โฆ Synopsis
A simplifiedfield method of measuring the sound insulation of partitions within the framework of the British building regulations has been proposed and its development is described in this paper. The selection of the source type and the weighting function for the measurement of the overall sound pressure levels and the effects of loudspeaker and room response are discussed.
A simple method of normalising for receiving room absorption is proposed and evaluated. Some results of experiments, carried out both in the laboratory and in field conditions, are reported. The results of this study show that the simplified field method has considerable potential for bringing about wide-scale enforcement of the building codes, which have so far been ineffective.
