Radio acoustic ranging... was a method for determining a ship's precise location at sea by detonating an explosive charge underwater near the ship, detecting the arrival of the underwater sound waves at remote locations, and radioing the time of arrival of the sound waves at the remote stations to the ship, allowing the ship's crew to true range multilateration to determine the ship's position.  4, fiche 1, Anglais, - radio%20acoustic%20ranging

While the SFCS has a number of features and capabilities designed to vastly improve target identification and hand-off among a number of operators, its core is a muzzle velocity sensor. The system sits on the Picatinny rail of any weapon and draws on a number of acoustic sensors to characterize how the weapon is performing between the time the primer of a round is struck and the bullet leaves the barrel.... Meteorological and other sensor inputs are fed into a ballistics computation that then gives a range azimuth correction to the operator. It helps the operator correct his aim point so that his probability of hit for second, third and fourth rounds is that much more accurate.  1, fiche 13, Anglais, - soldier%20fire%20control%20system

[The] B-2 Spirit originally started as Project Senior CJ and [was] later renamed as ATB(Advance Tactical Bomber). The B-2 uses four F-118 Turbofans.... The turbofan has intake and exhaust at the top of the aircraft to prevent ground control to spot them. The pilot and co-pilot are seated side by side in a zero-zero vertically ejecting ACES II seats.... a B-2 can get updates for GPS satellites to avoid ground firing while the pilot spots the target. Once the target is found, the pilot will turn on special radar, which only scan the target area and once spotted the B-2 will launch its nuclear ordnance or SRAM II missiles.... the B-2 provides the penetrating flexibility and effectiveness inherent in manned bombers. Its low-observable, or "stealth, "characteristics give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most-valued, and heavily defended targets. Its unrefueled range is approximately 6, 000 nautical miles(9, 600 kilometers). The B-2's low observability is derived from a combination of reduced infrared, acoustic, electromagnetic, visual and radar signatures.  2, fiche 19, Anglais, - advanced%20tactical%20bomber

Horns were first applied to earmolds in the late 1950s in the "Acoustic Modifier"--a short-canal, wide-bore mold. Enlarging a sound bore will enhance high frequencies passing through it; reducing it will reduce the high frequency components. The key to horn theory involved the change in bore diameter, not its shape. With the extended high frequency range of many of today's hearing aids, a horn of some type should be employed to preserve the performance and achieve a successful fitting. Probably the most popular style is the Libby Horn--a tapered, one-piece sound tube which is replaceable in the dispenser's office.  2, fiche 20, Anglais, - earmold%20with%20Libby%20horn
