Oct 17, 2024 · Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective, but unduly restrictive, definition of sound is also possible, as that which is perceived by the ear. Learn more about the properties and types of sound in this article.
SOUND meaning: 1 : something that is heard; 2 : the speech, music, etc., that is heard as part of a broadcast, film, or recording
sound, Mechanical disturbance that propagates as a longitudinal wave through a solid, liquid, or gas. A sound wave is generated by a vibrating object. The vibrations cause alternating compressions (regions of crowding) and rarefactions (regions of scarcity) in the particles of the medium.
acoustics, the science concerned with the production, control, transmission, reception, and effects of sound. The term is derived from the Greek akoustos, meaning “heard.”
There is an age-old question concerning the definition of sound. If a tree falls in a forest far from any sound detector (such as a human ear or a microphone), does the tree’s crash make any noise? The answer, of course, depends on how sound is defined.
Sep 21, 2024 · Ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term sonic is applied to ultrasound waves of very high amplitudes. Hypersound, sometimes called praetersound or microsound, is sound waves of frequencies
Oct 4, 2024 · Sound waves are vibrations of air molecules carried from a noise source to the ear. Sound is typically described in terms of the loudness and the pitch of the wave. Loudness (also called sound pressure level, or SPL) is measured in logarithmic units called decibels (dB).
Sound intensity, amount of energy flowing per unit time through a unit area that is perpendicular to the direction in which the sound waves are travelling. Sound intensity may be measured in units of energy or work—e.g., microjoules (10-6 joule) per second per square centimetre—or in units of
Oct 11, 2024 · Diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wavelike properties.
A sound is anything that can be heard. Music, the barking of a dog, the wailing of a siren, and the voice of a friend are all sounds. What Makes Sound For a sound to be made…
