Reflections of the early reflections are called late reflections. Again, energy will be absorbed, the waves’ strength will be decreased, and further reflections will occur. These first reflections of the original signal are called early reflections.Ĭan you see where this is going? The early reflections, still in the space, will continue traveling until they too reach surfaces. Because of the energy absorption that occurred, these sound waves will be weaker (lower amplitude). This is why certain materials like foam and cork are used in studios to absorb sound.Īny energy from the initial sound wave that isn’t absorbed will be reflected, and sound waves will then travel away from the point of reflection in all directions. Generally, the surface’s material will determine the amount of absorption/reflection. These waves will continue until they reach a surface, which will both absorb and reflect the wave’s energy. When a signal is emitted (a baby crying, a car horn, a phat kick drum, etc.), sound waves will travel away from the signal source in all directions. Reverberation is nothing more than sound waves bouncing off of surfaces. Time for some quick physics! The Anatomy of Reverberation In order to best understand how we can create these environments, we should first look at what we’re trying to replicate in the first place.
