The subsequent 143-page report (PB 211-015, available from NTIS) reviewed a series of actual handling tests designed to evaluate the handling and stability under extreme conditions; a review of national accident data compiled by insurance companies and traffic authorities for the cars in the test—and a review of related General Motors ...
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that suppresses the blast created when a gun (firearm or airgun) is discharged, thereby reducing the acoustic intensity of the muzzle report (sound of a gunshot) and jump, by modulating the speed and pressure of the propellant gas released from the ...
As the goal of accurizing a firearm is to improve its accuracy, the way accuracy is measured becomes important. A firearm used primarily as a hunting weapon will need to be accurate on the first shot from a cold, clean barrel, while one used for target shooting may be allowed fouling shots before the first shot for record is fired.
The Wikipedia argument for why suppressor is more "correct" is that silencers do not eliminate 100% of noise, but that is not how English works. The UK English term for muffler is silencer, with no regard for the obvious fact that car silencers/mufflers do not make cars "silent". Worse, any dictionary can confirm that "suppress" does not imply ...
Silencer (silver) and exhaust pipe on a Ducati motorcycle A silencer cut open to show the insulation, chambers and piping inside the shell. A muffler (North American and Australian English) [1] or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an ...
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
The National Transportation Safety Board has recommended that all new automobiles come equipped with technology meant to make speeding difficult or impossible, a move that comes after an accident ...
Test accuracy requires procedures that avoid secondary gunshot residue transfer from police officers onto subjects or items to be tested, and that avoid contamination in the laboratory. The two main groups of specialists currently active on gunshot residue analysis are the Scientific Working Group for Gunshot Residue (SWGGSR) based in USA and ...
