Radiation space
The radiation space is the volume into which a monitor is radiating sound. The
sound level increases when the sound radiation is limited by walls. Every halving
of the radiation space by a wall close to the monitor doubles the sound pressure
level.
A monitor with a at frequency response in free space produces up to 6 dB higher
sound level against a solid wall. In a corner (two walls) this gain can be 12 dB.
With three boundaries (corner close to ceiling) the gain can be +18 dB. This can
be particularly seen at low frequencies.
