CORRELATIONS BETWEEN DIFFERENT COMMUNITY NOISE MEASURES

Within the last several years there has been increased interest in the measurement of community noise, with new methods proposed for estimating community noise levels and for interpreting community noise measurements in terms of impact on people and communities. In distinct contrast to the direction of study in early post-war years, interest has shifted from detailed frequency spectral information to study of the statistical variation of noise levels with time. Thus, many recent studies rely primarily upon A-level measurements (perhaps supplemented with limited spectral analyses) but devote greater attention to the statistical properties of the noise signal. These statistical analyses are based upon studies of noise samples taken over time periods ranging from a few minutes to a number of hours. Proceeding from rather simple descriptions of the distribution of noise levels in terms of various percentiles, several more complex single number measures, such as the traffic noise index (TNI) and the noise pollution level (NPL), have been proposed and are being utilized. Most of these newer measures are derivable from knowledge of the cumulative distribution of noise levels observed over a period of time.
