✦ Synopsis

In a bid to assist with the prediction of noise levels in communities where direct measurements are not possible, CONCAWE--The Oil Companies' International Study Group for Conservation of Clean Air and Water--has recently published the results of a research study designed to produce a new and comprehensive model for the assessment of noise propagation.

The work itself was carried out by Acoustic Technology Ltd of Southampton, Great Britain, in accordance with a programme defined by CONCAWE.

Entitled 'The Propagation of Noise from Petroleum and Petrochemical complexes to Neighbouring Communities', the new C ONCAWE report (No. 4181) describes in detail--with relevant supporting data--the development of an initial model, the experimental measurements, and consequent refinement of the model to produce the final and three simplified versions.

The establishment, during the study, of separate attenuation curves for six categories of weather conditions, for each of the usual octave bands, and the estimation of confidence intervals for the predictions through the application of statistical analysis, are also described in the new CONCAWE report.

A comparison between the new CONCAWE model and two other noise propagation models already in general use, as well as Tables of atmospheric absorption values, graphs and equations for calculating the attenuation parameters, and a brief description of the statistical methods used are also included.
