recording specialist Gordon Hempton. The stone's location has been called ""the quietest place in the United States"". According to commercial pilot Philip Greenspun, some airlines have voluntarily rerouted flights to avoid inducing noise pollution at the square inch. Hempton has formed a foundation to prevent jet aircraft noise in Olympic National Park and other parks. Hempton's works, including One Square Inch of Silence, were"
"imposed by the U.S. Government. One unique feature of the car was its phonograph-based voice warning system. Warnings like those for a door being open, etc. would be relayed through the mini phonograph and played for the driver to hear. A common thing to hear would be, ""door is open, key is in ignition."" 1981 models were the first 'talking car' sold in the US and offered only one voice warning, a female voice reminding the driver to ""please turn off the lights"". In the fall of 1984, the first front-wheel drive Maxima (based on the Bluebird U11) was introduced"
"sound other than the horn, or some usage of the horn itself. A typical setup on cars is to have the horn or other sound chirp twice to signify that the car has been unlocked, and chirp once to indicate the car has been locked. For example, Toyota, Scion, and Lexus use a chirp system to signify the car being locked/unlocked. While two beeps means that driver's door is unlocked, four beeps means all doors are unlocked. One long beep is for the trunk or power tailgate. One short beep signifies that the car is locked and alarm is set."
"Rumbler, it is a siren that emits a low frequency sound which can be felt. Motorists that may have loud music playing in their car, for example, may not hear the audible siren of a police car behind them, but will feel the vibrations of the Rumbler. The feeling is that of standing next to a large speaker with pumped bass. Police officers' additional equipment may include: The installation of this equipment in a car partially transforms it into a desk. Police officers use their car to fill out different forms, print documents, type on a computer or a console,"

Used for privacy, the field does not visually obscure lip movement. Herbert had previously mentioned the cone of silence, on a much smaller scale, in his 1955 short story ""Cease Fire"". The larger, plastic version of the ""Cone of Silence"", appeared in the pilot episode of ""Get Smart"", entitled ""Mr. Big"", which aired on September 18, 1965. Mel Brooks and Buck Henry,"
"Silencers vary greatly in size and efficiency. One disposable type developed in the 1980s by the U.S. Navy for 9×19mm pistols was long and in outside diameter, and was designed for six shots with standard ammunition or up to thirty shots with subsonic (slower than the speed of sound) ammunition. In contrast, one suppressor designed for rifles firing the powerful .50 caliber (BMG) cartridge is long and in diameter. Two ancillary advantages to the silencer are recoil reduction and flash suppression. Muzzle flash is reduced by both being contained in the suppressor and through the arresting of unburned powder that"

Bystanders in the room could often hear them better, and sometimes relay messages back and forth. The Cone of Silence was the idea of Buck Henry, though it was preceded in an episode of the syndicated television show ""Science Fiction Theatre"" titled ""Barrier of Silence"", written by Lou Huston, that first aired on September 3, 1955, ten years ahead of ""Get Smart"". The car that Smart is seen driving most frequently is a red 1965 Sunbeam Tiger two-seat roadster."

For the 2015 Ford Mustang EcoBoost, an ""Active Noise Control"" system was developed that amplifies the engine sound through the car speakers. A similar system is used in the F-150 pickup truck. Volkswagen uses a Soundaktor, a special speaker to play sounds in cars such as the Golf GTi and Beetle Turbo. BMW plays a recorded sample of its motors through the car speakers, using a different samples according to the engine’s load and power. In 1904, well"
"Detuner (engine) Detuner is a generic term for a jet engine test cell exhaust system muffler. Aircraft jet engine testing facilities typically require a means to vent and dampen the engine exhaust. The engine exhaust flow is ""augmented"" with a relatively large flow of cooling air induced by a Venturi effect into the exhaust silencing system, so the exhaust muffler is generally referred to as an ""augmenter tube,"" or ""detuner"" (UK).
