Solving problems, not creating them.

Although the ‘Control of Noise at Work Regulations 2005’ specify three levels of noise exposure, people are rarely exposed to such steady noise levels throughout their working day.

 

Noise exposure will vary depending upon location, type of activity undertaken, type of equipment used, time spent in these situations and the effect of other nearby noise sources (e.g. other machines or equipment). These factors need to be assessed and analysed to establish the overall likely noise exposure. Only then can noise exposure be compared with the levels specified in the regulations.

 

We analyse noise exposure using a Class 1 Real Time Analyser. This measures and records multiple noise parameters every second as well as calculating cumulative exposures for the period of measurement.

 

We can measure instantaneous noise levels at various locations where a person may work, ascertain how much time is spent at each location and then calculate likely daily noise exposure together with an assessment of  how this may vary if the work pattern is changed. This approach gives a much better assessment of noise exposure than traditional dosimetry.

The  Real Time Analyser allows us to produce a graph so we can analyse the noise thoroughly.

    

The datalogging function shows how the noise varies from second by second. This allows us to see which is the noisiest part of process.

 

The software allows us to calculate the effect of removing or reducing the noise from a particular part of a process. This means that we can predict the effectiveness of any planned sound reduction measures.

The noise meter has Octave Band Analysis capability.

 

This measures the noise level at various frequencies, as shown above.

 

This type of frequency analysis is the preferred method of assessing whether the type of hearing protection that is in use is suitable for the type and intensity of noise.
