Abstract
This paper describes the investigation of a simplified field method of measuring the aggregate adverse deviation of a partition. In this study, the source spectrum in the source room was assumed to be flat over the sixteen one-third octave frequency bands of 100 Hz to 3150 Hz. Measurement of the overall level difference in dB(A) is proposed. Using real transmission loss data, it was found that there was a linear relationship between the aggregate adverse deviation and the level difference in dB(A). The correlation is very good. The investigations show that a simplified method can be developed to rate partitions according to the criterion specified in the British building regulations. The simplified field method can also be applied to situations which use a different grading curve such as the grading curve for flats in Scotland. © 1983.
