This project is devising a new underwater sound level meter (USLM) for WSDOT that will incorporate improvements to current design. These improvements will include a more efficient casing with protected (indented) cable connection ports, a longer recording period over which continuous measurements can be taken, and updated PC software capable of operating with Windows 10. The new software will have attributes for impact and vibratory pile driving that align with NOAA’s most recent Marine Mammal Acoustic Technical Guidance.
