sound5 (sound)

a sounding-body when a current of air is continually forced through the mouthpiece past the lip; again, an inelastic body, as a card, may become a sounding-body if it receives a series of blows at regular intervals and in sufficiently rapid succe ion, as from the teeth of a revolving cog-wheel. The vibrations of the sounding body are conveyed to the ear by the intervening medium, which is usually the air, but may be any other gas, a liquid (as water), or an elastic solid. The presence of such a medium is e ential, for sound is not propagated in a vacuum. The vibrations of the sounding-body, as a tuning fork, produce in the medium a series of waves (see wave ) of condensation and rarefaction, which are propagated in all directions with a velocity depending upon the nature of the medium and its temperature-for example, the velocity of sound in air is about 1,090 feet per second at 32° F. (0°C.), and increases slightly as the temperature rises; in other gases the velocity varies inversely as the square root of the density; it is consequently nearly four times as great in hydrogen. In liquids the velocity is greater than in air-for water, somewhat more than four times as great. In solids the velocity varies very widely, being relatively small in inelastic substances like wax and lead, and very great (two to three miles per second) in wood and steel. Sound-waves may differ (1) in their wavelength-that is, in the number of vibrations per second; (2) in the amplitude of the motion of the particles forming them; and (3) in their form, as to whether they are sim Shak., Tit.

Brooke's apparatus is said to be the first by which soundings of over 2,000 fathoms were made and specimens of the bottom obtained.

In surg., to examine by means of a sound or probe, especially the bladder, in order to ascertain whether a stone is present or not. By a precious oyle Doctor Ru ell at the first applyed to it when he sounded it with probe (ere night) his tormenting paine was well a waged. Quoted in Capt . John Smith's Works, I. 179. 3. Figuratively, to try; examine; discover, or endeavor to discover, that which is concealed in tions, or are compound, and formed of several such series superimposed upon each other. Corresponding to these differences in the sound-waves, the sounds perceived by the ear differ in three ways: (1) They differ in pitch. If the sound-waves are long and the number of vibrations few per second, the pitch is said to be low and the sound is called grave; as the number of vibrations increases, the pitch is said to rise and the sound to be higher; if the number of vibrations is very great and the length of the waves correspondingly small, the sound becomes shrill and piercing. It is found that the vibrations must be as numerous as 24 per second in order that the ear may be able to unite them as a continuous sound. Similarly, if the vibrations exceed 30,000 to 40,000 per second, they Sooner shall gra in Hyde-park Circus grow, And wits take lodgings in the sound of Bow. Pope , R. of the L., iv. 118. 5.

Noise is that effect upon the ears which does not convey, and is not meant to convey, any meaning: as, the noise made by a falling chimney; street noises. Sound is a general word, covering noise and intelligible impre ions upon the auditory nerves: as, the sound of cannon, of hoofs, of a trumpet, of prayer. Tone is sound regarded as having a definite place on the musical scale, or as modified by feeling or physical affections, or as being the distinctive quality of sound po e ed by a person or thing permanently or temporarily: as, his tones were those of anger; a piano of peculiarly rich tone.
