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.
