    Firearm Sound Suppression Nature and Measuring of Firearm Sounds Philip H. Dater, MD Instructor, LMO Training, Henderson, NV ©2014 P. Dater Antares Technologies, Inc Nature of Sound • Air in motion • Pressure variation the human ear can detect • Pressures measured in Pascals* • Threshold of human hearing: 20 µPascals (0 dB) • Sound is a form of overpressure *NOTE: 1 PSI = 6895 Pascal Decibels (Db) • Pressures in Pascals are unwieldy numbers • Decibels are a ratio of pressures (named after Alexander Graham Bell) dB = 10(log10(P1/P0)) where P0 is the reference pressure (20 µPa) and P1 is the measured pressure Example: doubling (or halving) of the pressure is a 3 dB change, changing the pressure by a factor of 10 is a 10 dB change or a factor of 100 a 20 dB change If 1 PSI = 6895 Pascal. How many PSI overpressure is a 170 dB gunshot? Firearm Sound Sources Firearm sound generated by 1. Sudden release of hot, high pressure propelling gases in bore, and 2. Sound of bullet in flight (ballistic crack/sonic boom) which is generated outside the weapon system and cannot be addressed by a suppressor Firearm Sound Character Sound diminishes by inverse square law as observer moves away from source.

  • Design Sketch
    CONSTITUTION ARMS™ 12 Hoffman Street Maplewood, NJ 07040-1114 (973) 378-8011 www.constitutionarms.com Specification An ergonomically novel self-defense firearm intended for seniors, disabled and others with limited manual dexterity or hand strength. ATF classified as standard pistol, not “Any Other Weapon” (AOW) under the National Firearms Act (NFA). Page 1 Rev. 3/28/16 Palm Pistol ® Patents US7905042, D628259 Specification Introduction The Palm Pistol® is an ergonomically novel self-defensive firearm that uses the thumb for striker/firing pin release instead of the index finger. It is both ambidextrous and bilaterally symmetrical about its longitudinal axis rendering it functionally independent of the users hand dominance or bilateral orientation. It has no iron sights thus rendering eye dominance and sight alignment immaterial. The Palm Pistol® has 10 safety features, including three independent safeties that must be activated by the shooter using three different fingers before the pistol can be fired. Therefore, the action of the Palm Pistol® is not comparable to other single action handguns. Design Considerations One of the two principal factors of inaccurate fire is lateral muzzle drift induced during trigger squeeze.1 Use of the thumb for releasing the firing pin mitigates this problem. Also, the slim profile presents the ability to readily conceal the firearm without imprinting. There are no external moving parts which permit it to be fired from within a pocket or other clothing without the possibility of jamming on fabric. The design incorporates a latch safety, striker block, disengaged sear stop, cocked striker indicator, loaded chamber indicator, hand guard and grip assist ramp.

  • Glossary of Firearm Terminology
    VIRGINIA GUN COLLECTORS ASSOCIATION GLOSSARY OF FIREARMS COLLECTING TERMS Marc Gorelick VGCA A ACCOUTREMENT - Equipment carried by soldiers on the outside of their uniform, such as belts, ammunition pouches, bayonet scabbards, or canteens, but not weapons. ACCURIZE or ACCURIZING - The process of altering a firearm to improve its accuracy. ACTION - The mechanism and method that manipulates, loads, locks, extracts and ejects cartridges and/or seals the breech. Actions are broadly classified as either manual or self-loading and are generally categorized by the type of mechanism used. Manual actions are single shot or repeater. Single shot actions include dropping block (tilting or falling) rolling block, break, hinged (such as a trapdoor), and bolt. Repeater actions include revolver, bolt (turn-bolt or strait-pull), lever, pump and slide. Self-loading actions are semiautomatic or automatic. ADJUSTABLE SIGHT - A firearm sight that can be adjusted for windage and/or elevation so that the shooter’s point of aim and the projectile’s point of impact coincide at the target. Only the rear sight is adjustable on a majority of firearms, but front sights may also be adjustable. AIR CHAMBER (See LIGHTENING GROOVE) – A 19th century U.S. Ordnance Department the term for a groove cut out of the inside of a rifle’s wooden forend or a carbine’s forearm in order to make the firearm lighter.

  • Glossary 2311
    GLOSSARY 2311 GLOSSARY,GLOSSARY cont. GLOSSARY 1989 BUSH BAN Refers to the U.S. Federal executive branch study and resulting regulations which banned the importation of firearms which did not meet sporting criteria , i.e. certain paramilitary semi- auto only rifles and shotguns. The study was undertaken in response to the Stockton, CA tragedy in which an AK-47 type rifle was criminally used by a so-called mass murderer. The Federal regulation, U.S.C. Title 18, Section 922r, applies to imported firearms and to firearms assembled in the U.S. using imported components. It is important to note that even though the Assault Weapon Ban (which applied to U.S. manufactured firearms, not imports) has expired, Section 922r remains in effect, and has the force of U.S. Federal law, regardless of its executive branch origin as opposed to U.S. Senate and House of Representatives legislation. Also see Section 922r. 5R Five groove rifling developed in Russia. Instead of conventional six groove rifling with opposing lands and sharp edged transitions between lands and grooves, 5R lands oppose grooves and the sides of lands are cut at a sixty-five degree angle. Claimed benefits are: decreased bullet deformation, less jacket fouling, increased velocity, and greater accuracy. A1 STYLE Refers to an AR style rifle in A1 configuration, or A1 specific components (triangular handguard, short fixed buttstock, receiver with integral carry handle, four slot bird cage flash hider, smooth pistol grip, rear flip sight with short and long range apertures, lighter weight 1:14 twist barrel). A2 STYLE Refers to an AR style rifle in A2 configuration, or A2 specific components (circular bi-lateral handguard, longer fixed buttstock, receiver with integral carry handle and spent case deflector, five slot bird cage flash hider, finger rib pistol grip, windage and elevation adjustable rear flip sight with small day and large low light apertures, heavier weight 1:7 twist barrel).
