Ocean acoustics
| Морской словарь |
Refers to the study of sound and its behavior in the sea. when underwater objects vibrate, they create a sound wave that alternately compresses and decompresses the water molecules. the speed of the wave is the rate at which the vibrations travel through the sea. because the mechanical properties of the mediums differ, sound moves faster in water (1500 meters/sec) than in air (about 340 meters/sec). it also travels faster in warm water than in cold. sound waves radiate in all directions away from the source, like ripples on the surface of a pond, and are detected as changes in pressure by the human ear, as well as by man-made sound receptors such as a hydrophone, or underwater microphone. see also oceanic sound channel, sound surveillance system, and sound fixing and ranging.

Acoustic attenuation log, английский
Acoustic axis, английский
Acoustic back-up control system, английский
Акустическая вспомогательная система управления (подводнш оборудованием)
Acoustic baffle, английский
Sonar arrays are extremely sensitive to underwater noise and have to be protected from propeller cavitation, wake disturbance, machinery noise, and other sounds generated by the vessel. to this end a sound-attenuating shield or baffle is placed between hull-mounted sonar and the propulsion system (see baffle zone).
Acoustic beacon, английский
Acoustic beam deflector, английский
Acoustic brid, английский
Underwater, английский
- Подводный
- Below the surface, submerged.
Vibrations, английский
Mechanical, английский
Properties, английский
- A dockable window that displays the properties that are set on the selected object. in most cases, the property values can be edited in the window.
- A ui element that users can click to display information about a selected object.
Directions, английский
- Directions for use (on a bottle of medicine, etc.) instructions showing how to use something and how much of it to use
- Раскреплённый связями в двух взаимно перпендикулярных направлениях
- In the maps application, instructions for how to get from one location to another, either driving or walking.
Hydrophone, английский
- A device for detecting submerged submarines by the sound of their engines or other noise emissions.
- Гидрофон
Microphone, английский
- Микрофон
- A device which converts sound waves into essentially equivalent electric waves; the sound waves move an element in the device which generates an electric voltage.
- A device that converts sound into an electrical signal. common microphones include cardioid, ribbon, stereo, omnidirectional and condenser.
- A device that converts sound waves into analog electrical signals. additional hardware can convert the microphone’s output into digital data that a computer can process; for example, to record multimedia documents or analyze the sound signal.
Surveillance, французский
|
Ocean convoy, английский
A convoy whose course lies generally beyond the continental shelf.
Obstructor, английский
In naval mine warfare, a device laid with the purpose of inhibiting or damaging mechanical minesweeping equipment.
