Science behind the sounds

How Sound Travels in a Room? 

Whenever a sound is made in a room, starting at the source, it projects outward in all directions. A small portion of it (known as direct sound) travels in a straight line to the microphone. The remainder (known as reflected sound) bounces randomly between the surfaces of the room. Moments later, some of those reflections reach the microphone by chance. Since direct sound does not interact with the room, its frequency balance remains pure, and its tone unaltered. With reflected sound, each new reflection has the potential to change the original sound ever-so-slightly. Depending on the size of the room, and the reflective surfaces within it the change should be either large or small. 

How Diffusion Improves Your Sound?

When you remove all sound reflections with absorption many people find that the room sounds uncomfortably quiet. The solution here is allowing a few reflections to remain, and scattering them with diffusors. Normally, untreated reflections create problems because they get trapped in one spot, amplifying some frequencies, while canceling out others.This is how the natural frequency balance gets destroyed. Diffusors work by scattering reflections so nothing gets trapped, and the natural tone is preserved.With the right combination of both absorption and diffusion, you can transform the acoustics of virtually any room into something capable of a world-class recording.
