Abstract
AT the November meeting of the British Institution of Radio Engineers, held at the lecture hall of the Institution of Structural Engineers on November 21, Dr. L. E. C. Hughes read a paper on “The Technical Basis of Sound Reproduction”. His treatment of the subject was based on his experiences as technical adviser to the Central Council for School Broadcasting, and was general in character. Dr. Hughes described the various degrading effects on sounds by the chamber in which they are emitted or reproduced. The final test is always a subjective one, and owing to the short memory of the ear it is necessary for comparisons between the original performance and the reproduction to be direct. This is difficult, and the method Dr. Hughes advocated was to use two separate chambers with a microphone in each to represent the listener, and to compare their outputs subjectively at the remote end of a very good quality amplifier.
