Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.
Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. (Sound can propagate through solids as well, but there are additional modes of propagation). During propagation, waves can be reflected, refracted, or attenuated by the medium.
The behavior of sound propagation is generally affected by three things:
When sound is moving through a medium that does not have constant physical properties, it may be refracted (either dispersed or focused).
The perception of sound in any organism is limited to a certain range of frequencies. For humans, hearing is normally limited to frequencies between about 20 Hz and 20,000 Hz (20 kHz), although these limits are not definite. The upper limit generally decreases with age. Other species have a different range of hearing. For example, dogs can perceive vibrations higher than 20 kHz, but are deaf to anything below 40 Hz. As a signal perceived by one of the major senses, sound is used by many species for detecting danger, navigation, predation, and communication. Earth's atmosphere, water, and virtually any physical phenomenon, such as fire, rain, wind, surf, or earthquake, produces (and is characterized by) its unique sounds. Many species, such as frogs, birds, marine and terrestrial mammals, have also developed special organs to produce sound. In some species, these produce song and speech. Furthermore, humans have developed culture and technology (such as music, telephone and radio) that allows them to generate, record, transmit, and broadcast sound. The scientific study of human sound perception is known as psychoacoustics.

Genres: Animation, Short,Take a breather, let your air out
This can get you somewhere
She's the queen of screaming shit out
If she lets you stand there
You keep ringing in my head
You always do this to me
You keep ringing in my head
Whatever happened to your song?
It's just how the radio sounds
We used to stay out all night long
Living on radio sound
You are thinking you know what's right
Nothing you can't see through
Stand and shiver, turn off your lights
And tell me no one's changed you
You keep ringing in my head
You always do this to me
You keep ringing in my head
Whatever happened to your song?
It's just how the radio sounds
We used to stay out all night long
Living on radio
You keep ringing, ringing
Ringing, ringing
Whatever happened to your song?
It's just how the radio sounds
We used to stay out all night long
Living on radio
Whatever happened to your song?
It's just how the radio sounds
We used to stay out all night long
