One of the problems which can occur is that the diffussion desk is
(usually) placed in the 'optimum position' in the hall - optimum being
defined in terms of imaging and quality of sound rather than anything else
- the trouble is that this means that the diffusion artist may not be
fully aware of problems elsewhere in the hall, such as hotspots in the
soundfield. As a result of focussing from corners in our hall, for
instance, I have measured sound levels some 12 dB higher in certain seats
near the rear of the hall (AWAY from loudspeakers by the way) than at our
normal diffusion desk.
