Why is sound energy?

Question

Could someone explain the steps of how sound is made? Does vibration cause energy, or does energy create the vibration?

Thanks!

Answer 1

They're one and the same: Energy sources cause vibration--which is a direct result of harmonic energy, that has infinite wavelength bands. We currently know of such wave bands we can evidently hear (and in some cases, feel) and there are those wavelengths that cannot be heard by our ears--or even felt by our senses.

Answer 2

In general waves can be propagated, or transmitted, transversely or longitudinally. In both cases, only the energy of wave motion is propagated through the medium; no portion of the medium itself actually moves very far. In transverse waves, the material through which the wave is transmitted vibrates perpendicular to the wave’s forward movement. As a simple example, a rope may be tied securely to a post at one end, and the other end pulled almost taut and then shaken once. A wave will travel down the rope to the post, and at that point it will be reflected and returned to the hand. No part of the rope actually moves longitudinally toward the post, but each successive portion of the rope moves transversely. This type of wave motion is called a transverse wave. Similarly, if a rock is thrown into a pool of water, a series of transverse waves moves out from the point of impact. A cork floating near the point of impact will bob up and down, that is, move transversely with respect to the direction of wave motion, but will show little if any outward, or longitudinal, motion.
To record sound, a microphone changes the acoustic energy of sound waves in the air into electrical signals. Inside a microphone is a thin, flat, metallic surface, called a diaphragm, that is suspended in a magnetic field. When a sound wave reaches the microphone, the air pressure changes around the diaphragm, causing the diaphragm to move. This movement within a magnetic field creates an electrical signal. The signal is then transferred to a storage medium, such as a cassette tape, a compact disc (CD), or a phonograph record.

Answer 3

Energy exists in more than one form.
We have heat energy, sound energy, light energy, electrical and potential and Kinetic and atomic etc......
Energy is transferable and so vibration can cause sound to be produce and sound too can make things vibrate,

Answer 4

Is sound energy?

Energy creates motion that creates air vibration.

Answer 5

me thinks vibrations cause energy and vise-versa.
