Measuring Noise Exposure
Using the dBadge Noise Dosimeter
All versions of the dBadge Noise Dosimeter - Lite, Standard and Plus along with the Intrinsically Safe version - operate in the same way. The only difference is in the measurements that are available for download.
1. Charge the dBadge
The dBadge has batteries that will operate for up to 28 hours between charges. The dBadge takes just 90 minutes to charge from flat.
To charge the dBadge simply slot it onto the the charging block.
2. Calibrate
To calibrate the dBadge, remove the windshield and fit the dosimeter's microphone into the Calibrator cavity. When the Calibrator is switched on the dBadge will automatically switch into Calibration Mode.
3. Mount the dBadge on the Worker
The dBadge is supplied with two mounts as standard:
Crocodile Clip - The easiest and quickest to use. Particularly suited to thinner material.
Pin Mount - A more secure mount and suited to the thicker material used in heavy duty overalls.
The dBadge should be mounted on the worker before the measurement process is started to avoid false noise events.
4. Start the Measurement
The dBadge has just two buttons, one on either side. To start the measurement, press and hold both buttons for three seconds.
Locking the Keys
To stop anybody from accidentally stopping the measurement or even purposefully tampering, the keys can be locked. This also removes the sound level from the display as this can tempt people to shout or whistle at the microphone to see the effect.
5. Stop the Measurement
The dBadge should be left to measure for the full working shift so that you get the full noise exposure. You can measure for a shorted period and then calculate the exposure, but far better to measure it instead.
Stopping the dBadge is similar to starting it. Simply press the two buttons and hold for three seconds. Of course you have to unlock the keypad first if you chose to lock it.
6. Viewing the Results
The main noise parameters (LAvg, TWA, Leq, LEPd, etc.) can now be viewed on the dBadge's display. It simply cycles through the values on the display. All you need to record is the LAvg, TWA, Leq, LEPd (depending on regulations), duration and Peak. If you want more than this then it is better to download to the Insight software.
7. Downloading
The dBadge connects to a computer using the Infra-Red adapter that is included. This cable connects into the computer's USB port. When the dBadge is placed near the cable it is detected and the measurements are automatically downloaded to the Insight software.
The downloaded measurements can be allocated to a person, place or process for reporting purposes.
