Speed of sound
|
The speed that a sound wave travels through a given medium. the speed of sound depends on several properties of the medium, most importantly its density. in the atmosphere, the speed changes with air temperature and pressure. at standard sea-level pressure (101.3 kpa), the speed of sound is 340 metres per

Sound attenuation, английский
- Sound proofing a wall or subfloor, generally with fiberglass insulation.
- The reduction in the intensity or in the sound pressure level of sound which is transmitted from one point to another. also
Sound attenuator, английский
In ductwork, a device (usually prefabricated) especially designed to provide much greater sound attenuation than would be provided by an equal length of ductwork; the pressure drop through the device is greater than for an equal length of ductwork.

- 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.
Atmosphere, английский
- The envelope of gases that surround a planet`s surface held by the planet`s gravity. over the earth, the atmosphere is divided into several layers based on their properties. the most common layer designations are
- Атмосфера
- The ambient air, or thin elastic fluid which surrounds the globe, and gradually diminishing in gravity rises to an unknown height, yet by gravitation partakes of all its motions.
- [1] the envelope of air surrounding the globe. [2] a unit of pressure equal to 76 centimeters (29.9 inches) of mercury, or 1033.2 grams/sq. centimeter (2116.3 pounds/sq. foot). (cf. hydrosphere, lithosphere.)

Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.

- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).

- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
