• Abstract:
  There is growing concern about noise levels from pile driving activities associated with the ; construction of highway bridges and other in-water structures. It has been demonstrated that noise ; generated from pile driving with an impact hammer can be harmful to aquatic species protected by the ; state and federal Endangered Species Act (ESA). To comply with current environmental regulations ; and noise level attenuation criteria, ODOT needs to develop hydro-acoustic monitoring protocol and ; predictive models so projects can develop appropriate sound attenuation strategies based on site ; specific conditions. ; This research project addresses several concerns related to hydro-acoustic impacts and will ultimately ; help highway projects stay in compliance with established noise level criteria. The research project ; included: 1) identification of sound generation mechanisms from pile driving and how sound ; propagates into the surrounding underwater environment, 2) development of an acoustic monitoring ; procedure and predictive model that will help assure compliance and 3) validation and verification of ; predictive models.
