Relaxed room-standard requirements eroded the comparability that motivated them

Evidence

The original document envisaged the construction of “standard” listening rooms that would allow for comparisons of experimental results obtained within them. Only a few such rooms were built; expense was a factor. Later editions of the document relaxed the requirements to the point where many rooms would qualify as meeting the requirements, eroding the key point of the recommendation but pleasing those wishing to be able to justify use of their existing rooms (IEC 60268-13 1998). — Toole, Floyd E, Sound reproduction- the acoustics and…, 145
