What is RT60 and what is it used for?
Sound is made by pressure waves. Those waves spread from their starting point and bounce around walls, ceilings, floors and every surface, losing energy over time.

What is comb filtering?
The filtering function that arises when a signal is added to itself after having delayed in time is called a comb filter. The resulting frequency response resembles a comb, hence the name.

How do standing waves influence sound fields?
Parallel walls in the room should be prevented. Then the strongest modes are suppressed. When placing the monitors it is important that as few modes as possible are excited. This is why the monitors should not be placed in a maximum of a standing wave. At low frequencies a monitor can be considered as to radiate the sound energy in all directions.

What are room modes?
The special frequencies are also called room modes. Standing waves between parallel walls are called axial modes. Other modes exit. For instance tangential and radical modes. (See the illustration). Normally the axial modes are the strongest.

What is the Sabine formula?
Wallace Clement Sabine is the father of modem acoustics. He found that reverberation time is described by a relationship between the room size and the amount of absorption in the room. Larger rooms – longer reverberation. More absorption – shorter reverberation.

What are reverberation times?
The reverberation time measurement is defined by the time it takes a sound to attenuate 60 dB after the source is stopped. In the real life we can experience reverb times from approximately 0 sec. (outdoors or in anechoic chambers) to something like 10 – 12 sec. In special reverb chambers the time may exceed 20 sec. Control rooms normally should have a reverb time around 0.2 – 0.3 sec.
