The crowded or loose grains cause the electric current to become stronger or weaker. The current copies the pattern of the sound waves and travels over a telephone wire to the receiver of another telephone. For more modern phones that have a telephone answering service, the sound wave is captured on a recording device which allows for the operator of the phone to playback at a later time.
Sound can travel through anything made of molecules-even water! There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are different from sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air and solid materials-but they can also travel through empty space. This is why astronauts on spacewalks use radios to communicate.
