The Guidelines are applicable to noise impact assessment for any scale of development proposal, including core principles to achieve effectively integration with the Environmental Impact Assessment (EIA) process. From scoping the assessment, through establishing an effective noise baseline, to identification of noise impacts and describing their consequential effects the guide provides a comprehensive view of delivering quality practice. The Guidelines provide a valuable guide for all acoustic professionals involved in environmental noise and will provide useful reading for EIA co-ordinators, local planning officers and anyone interested in the field.
