BS 4142:2014 - revision of the methods for rating and assessing industrial and commercial sound

摘要

Over the years BS4142 has proven to be a very valuable assessment tool, though when the committee was deliberating the revision to the standard it was apparent that it was often misapplied and that a number of practitioners were failing to achieve reasonable standards of assessment and reporting. It is hoped that the changes to the standard will ensure: 1. greater utility of the standard 2. a clear understanding of its scope and application 3. good quality measurements and calculations that are fit for purpose 4. an overall improvement in the quality of assessment of commercial and industrial sound and the impact of that sound on residential receptors. The changes to the standard should ensure that the assessment better reflects perception and response to commercial and industrial sound and, in so doing, supports practitioners, regulators and others involved in decision making so that people are properly protected from the adverse effects of noise but without imposing unreasonable financial burdens.
