The dBadge2 PRO Noise Dosimeter mounts on the worker's shoulder and measures the noise exposure throughout the day or working shift. The noise level triggered audio recording make it possible to identify the exact cause of high noise levels. Real-time octave band filters give extra detail for analyzing tonal noise and for more detailed assessment of hearing protectors.
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 PRO mounts on the workers 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:
With this version of the dBadge you can set it to record up to 90 minutes of audio, triggered by the sound level. Using these recordings you can positively identify the cause of high noise levels.
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 noise at work regulations. For the most common regulations, such as those used in 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 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.
Audio Notes and Audio Recording are available on the PLUS and PRO versions of the dBadge2.
The dBadge2 PRO can record up to 15 seconds of voice notes at the start of the measurement. You can record the employee's name, task and machinery details. Much more convenient than making notes by hand, and of course these notes stay with the measurement for audit purposes.
The dosimeter can also record the audio during measurements, so you can listen and identify the noise source. This is particularly useful in identifying the cause of unexpectedly high noise levels.
The automatic trigger for recording is user configurable, based on the 1 second sound level, Peak or Max.
The dBadge2 PRO dosimeters record for 10 seconds after triggering, with a pre-trigger of 3 seconds (it records the noise for three seconds before it was triggered). The dBadge2 has enough memory to store a total of 90 minutes of audio.
Audio recordings are stored in standard WAV files, which can be played using the optional Insight software or using the media player included with Windows.
Most noise at work regulations do not demand the use of octave band filters. However, they can be very useful in assessing the nature of the noise, the cause of high levels and in reducing the risk of hearing damage. We recommend octave band filters for areas with very high sound levels or tonal noise.
The PRO version of the dBadge2 includes real-time Octave Band Filters.
Octave Bands split the audible spectrum into bands to provide frequency analysis. For noise at work, these measurements are usually used to assess the suitability of hearing protectors. This method is more detailed and more accurate than the HML method (available from the standard dBadge 2) and more suited to tonal noise.
As octave band analysis requires more power it can be switched on or off as needed.
The dBadge2 will run for 35 hours on a full charge. With the real-time octave band filters running this is reduced to 15 hours, so still long enough for a working shift.
Kits contain dBadge2 PRO Dosimeters with Audio and Octave Band Filters. Kit has dBadges, 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.
