Noise measurement and calculation

BS 4142, BS 8223 and the World Health Guidelines all give values and design ranges for the measurement of noise. All of this guidance involves limitations on what circumstances are appropriate for their use. It is very unlikely that anyone other than a qualified, experienced noise consultant will be able to carry out an assessment of the noise. A representative assessment will be required; this will take into account the information provided by the documents above, in addition any special circumstances must be mentioned in any report. e.g. tonal values, impact noise, number and loudness of individual events, weather conditions etc. Shortened measurement periods may be acceptable provided they are agreed in advance.

The noise assessment needs to cover the noisiest periods, taking into account the character of the area. It is also important to study the night time noise levels. Account should be taken of shift patterns in commerce and industry and any entertainment noise and vibration.

Specific information individual to each site must be recorded, In particular where there are isolated events which would not be represented in an equivalent noise level [LAeq] taken over a longer period. e.g. a freight train which passed at 5:00am each morning, or unpredictable impact noise. Potentially high incident noise levels for short time periods may cause sleep disturbance.

Information required:

Upon obtaining the appropriate external noise level data for a particular site and taking into account the internal noise standards set out below a suitable noise insulation scheme should be stated.
