New Dosimeter Dedicated to the Measurement of Noise Exposure

Many workers are exposed daily to occupational noise. Extended exposure of individuals to intense noise levels generates hearing loss and important deafness troubles. In order to monitor the health of individuals exposed to noise as part of their professional activity, 01dB-Metravib (France) has designed the Wed007 sound dosimeter / exposure meter.

Based on an innovating technical solution associated with processing software dBLexd, dosimeter / exposure meter Wed007 fully meets the requirements of European directive 2003/10/EC (regulation relative to the protection of workers against noise exposure). 01dB-Metravib offers a multiple-point metrological approach to assess daily noise exposure. This approach relies on the deployment in the workshop of a set of “blind” dosimeters with wireless (Bluetooth) communication with a Pocket PC. This easy-to-use device is an invaluable tool for the user wishing to implement new regulations on the field.

The Pocket PC is the actual computer-human interface connecting the user with the instruments. It is used to define the measurement configuration of each instrument, to collect acquired data and for the real-time visual display of measured data on its colour screen. For easy field operating, common measurement configurations compliant with current regulations have been pre-programmed in each instrument. The user just has to select the measurement starting date and can thus focus on what matters.
