1-4 The Edge Personal Noise Dosimeter Model EG-4P User Manual
Applications of the Edge
The Edge has a cable-free, mounted microphone that converts sound
pressure into an electrical signal. This signal is conditioned, monitored,
and integrated over time in order to provide a host of automatically
calculated values that can be used in occupational and environmental
noise assessments. Programmable parameters permit the Edge to serve
many applications. The Edge can be used in the following applications:
As a personal noise dosimeter—used to measure a worker's daily
exposure to noise levels. This information can be used to ensure
compliance with OSHA, MSHA, ACGIH, IEC, or your own
customized parameter settings to determine if your workers are
over-exposed to noise.
As a time-history monitor—used to provide a worker's minute-by-
minute noise exposure levels. This data can help you identify major
contributors to the average daily noise exposure.
As a survey monitor
Throughout a plant/facility—used to oversee noise levels
throughout an entire facility. You can identify machines and
equipment which produce harmful noise levels.
Specific areas in a plant/facility—used to identify key areas as
“noisy” and implement noise control options. Employees may be
exposed to unacceptable noise levels.
As a peak dosimeter—used to detect the highest level of
instantaneous sound pressure.
