Overview
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.
Peak Measurement: 121.20 dB
