The establishment of quality standards by subjective assessment
B.B.C. methods for subjective testing in the field of electro-acoustics are described. The B.B.C. endeavours to reproduce the original sound because only in this way is a reliable standard available. From considerable experience it has been found to be quite impossible to make reliable
comparisons subjectively unless the acoustics of the originating studio are good. Loudspeaker testing is used as an example, although the methods are applicable to other types of electro-acoustic equipment.
