USING THE CORRECT NOISE MONITORING EQUIPMENT

Noise exposure can be prevented, but its effects can be permanent and debilitating. Noise is a common occurrence in the workplace, especially when workers use high-powered equipment and tools. Long-term exposure to high levels of noise can be dangerous and prevent workers from performing at their best. Monitoring can be used to improve such conditions by providing concrete data, highlighting areas for improvement, and highlighting ways for change. However, it's essential to understand the distinction between a noise meter and a dosimeter when considering noise monitoring equipment hire. Monitoring provides accurate information about noise levels. However, with so many products on the market, it is difficult to determine which product will be most appropriate for your workplace.

Sound level meters

The sound level meter, a portable device, allows measurements to be taken in the ear (within a range of 10 cm to 15cm) while pointing the instrument at the source of noise. The process must be repeated on both ears, for each duty performed by the employee. This allows for an accurate recording of exposure. These meters have adjustable settings that can be adapted to the noise type being measured. Monitors must be compliant with the IEC 61672 class 2 international standard to ensure accurate measurements.

If you are using a sound levelmeter, it is important to start the measurement at the beginning of each task. This will represent workers' exposure. For accurate results, it is important to measure peak noises and compare them with the peak levels that are likely to be experienced by workers exposed to high levels impulsive noises, such as those emitted during heavy pressing operations or sheet-metal working. Sound level meters are preferred for noise surveys because the operator can ensure the quality of the measured noises. The exposure time is calculated for each job function and a representative measurement made.

Dosimeters

Dosimeters measure the personal exposure. They are small devices that can be worn on the shoulder. The devices can be set up at the start of a shift, and used until the end. Data can then be downloaded onto a computer to show the history of noise exposure, and highlight areas of high exposure. The employer can see which operations require better noise control if the dosimeters are placed on employees who keep a daily diary.

Dosimeters are best used for people with complex work patterns and varied noise exposure or for certain tasks such as driving a forklift truck, which can be difficult to monitor using a sound levelmeter. Remember that employees can give false results when using noise dosimeters, especially at first. It is important to check high exposures and determine if they are part of a worker's legitimate exposure. Modern noise dosimeters are able to record audio. The sound can be played back in order to determine the source of the noise, for example, if it is a machine or if the exposure is false.

To ensure compliance, employers should purchase dosimeters compliant with IEC 61252 standards.

Monitoring

Sound level meters are easy to use, quick and simple. They can be used to collect accurate information about workplace noise exposure for any job.

Employers can change their workplace practices by investing in monitoring systems. They could also implement noise control to prevent employees from suffering hearing problems and long-term effects as a result.
