What is the physical action which produced sound?

Answer 1

Sound is a form of Energy that creates a sensation of hearing in our ears . Sound is produced by Vibration that is contraction and expansion of the Sound Particles . We can see this at our home speakers the Vibration . Sound in physics is produced by vibrations which carry energy across a medium such as the air.

As you talk, the air in your mouth is pushed and vibrates air molecules in front of the air molecules in your mouth to transfer the energy/sound waves. This keeps happening until the sound reaches, say, another person.

Inherently, the sound as you go farther away decreases because you lose energy because the world is not ideal in a physics-sense.

Sound differs based on amplitude and frequency.

High frequency corresponds to high pitch as does low frequency to low pitch.

High amplitude corresponds to loud sound as does low amplitude to low sound.

Answer 2

Sound is produced by a rapid compression and rarefaction of a physical medium generally air(any physical medium can carry sound waves, sound cannot pass through a vacuum). The "pitch" of the sound is simply the frequency of these compressions. So the more frequent the compressions(i.e. the more compressions per second) the higher the "pitch". Your ear feels these compressions and rarefactions and turns them into an electrical signal that is interpreted by the brain as a pitch. The intensity of the compressions determine the volume of the sound, or how loud it is.

Answer 3

Sound is produced by the vibration of an object, such as vocal cords vibrating when speaking or an instrument string vibrating when plucked. These vibrations travel through a medium, like air or water, causing changes in pressure that our ears can detect as sound.
