In the most general sense, sound is the propagation of density waves through some medium. The medium most commonly encountered by most human beings is air, but sound also travels through water, rubber, steel, and tofu. In fact, most homogeneous substances conduct sound.
22 Απρ 2020 · The paper describes in a popular form about what sound is. There are two global contradictions in the idea of sound as mechanical waves. The first contradictions - is the Fletcher-Munson...
What is sound? It’s the wave that is created by vibrating objects and propagated through an elastic medium from one location to another. Air is an example of elastic medium. Elasticity of the medium increased as the distant between the molecules decreased.
Sound is the phenomenon we experience when our ears are excited by vibrations in the gas that surrounds us. As an object vibrates, it sets the surrounding air in motion, sending alternating waves of compression and rarefaction radiating outward from the object.
The spectrum of light is the primary link between optics and atomic physics and other sciences such as astrophysics. The basis for almost all instruments for spectral analysis is, again, interference.
The physical phenomenon of sound is a disturbance of matter that is transmitted from its source outward. Hearing is the perception of sound, just as seeing is the perception of visible light. On the atomic scale, sound is a disturbance of atoms that is far more ordered than their thermal motions.
To the physicist, sound is a pressure wave that propagates through an elastic medium (i.e., the air). Molecules of air are alternately bunched together and then spread apart in a rapid oscillation that ultimately bumps up against the eardrum. When the eardrum wiggles, signals are sent to the brain, causing "sound" in the psychologist's sense.
