Dosimetry

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:

Time history: manufacturing

Peak Measurement: 121.20 dB

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.
