The dBadge2 Noise Dosimeter mounts on the worker's shoulder and measures the noise exposure throughout the day or working shift. The dosimeter is powered by a rechargeable battery, giving up to 35 hours between charges. The built-in microphone is protected by a windshield. All measurements are stored to the internal memory for download to a computer or to be transferred to a mobile phone or tablet via Bluetooth.
Designed for the industrial environment, the dosimeter case is made from impact resistant and absorbing plastics.
The microphone is protected by the integrated windshield.
The color display clearly shows the state (running, paused, etc) of the dBadge 2. Despite the small size of the dosimeter the display is very easy to read.
The dBadge2 mounts on the worker's clothing, attached with simple but strong clips.
The clips are connected to the dBadge body by short, flexible straps, so they do not restrict the worker's movement.
The docking station and charger connects to the computer's USB port for download.
Once connected, the dBadge2 in the left-hand docking port is available for download.
The free Airwave application connects to the dBadge2 wirelessly using Bluetooth.
The Airwave app controls multiple dBadges without disturbing the workers.
As you are not with the noise dosimeter during the measurement process, you need ways of knowing whether the process was interfered with. Typical problems are:
The keypad and display can be locked to prevent it from being switched off or its settings changed. With the display off the urge to make noise to see the numbers change is removed!
To ensure that the dBadge2 hasn't been taken off in an attempt to influence the results, it presents you with a motion index expressed as a percentage the time.
The Time History Noise Profile (graph of sound level over time) is also useful. You can usually tell at a glance whether the noise levels through the day were as expected. The Time History includes a number of noise parameters (LAeq, LCpeak, LCeq, etc) along with a motion indicator.
Occupational noise regulations around the world specify the standards that noise monitoring equipment should meet. It is essential that your sound level meter or noise dosimeter meets these standards.
The dBadge2 is designed to meet all the international regulations. For the most common regulations, such as those used in the North America and the EU, it has pre-programmed settings. To satisfy any other regulations parameters such as the Exchange Rate (3 or 5 dB), Threshold and Criterion Level can be changed. See the Specifications page for more details of the settings available.
The dBadge2 effectively has three meters built in. This is very useful for certain USA regulations such as OSHA, were you need to measure with different Threshold settings to make the Personal Exposure Limit (PEL) and Hearing Conservation (HC) measurements. Or you can measure to ISO and OSHA at the same time.
The dBadge noise dosimeter continuously measures the sound levels throughout the working day and calculates the worker's noise exposure.
Other Parameters - Useful for additional assessment or used by other regulations
For a full list of parameters measured please visit the Specifications page.
The dBadge2 also stores the Sound Level, Leq, Peak and Max values every second along with the motion index. Although not needed by the regulations, we consider this essential to allow you to check the noisy times of the day and also to check against tampering.
Kits contain dBadge2 Dosimeters, Calibrator, Dock/Charger, Peli Case and Software.
Kits with 1, 2, 3 and 5 dBadges have one 3-way charger. Kits with 10 dBadges have two 3-way chargers.
