impact on marine mammals. The reduction of noise levels when using the vibratory hammer is approximately 15—20 dB and can be larger depending on the pile and soil conditions. However, vibratory driving also has some disadvantages, the most significant being the control and reliability of the bearing capacity achieved with vibrodriven piles.
