Designed to accompany the new Open University course in Environmental Monitoring and Protection, this is one of four new titles which will equip the reader with the tools to undertake Environmental Impact Assessments (EIAs). Used in planning, decision-making and management, EIAs review both the theoretical principles and environmental considerations of engineering and environmental projects to help steer fundamental legislation in the right direction. This book will cover the basic principles and concepts of sound and sound propagation, covering units, criteria and indices. It considers noise propagation and attenuation, before leading on to assessment methods for both industrial and transport noise. It includes models for predicting sound levels both indoors and outdoors, and details methods for noise control and abatement.
