The doseBadge is a unique solution for Personal Noise measurements. The new CR:100B version of the doseBadge provides not only the measurements essential for compliance with Occupational Noise regulations, but with the new RC:100B Reader unit it can store up to 24 hours of LAeq Time History data including Peak(C) and Overload exceedences. In addition to the new hardware, a suite of software is available to suport the new features and functions.


  • Measurement of Personal Noise Exposure
  • Assessing and Monitoring noise in the workplace
  • Ensuring compliance with Noise at Work regulations


The doseBadge is a unique solution to the problems associated with the measurement of Personal Noise Exposure. The doseBadge itself has no controls or cables which means that the unit can be used in situations where the wearer is working in confined spaces or where there is a risk of a cable being caught in machinery.

The doseBadge can only be operated (reset, calibrated, started and stopped) using the Reader unit or the Keyfob remote control. This dramatically reduces the possibility of the wearer tampering with the unit. The small size and light weight design of the doseBadge also reduces the risk of damage to the unit.

The measurements provided the doseBadge have been designed to allow full compliance with Noise at Work regulations, while giving a simple output that can be easily understood.

The design of the doseBadge allows the case to be much smaller than a conventional dosimeter. This ensures that the movement of the user is not constricted by cables and connectors. The unit has no controls or switches, with all functions controlled by either the RC:100B Reader unit, or by the RC:101B Keyfob Controller. The rechargable battery is sealed within the unit and is charged using the reader unit or by additional charging blocks.

The RC:100B Reader can store up to 255 measurements, from any number of doseBadges. For example, the user can start a system with a single badge, a reader and a power supply.

The CR:100B doseBadge Personal Noise Dosimeter and the RC:100B Reader Unit have been designed to meet the requirements of IEC 61252:1993 Personal Sound Exposure Meters and the ANSI S1.25:1991 Personal Noise Dosimeters. The CR:100B doseBadge and the RC:100B Reader unit must be used as a combination to ensure compliance with these standards.
