The Oregon Department of Transportation (ODOT) Environmental Services Unit evaluates the impacts of noise and mitigation of noise issues. ODOT currently requires noise level evaluaton for proposed construction projctgs when threatened or endangered wildlife may be adversely affected. A commonly used piece of equipment on construction projects is the guardrail post driver. The guardrail post driver does not have a baseline noise level established. As a substitute, ODOT biologists have used the baseline noise level associated with the pile driver for noise level assessments. This study establishes a more accurate baseline noise level for the guardrail post driver, which is lower than the baseline noise level of the pile driver. Due to this lower noise level, there is a potential increase in safety and decrease in cost.
