DG Room Acoustic Treatment

Above that zone, until the frequency is approximately 11,250(RT60/V)1/2 (when Volume is measured in cubic feet and 2000(RT60/V)1/2 when Volume is measured in cubic metres),[1] wavelengths are comparable to the dimensions of the room, and so room resonances dominate. This transition frequency is popularly known as the Schroderfrequency, or the cross-over frequency and it differentiates the low frequencies which creates standing waves within small rooms from the mid and high frequencies.[2]

• The third region which extends approximately 2 octaves is a transition to the fourth zone.
• In the fourth zone, sounds behave like rays of light bouncing around the room.
