NR Special Projects team, have the background knowledge to offer a full range of noise surveys for any environmental noise application. Our surveys conform to all the latest British Standard Regulations.
Environmental noise surveys are required in numerous commercial and industrial projects within the private and public sector and are carried out in accordance with detailed methodology which has been outlined below:
BS4142:1997 - Method for rating industrial noise affecting mixed residential and industrial areas
DESCRIPTION: Methods for determining the level of industrial noise affecting mixed residential and industrial areas.
BS 7445-1:2003 Description and measurement of environmental noise. Guide to quantities and procedures.
DESCRIPTION: Guidance on quantities and procedures for description and measurement of noise in community environments.
BS 8233:1999 Sound insulation and noise reduction for buildings. Code of practice
DESCRIPTION: This British Standard gives recommendations for the control of noise in and around buildings, and suggests appropriate criteria and limits for different situations. These criteria and limits are primarily intended to guide the design of new or refurbished buildings undergoing a change of use, rather than to assess the effect of changes in the external noise level. This standard covers room acoustics for simple situations, but not the design of buildings where the acoustics are critical, such as auditoria.
BS 4196-2:1991, EN 23742:1991,ISO 3742:1988 Sound power levels of noise sources. Precision methods for determination of sound power levels for discrete-frequency and narrow-band sources in reverberation rooms.
DESCRIPTION: Acoustic measurement, Sound sources, Acoustic testing, Audio frequencies, Mathematical calculations, Precision, Sound Intensity, Reverberation Rooms, Acoustic Testing Rooms, Noise control (acoustic). Testing conditions, Noise (environmental).
