Pulsar noise testing equipment for construction industry - Construction & Construction Materials
The construction sector and its wide range of associated activities are very varied and from a noise monitoring perspective offer many unique challenges. However, Pulsar Instruments have a solution; a construction Pulsar noise meter with the ability to effectively assess the following two key categories; Noise at Work (potential for noise induced hearing loss due to long term exposure to noisy activities). Environmental Noise (the potential to cause annoyance to surrounding areas or buildings during site work).
Both of these key areas can be assessed by Pulsar Instruments fully compliant, accurate, easy to use, and most importantly, robust sound measurement and monitoring equipment to help you address these particular noise issues effectively.
The Construction Industry is different from, for example factory and manufacturing because work patterns vary considerably and projects can last from a few days to a few years.
Often on site you need to take quick decisions and understand if there are likely to be any noise issues. By using a simple ‘decibel meter’ such as the Model 14 you have a cost effective, ideal, compact and ‘easy to use’ instrument that can be transported from site to site allowing you to make a quick judgement regarding noise levels.
This is particularly useful where a more expensive instrument would be cumbersome and more prone to the risk of on-site damage or misuse. The Model 14, low cost noise meter, is supplied with a wind-shield as standard to protect the microphone capsule and has two selectable ranges to allow you to quickly gauge both environmental and industrial level noises.
The instrument is fully compliant with IEC 61672 and can be supplied with an acoustic calibrator if you wish to verify your measurements.
The robust, simple to use and ‘no nonsense’ approach provided by the Assessor range, Industrial Sound Level Meters, allows even inexperienced users to quickly take sensible measurements that allow you to ensure that your workforce is protected from from the effects of excessive noise exposure. For example the Model 82CAK Assessor noise measurement kit provides you with all the tools required to carry out your noise risk assessments and also cost effectively and accurately determine suitable hearing protection with its special ‘C minus A’ measurement mode.
You can quickly refer to the HML values provided by the hearing protection manufactures for specific muffs, inserts etc and by using a simple spreadsheet (HSE website link) ensure you are not over or under protecting your work people.
This is crucial on a busy site as ‘over protection’ can isolate workers who may not be able to hear alarms or communicate effectively. Being badly injured by moving plant or objects because you can’t hear what is happening (or warnings from colleagues) is something that can easily be avoided. Monitoring their noise levels giving an overall exposure at the end of each working day. The doseBadge system is also very useful in almost all Noise at Work applications, especially as it is so small that it does not change the work patterns.
Noise assessments or noise monitoring can be undertaken at many levels from a simple ‘spot check’ measurement (to determine if there is the likelihood of a problem) to a continuous monitoring system (to ensure continued compliance with local authority recommendations). An excellent instrument for both Industrial noise and environmental noise applications is the Pulsar Model 30 Real Time Analyser, which is used on many UK construction sites.
It is often useful to determine that potentially noisy activities are not likely to reach excessive levels at sensitive boundary positions (usually nearby local domestic housing or offices). The Model 14 would be a low cost solution for this type of measurement. The powerful Class 1 Model 30 instrument allows you to compare average noise levels at boundary positions against the L90 (typical background noise levels).
Single or repeated ‘fixed duration’ measurements
Often a hand held instrument such as the Model 30 would be mounted on a tripod at a boundary position and, for example, a 15 minute measurement made. Often it is necessary to make a continuous series of similar ‘fixed duration’ measurements and store these into the instruments memory for which the Model 30 or Model 33 are ideal.
For certain applications specific noise sources such as extraction fans and wind turbines cause annoyance at specific frequencies. It is often a requirement to monitor real time 1:3 Octave Band noise levels to determine when these events are occurring and the likelihood of annoyance.
There are many engineering solutions available to reduce noise levels and by performing a 1:3 Octave Band Analysis before and after this work you can determine and report the effectiveness of such improvements.
