Railway noise and vibration
The central reference document in the UK for the monitoring and prediction of railway noise is the technical memorandum 'Calculation of Railway Noise' (CRN). This document was published by the Department of Transport in 1995 to provide a standardised approach to noise assessments undertaken in connection with the Noise Insulation (Railways and Other Guided Transport Systems) Regulations 1996. These Regulations were themselves introduced to provide means of delivering compensation to property owners whose properties were adversely affected (at or beyond the criteria specified in the Regulations) by noise from new or altered railways.
CRN provides information on the monitoring of railway noise and its prediction from traffic flow counts or forecasts, taking account of factors such as vehicle type and speed.
It also includes a comprehensive series of noise prediction techniques which take account of the sound attentuation which can derive from propagation distance, reduced angles of view of the noise source, acoustic barriers and soft ground absorption.
Auracle Acoustics is able to undertake all aspects of the monitoring, prediction and assessment of railway noise and vibration in accordance with national guidance such as CRN, PPG24, BS6472 and the specific requirements of local planning authorities, including the preparation of acoustic reports to support planning applications and liaison as required.
Information on the various means of controlling and mitigating against noise from sources such as railways may be found on the Noise Control page.
