The picture at the left side shows the local dependence of Sound Coloration in a non rectangular room.

'Sound Coloration' is a measure for the deviation of the Sound Pressure Level Frequency Response from an ideal linear frequency response. Distinctive peaks and dips in a frequency response indicate a high degree of 'Sound Coloration' (yellow to red colors). Dark colors (blue to black) indicate a low degree of 'Sound Coloration'.

The positions of the loudspeakers (B:1 ... B:5) are marked by blue pins. The yellow pin marks the current listening position.

From the picture you will easily notify that 'Sound Coloration' is worst in the near of the room walls. At short distances to the loudspeakers' baffles and also at the listening position 'Sound Coloration' (induced by room acoustics) is satisfying.
