Prediction, measurement and assessment of industrial noise and vibration

Industrial noise and vibration has accounted for a large part of the work undertaken by ISVR Consulting for four decades. We have experience over a very wide range of industries, large and small, including:

Assessments of industrial noise are necessary:

Prediction, Measurement and Assessment

Frequently the prediction, measurement and assessment need to be combined within a project. New developments or the expansion of facilities require design studies of noise and, less frequently, vibration to be undertaken so that statutory or planning noise limits can be met. ISVR Consulting applies both empirical and theoretical prediction methods from the first stages of a project, in order to:

Prediction

Computer-based noise prediction methods used by ISVR Consulting include:

Additional, state-of-the-art knowledge gained from many, wide-ranging research projects is available within our parent department, the Institute of Sound and Vibration Research.

Measurement

ISVR's facilities include anechoic and reverberant test chambers for measuring the noise of equipment to British and International standards. When industrial equipment has to be run in-situ,  ISVR Consulting can offer measurements of sound pressure level, sound power or sound intensity on site. Similarly, vibration and strain can be measured either in the laboratory, or if necessary, on-site:

Measurements on site are carried out using ISVR Consulting's own portable battery-powered instrumentation which is adequate for most needs, and is regularly serviced and calibrated in-house,

Additional instrumentation can be obtained if necessary for high channel counts or to meet intrinsic safety requirements.

Analysis of noise or vibration signals is undertaken using specialist frequency analysers, supplemented where appropriate by computer acquisition and digital processing.

ISVR is developing methods for the measurement of unsilenced gas turbine noise on site to enable the optimisation of noise control treatments.

Assessment

ISVR has been involved in the development of many noise standards, criteria and codes of practice. This experience ensures a good understanding of such specifications, criteria and limits, and helps us to provide:
