Novelty Test Report VII - Sand

If jet fuel prices are keeping you from traveling to the beach this year, Riverbank has you covered!

While we can’t bring the ocean to Geneva, we can bring a little bit of the beach into our reverberation chamber. For this latest installment of Riverbank’s Novelty Testing Series, we tested approximately 5-1/2 inches of fine mason sand to determine its sound absorption coefficients across a wide range of frequencies using ASTM C423 procedures.

Although sand is more commonly associated with vacations, volleyball courts, and sandcastles, the results demonstrated surprisingly strong acoustical performance. Check out our latest novelty test report to learn more about the acoustical behavior of sand and see the full test results.

RAL will be performing a series of self-sponsored tests and publishing the results for wide dissemination across the acoustics community. Send us your suggestions for our next test! We are looking to test commodity materials or systems where data is needed but does not exist due to a lack of a traditional sponsor.

The Rules:

• Test samples should be made from commodity materials, no specific acoustical product systems
  
• The tests would not have a conventional sponsor interest, so they are not likely to happen in the acoustical testing marketplace
• The results have some utility or interest to the broad acoustics community
