1. Introduction
Noise induced hearing loss (NIHL) remains one of the world’s leading occupational diseases
and it has been estimated that 16% of global hearing loss is due to occupational noise
exposure. It is acute in the mining, construction, oil & gas sectors but also in a wide variety
of industrial manufacturing and other commercial activities where the cumulative effects of
excessive noise exposure could lead to this avoidable disease.
Noise exposure measurements using a personal noise dosimeter such as dBadge2 is a
recognised method of making an exposure assessment as required by regulations and/or
standards such as CFR 1910.95 Occupational noise exposure (USA), ISO9612:2009
Acoustics – Determination of occupational noise exposure – Engineering method, HSE
Document L108 Controlling Noise at Work – Guidance on Regulations.
The original dBadge proved an invaluable tool in monitoring personal exposure but dBadge2
is the next generation, taking all of those features and usability and building on them; a true
evolution. New features of the dBadge2 include:
Full colour display with colour-coded screens and alarms
Bluetooth® 4.0 wireless connectivity
Airwave App for mobile devices such as smartphones & tablets
Multiple simulated dosimeters (termed D1, D2 & D3)
Motion sensor
1 second time history profiling
Pause function
Recording of audio events (Plus & Pro models)
Real-time octave band frequency analysis (Pro model only)
USB download via Docking Station (and combined charger)
Updated & simplified Plug-in for Casella Insight data management software
The models and other key features of the dBadge2 range are listed below:
The addition of Bluetooth® 4.0 wireless connectivity and the supporting Airwave App
enables remote control and monitoring of the instrument’s status such as battery usage,
memory capacity and measurement progress without having to disturb the worker. This
added confidence in the measurement minimises the likelihood of having to repeat a survey
due to potentially flawed data and therefore maximises your productivity.
