The doseBadge5 is the next generation doseBadge noise dosimeter from Cirrus.

It provides all of the unique features of the original doseBadge such as no controls, cables or displays with a range of new functions and features allowing it to be used for compliance with any occupational noise standard.

Bluetooth® communication to the dBLink App (for Android and iOS) or the doseBadge5 Wand allows the instrument to be configured and controlled without user intervention.

IMeasurements can be scheduled to start, pause and stop automatically with the timer functions allowing the doseBadge5 to be deployed quickly and easily.

Automatic calibration detection and USB download through the doseBadge5 Dock alongside the secure, robust internal microphone and tap sensor help ensure that your noise measurements are as effective as possible.

  • Data download via USB through the 5 Dock/Charger
  • NoiseTools software supplied as standard for reporting & data analysis
  • User configurable ULT triggers for all channels
  • Visual indication of Dose exceedence with user defined levels
  • Fast & Slow time weightings for RMS channels

Measurement Functions

The doseBadge5 provides simultaneously the following measurement channels:

  • 4 Simultaneous Independent Integrator Channels
  • 2 Simultaneous Independent Peak Channels
  • Configuration of the integrators and peak channels can be chosen from a preset list, for example ISO (LAeq), ISO (LCeq), OSHA HC, OSHA PEL, ACGIH or user configured as needed.

The doseBadge can be used in a wide range of different applications. Below are some examples:

  • The measurement and control of occupational noise exposure
  • Compliance with Noise at Work Regulations, Industrial Hygiene Standards and Occupational Noise Exposure Guidelines.
  • Monitoring and recording of long term noise exposure. Noise exposure measurements in Hazardous environments such as Oil Refineries, Petrochemical Plants and Underground Mines.
  • Measurement of noise exposure in the Entertainment and Music Industries.
