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
1. Throughout a plant/facility – used to oversee noise levels
throughout an entire facility. You can identify machines and
equipment which produce harmful noise levels.
2. 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.
