The assessment is completed to collection information regarding noise and how it impacts your facility. It involves gathering information from managers and employees, taking sound level measurements to model the noise sources, collecting physical measurements and photographs of equipment and spaces.

Gathering information from the people who know the conditions best and work with the equipment everyday will allow us to engineer a solution that will mitigate the noise without restricting operations.  

It is the combination of your knowledge regarding the operation of the facility and our knowledge regarding engineering acoustics that will lead to an effective noise solution.  An initial meeting to review facility plans and an education to our team on the process and procedures your your facility is usally a good starting point.

In most facilities dosemeter measurements to document noise exposure to key personal have been previously completed.  This information can be helpful in identifying the amount of noise reduction needed and the primary areas of concern for mitigation.  During our assessment measurements will be made of these noise sources to collect frequency-specific octave band data.  For a typical piece of equipment these measurments will be made at six-points around the source to document the directivity of the source. These measures will be used to build a three-dimensional model of the space and equipment to evaluate treatments.

Untilizing 2-channel or an 8-channel spectrum analyzer we can map a space for noise levels, each measurement documenting 32 frequencies of the noise source.  As we build our computer model from source measurements, these measurements can be compared against the computer to document the accuracy of our predictions.

By the end of our assessment visit to your facility we will have a clear understanding of your noise issues.  We will have reviewed your concerns, established a clear goal for noise control, met with key personnel, collected available drawings, equipment manuals, and plant operating procedures, taken sound level measurements, and photographed and maped the spaces for our evaluation.

Typically, for a single space, this visit is completed in one day!
