Environmental Sound Monitoring

DPS Technical is a resource for comprehensive environmental sound monitoring projects.  Projects for developing noise control plans for motorized activities such as race tracks and motorized recreation facilities are our specialty.

The projects can be straight forward individual special event activities such as air shows, outdoor motorcycle races, indoor arena style events that have a limited need for noise data, or the projects can be part of an environmental assessment program.

We have performed services for a wide variety of projects and are well equipped to function in remote off road locations.  We have capabilities to perform short term site and activity specific projects or more involved continuous fixed location, continuous sound and environmental monitoring.

We have been the contributing research firm for numerous projects including the California Off Highway Vehicle Noise Study, the USDA Helicopter Over flight study and many regional special events.

We have posted additional information in our resource library.

Facility Noise Occupational Safety and Health Monitoring “OSHA” Compliance

Occupational Safety and Health Standards, 29 CFR 1910.95  – Occupational Noise Exposure the sound levels that the employees are being exposed to are identified by a measurement procedure that specifies loudness (volume) Frequency (pitch) and the exposure time, or dose.

We are well equipped and experienced to take accurate measurements in the areas of concern and then utilize the measurement information to help the management team determine what ear protection and other measures are required as directed in the occupational compliance regulations.

Our reports are comprehensive, well documented informational tools for the compliance and loss prevention team.

The attached web link contains information on the regulation and other resources that should provide guidance:

average sound level (TWA) of 85 decibels measured on the A scale or equivalently a dose of fifty percent.
