Sound is usually an acoustical wave in air. When this is converted e.g. by a microphone to an electrical voltage that can be sent through a wire. An amplifier and a loudspeaker can convert this audio signal back to an acoustical wave, you can listen to.

Does sound travel up or down in a vacuum?

Sound does not travel in a vacuum because it requires a medium, such as air or water, to propagate. In the absence of a medium, there is no material for sound waves to travel through, so sound cannot travel up or down in a vacuum.


How fast can sound waves travel in copper wire?

Sound waves can travel at a speed of around 4,920 meters per second in copper wire. This speed is dependent on the material properties of copper, such as its density and elasticity.


Can sound travel through copper or metallic wires?

Best way is to first turn sound in to electrical energy and transmit. (Using a transducer-- device that receives a signal in the form of one type of energy and converts it to a signal in another form: A microphone is a transducer that converts acoustic energy into electrical impulses.)Sounds waves can be placed on the wire directly. String a wire tightly between two poles. Strike one end (or pluck it) and the sound will travel down the wire tot he other end. Note that the signal will not travel nearly as far as an electical impule due to the amount of energy necesssary to move the wire.


Does sound travel up or down within an apartment?

Sound travels in all directions within an apartment, including up and down.


Does noise travel up or down in a vacuum?

In a vacuum, noise does not travel because there are no particles for the sound waves to travel through.


Does sound travel faster through space or room temperature?

Sound can travel faster through space because space is a vacuum where there are no particles to slow down the transmission of sound waves. In a room at room temperature, sound travels through the molecules of the medium, such as air, which can slow down its speed.


Who developed a machine that allowed sound waves to travel across a wire as an electrical current?

Alexander Grahm Bell


What would happen if a wire in a parallel circuit broke?

All of the current would travel down the remaining intact wire - possibly overheating.


Why is there sound when wind blows past a telephone wire?

The wind pushing past the wire creates a low pressure zone on the downwind side of the wire. As air rushes into this low pressure zone, collisions between pressure fronts creates vibrations in the air, perceived as sound.


How does sound travel through wire?

Sound travels through wires in the form of electrical signals, which are converted from sound waves by a microphone. These electrical signals then pass through the wire to a speaker, which converts them back into sound waves that we can hear. The wire acts as a conductor for the electrical signals, allowing the sound to be transmitted efficiently across a distance.
