A construction project includes multiple types of machinery, and they generate a lot of heavy machinery noise, causing a disturbance. Earthmoving machinery, heavy vehicles, compressors, pile drivers etc., contribute to increasing Db(A) emissions. With such heavy machinery, managing noise control can become extremely challenging.

As per the National Code of Practice, the noise exposure must not be more than 85dB for 8+ hours every day or shift. Along with these, engineers can’t be exposed to peak noise as well that goes beyond 140dB. And this is the reason why construction companies use a remote noise monitoring system to monitor the level of noise.

Noise Dosimeters

If someone gets exposed to noise that is 140dB and above, it will cause pain to their ears and, worse, can-do damage to ears. Noise dosimeter calibration thus becomes helpful. Noise monitoring devices, such as noise dosimeters, contain data loggers. This device helps in capturing the noise exposure period. The software used allows the device to manipulate the data in such a way that the engineer can present it in a presentable format. 

One can buy noise dosimeters for sale and do a field check with the calibrator before using it, and even after using it should be checked to determine whether the noise monitoring system is working correctly or not. In addition, the remote noise monitoring system should be carefully placed, ensuring that the device’s microphone is as close to the ear. 

Sound Level Meters

Sound Level Meters, otherwise known as SLM, is another beneficial device that engineers can use for a construction project. SLM is an essential tool that will let you figure out the overall noise level of an area, piece of machinery, and task. 

You will find a good sound level meter calibration to stipulate the noise level of a work that is compliant to work assessments. It should be at least a Class 2 sound level meter calibrator. With the help of this device, the engineer can figure out LCPeak and LAeq exposure and more.

Benefits of Using Noise Dosimeters and Sound Level Meters

  • With increasing noise pollution at construction sites, engineers are constantly exposed to varying noise. With the help of noise dosimeters and sound level meters, one can have important information, such as the intensity of sound waves. 
  • Such devices can help you stay compliant with noise regulations, prevent hearing loss, control noise, and avoid residents and community annoyance. For example, in Australia, loss impacts almost 28-32% of construction workers, and that’s why there is a massive requirement for noise dosimeters and sound level meters. 
  • Sound Level Meters should be used to measure the noise level of the project that is being handled and find out how noisy the particular location and machinery are. 
  • Noise dosimeters turn out to be helpful when you want to find out the direct noise exposure. Based on the reports provided, employers can then decide about the various noise protection gears that should be provided to the employees. 
  • Both the devices can provide users with consistent and accurate results, which will help the employers understand what steps they should take to control the noise pollution caused by the construction work and keep their engineers safe from such hazards.
