The doseBadge noise dosimeter can be rented for one week or more to assess the noise levels that your workers are being exposed to.
Particularly useful for people who move around a lot, the doseBadge kit contains five dosimeters, making it ideal for monitoring a larger number of people during the hire period.
Rental Kit Includes
Noise exposure in the workplace can be assessed using either a hand-held sound level meter or using a noise dosimeter mounted on the worker's shoulder.
With a hand-held sound level meter you measure the sound level at each location and use this with the length of time the workers spends there to calculate the exposure. With a noise dosimeter you measure for the full working shift and it provides you with the overall exposure value.
Each doseBadge (there are five in the kit) contains a rechargeable battery. The unit itself is small and light weight. It mounts on the worker's shoulder to measure the noise levels close to the ear.
The best way is to leave it measuring for the full working shift, providing you with the Time Weighted Average, TWA, and Dose % as required by the occupational noise regulations.
The doseBadge noise dosimeter is intended for measuring sound levels in a relatively noisy factory environment.
For sound level measurement in lower noise environments you should use a hand-held sound level meter. For longer term measurements these hand-held meters can be mounted on a tripod.
Suitable meters would be the Type 2 Integrating Sound Level Meter or the Type 1 Environemntal Sound Level Meter.
Leave the doseBadge measuring for the full working shift...
While it is possible to measure the Lavg over a shorter period and then calculate the TWA and Dose %, when using a dosimeter it is better to leave it measuring for the full working shift. This saves doing the potentially complex noise dose calculations and ensures you measure all relevant noise levels.
The measurements can be viewed on the Reader's built in graphic screen or they can be transferred to a computer for storage, analysis and reporting. The Reader can download a number of doseBadges before the measurements are transferred to a computer, so it is only necessary to carry the Reader on site.
