The ancient Egyptian water clock was made to count the hours of the night and to count how long a person speaks in a trial.
Sound consists of energy moving the molecules of a medium (air, water, rock), with a certain strength (amplitude) and vibration time (frequency). When a person speaks, the vibration from his voice pushes against the air molecules, which push against other air molecules, producing a widening wave front of molecular motion. The modulated energy of the vibration may eventually reach another person's ear. There the repeated impacts by the molecules are translated into nerve impulses, which the brain can interpret as vocal sounds. Because sound tends to spread out in all directions, there can be barriers directly between two people and yet one's voice may still be heard by the other.
