It is very common to arrange for comparisons of PA systems. However, often these comparisons are organized in a way, leaving procedures less transparent and results rather unclear. Standards for the assessment of loudspeakers do exist. The assessors basically must be trained for the purpose, and the set-up should support double-blind testing. However, in the test of large systems, the listening panel is not necessarily trained, and the practical problems of rigging huge arrays to some degree may weaken the procedures and the results. Also, finding a common denominator for the adjustment of several, sometimes very different systems, can be a problem.
This workshop seeks to provide good advice from experts in the field. Further, it reports the experience from double-blind testing that solved many of the problems in connection with a session testing five line arrays.
