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.
While sound will readily travel through many materials, in order for us to hear it, it will have to travel through the air to reach our ears (eardrum). Your eardrum vibrates from sound waves to allow you to sense them. We might be able to detect it through vibration of solids, the ripple in liquid but you can only detect it in air by hearing it. In spite of this, humans cannot hear all sounds that travel through the air. It will have to be at a certain decibel for us to hear it. For e.g. dogs can hear sounds that are not able to be detected by humans. Sound can also be detected by other means other than hearing it.
