sound wave, and a longitudinal
The voice is not a sine wave.
numba nine (raspy voice)
A carrier wave is needed to transmit the human voice because it provides a medium for transporting the voice signal. By modulating the voice signal onto the carrier wave, the voice signal can be efficiently transmitted over long distances through the air or through cables. The carrier wave acts as a stable platform on which the voice signal can be superimposed without being distorted.
It is a type of mechanical wave known as a seismic wave.
a seismic wave
Every type of sound wave produced is a longitudinal wave.
A mechanical wave is not an electromagnetic wave.
an example of a seismic wave would have to be when you are recording your voice, sound waves come out of your mouth and you can see the line that moves up and down to the tone of your voice like triangles without a bottom varying in size.
