If you've ever used a power saw in the basement, your family was probably more irritated with the noise than excited about your creation. Imagine what a saw mill sounds like!

Les Wagner, Owner of Wagner Millwork, Inc., , in Owego, New York, didn't have to imagine anything; his compact, efficient sawmill cuts and planes hardwood from raw logs for the furniture industry.

After renovating the building, he found that the new walls and ceilings contributed to a significant increase in noise levels. It was a problem that Les and his insurance company wanted resolved for the comfort and safety of his employees.

He turned to his local Sound Seal representative Bob Andres, of Oshex Associates in Syracuse for help.

Together they assessed the problem. The noisiest part of the operation, the actual sawing, could not be isolated because every piece of equipment had to remain accessible to perform that function. Acoustic enclosures were considered impractical. Instead of isolating the noise at the source, they decided to treat the environment. More than 600 ceiling baffles reduced overall noise levels by 8 db(A). The cost of a standard 2'x4' polywrap baffle is substantially less than any other noise reduction treatment.

Bob recommended that a large quantity of Sound Seal Polywrap Acoustic Baffles be suspended from the ceiling throughout the entire mill. Since the ceiling height was less than ten feet, the suspended baffles placed a great deal of absorption close to the noise sources.

The customer's goal of a 5 dB(A) noise reduction was exceeded. By virtually eliminating reverberation as a factor, noise levels were reduced by approximately 8 dB(A) throughout the entire mill. Even better, the cost of the project was so low that Les was well satisfied.

In fact, Les was so pleased with the results that he arranged for Bob to speak to his colleagues at the Lake Ontario and Lake Erie Swayers and Filers convention. The contacts made during that meeting have led to more work for Oshex Associates and United Process.

Les and his employees now work in a much more comfortable atmosphere. Besides the obvious benefits of increased productivity and a quieter place to work, Les knows that his operation will always be in compliance with OSHA noise standards - and there's a lot of comfort in that!

Sound Seal Polywrap Baffles are an effective tool to improve room acoustics. The cost, even in large quantities, is affordable to virtually any business. Polywrap Baffles are best utilized in applications where they will not be subjected to abrasion or traffic.

You'll find more information about this sometimes overlooked, yet highly effective product on Bulletin SS-107. But in case you need a reminder, the standard Polywrap Baffle comes in white, 2' w. x4' l. x1 1/2" th. with grommets installed for easy hanging.
