When you talk into a telephone, the microphone inside of the mouthpiece transforms the sound

waves into electric impulses.

Page 8: Alexander was born March 3,1847 Edinburgh Scotland His mother Eliza Bell was born deaf. His father Alexander Melville Bell taught deaf people. His grandfather.

These sound waves are sent through the cable to the ear piece of the other

persons receiver which they are listening. This turns the impulses into sounds which

are nearly identical to the sound made by the caller, so from the impulses sent it

sounds like they are standing right next to you.
