The noise dosebadge: What it is and how it can be used for occupational noise measurements

The noise dosebadge is considered to be the original wireless noise dosemeter. Like the noise level meter, a noise dosebadge is an invaluable instrument in conducting occupational noise measurements. However, noise dosebadges and noise dosimeters have one distinct advantage over noise sound level meters when used for occupational noise measurement - they take transportable noise measurements.

Changing dynamics of the workplace

The increase in completely mechanised production lines we have seen in recent decades, has led to the dynamics of the factory and other industrial or manufacturing settings, changing. Workers are no longer required to stay in the same position on a production line for the entirety of their working shift.
Today, there is much more flexibility and manoeuvrability within the workplace. As production lines become increasingly more mechanised, employees are often required to supervise or operate more than one automatic pieces of equipment. By moving from one area to another, employees are exposed to different levels of noise.

This is when the noise dosemeter can prove invaluable. Unlike the sound level meter, which is typically a hand-held device, the noise dosemeter is worn on the clothing of an employee. This small sound measuring instrument therefore travels with the employee. The microphone located in the noise dosebadge picks up the soundwaves and enables sound measurements and noise exposure to be taken throughout the whole of the working day.

The noise dosebadge is simple in its design. Despite its small size and being light in weight, the noise dosebadge is robust, providing an accurate noise measurement.

Like the noise dosemeter, the noise dosebadge is wireless, and does not comprise of any controls, cables or displays, ensuring it can be worn without getting in the way and causing a hindrance.

These dual channel devices not only measure the levels of noise in different areas, but they can store and calculate various sound measurement parameters, which can be vital in helping employers comply with occupational noise standards and regulations.

Noise dosemeter calibration

In order for noise dosemeters and noise dosebadges to maintain their accuracy, it is vital they are regularly calibrated. Occupational noise regulations stipulate that noise measuring devices, such as sound level meter, noise dosemeters and noise dosebadges, are calibrated regularly.

It is advised that these high-precision instruments are calibrated at least once a year. However, some regulations require this sound measuring equipment to be calibrated before and after every use.

Carrying out noise dosemeter calibration mean users check the general performance and condition of the noise dosemeter, noise dosebadge or sound level meter. The calibrator is placed over the device’s microphone and emits a stable and accurate tone. The user can then check the performance of the noise dose meter or other noise measurement device.

Occupational noise can be a hazard. Regular, efficient and accurate noise level measuring will help employers comply with noise at work regulations and help maintain thehealth and wellbeing of  employees.
