Sound is created by vibrating things. Sound has three properties.
One property is that sound can travel in all directions. This is proven by standing 1 meter away from the source in all directions and making a sound.
The second property is that sound can travel around corners. This is proven by standing behind a wall and making a sound.
The third property is that sound dissipates as it travels. This is proven by standing far away from the recorder and comparing the level of sound from a near meter and a far meter.
