Underwater Noise Reduction of Marine Pile Driving Using a Double Pile

The final research report from our 2014 full scale acoustic test in Commencement Bay is now available (finally).  Thank you for your patience!

You can download the full report here on the WSDOT website.

"This new research shows we can minimize underwater pile driving noise to avoid harm to mammals and other protected marine species. The new sound attenuation method may also save project construction time and money."
Rhonda Brooks, Research Director, Washington State Department of Transportation

Hear the difference

Recorded from hydrophone deployed at 10m during subscale testing of 8" steel piles in Seattle, Washington in 2013.

You are hearing 4 strikes of a standard pile followed by 4 strikes of a Reinhall Pile™. Notice the difference.
