Frequency weightings based on subjectively dominant spectral ranges

Abstract

The optimisation of frequency weightings for the assessment of environmental and transportation
noise has been an enduring research theme, with no real consensus achieved, other than increasing
acknowledgement that the widespread adoption of the A-frequency weighting is an essentially
arbitrary choice. Based on the results of 4 illustrative case studies, we propose a simple
hypothesis that the 'best' frequency weighting in any specific context depends on which part of the
frequency spectrum is subjectively dominant. This hypothesis helps to explain why different
frequency weighting schemes appear to work 'best' in different situations and allows the selection
of frequency weightings for use in assessment procedures to be carried out on a more rational and
possibly less partisan basis. Further work is of course necessary to develop and extend our
hypothesis to a wider range of different circumstances.
