, the (Swedish and Danish Øresund) Strait dividing SW Sweden from Denmark and linking the Kattegat strait and the Baltic Sea; length 113 km/70 mi; width between 5–60 km/3–37 mi.

Physiological sensation received by the ear, originating in a vibration that communicates itself as a pressure variation in the air and travels in every direction, spreading out as an expanding sphere. All sound waves in air travel with a speed dependent on the temperature; under ordinary conditions, this is about 330 m/1,070 ft per second. The pitch of the sound depends on the number of vibrations imposed on the air per second, but the speed is unaffected. The loudness of a sound is dependent primarily on the amplitude of the vibration of the air.
The lowest note audible to a human being has a frequency of about 20 hertz (vibrations per second), and the highest one of about 15,000 Hz; the lower limit of this range varies little with the person's age, but the upper range falls steadily from adolescence onward.
1. The sudden occurrence of an audible event; SYN. noise.
2. The particular auditory effect produced by a given cause; or
3. The subjective sensation of hearing something; SYN. auditory sensation, noise.
4. Audible vibrations transmitted through the air (or other medium)
5. A large ocean inlet or deep bay

ETYM Old Eng. sounen, sownen, Old Fren. soner, suner, French sonner, from Latin sonare. Related to Sound a noise.
1. To make a certain noise or sound; SYN. go.
2. To give off a certain sound or sounds.
3. To cause to sound.
4. To announce by means of a sound.
5. To appear in a certain way.

In acoustics, the conversion of sound energy to heat energy when sound waves strike a surface. The process reduces the amplitude of each reflected sound wave (echo) and thus the degree to which reverberation takes place. Materials with good sound-absorbing properties are often fitted on walls and ceilings in buildings such as offices, factories, and concert halls in order to reduce or control sound levels.

The, Novel 1929 by US writer William Faulkner. The story of a declining Southern family is told from four points of view including those of the three sons: Benjy, an imbecile; Quentin, a Harvard student who commits suicide; and Jason, an egotistical materialist. Dealing with historical collapse and lost love, the novel is a moving and technically difficult work.

Concept that the speed of sound, or sonic speed (about 1,220 kph/760 mph at sea level), constitutes a speed limit to flight through the atmosphere, since a badly designed aircraft suffers severe buffeting at near sonic speed owing to the formation of shock waves. US test pilot Chuck Yeager first flew through the “barrier” in 1947 in a Bell X-1 rocket plane. Now, by careful design, such aircraft as Concorde can fly at supersonic speed with ease, though they create in their wake a sonic boom.
