Question

could someone please give me some background information on the properties of sound waves, and how they are effected by passing through differant materials?

Answer 1

Sound waves are Mechanical waves which needs a medium to propagate from one point to other.

Answer 2

Sound waves are consist of Compressions and rarefactions.

Answer 3

Sound propagates through compressible media such as air, water and solids as longitudinal waves and also as a transverse waves in solids

Answer 4

The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. The sound source creates vibrations in the surrounding medium. As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. At a fixed distance from the source, the pressure, velocity, and displacement of the medium vary in time. At an instant in time, the pressure, velocity, and displacement vary in space. Note that the particles of the medium do not travel with the sound wave.

Answer 5

A relationship between density and pressure. This relationship, affected by temperature, determines the speed of sound within the medium.
The propagation is also affected by the motion of the medium itself. For example, sound moving through wind. Independent of the motion of sound through the medium, if the medium is moving, the sound is further transported.
The viscosity of the medium also affects the motion of sound waves. It determines the rate at which sound is attenuated. For many media, such as air or water, attenuation due to viscosity is negligible.

Answer 6

thanks so much, you have no idea how much you've helped

Answer 7

I do still need to know one thing though, what are all the properties of a soundwave (such as wavelength, amplitude, etc.)
