The theory of sound being produced in waves was introduced in the first century, A.D, by Seneca, the Roman philosopher. There are actually several well-known Italians who dabbled in the science of sound and its properties, of which sound reflection would be one. Leonardo da Vinci and Galileo, two other well established scholars, also experimented with sound waves and their properties. The establishment of just who was first to discover the theory of sound reflection is a little enigmatic, outside of that.

Sound propagates itself in longitudinal waves, which have compressed areas and longitudinal areas. Sound, since it travels as a longitudinal wave, requires a medium through which to travel, such as air. Sound waves can strike a hard reflective surface and reflect, or rebound, in an angle which is complementary to the angle of incidence. We call this reflected sound an echo. Areas that have hard, polished surfaces produce the best sound reflection, while areas that have softer surfaces tend to absorb sound waves.
