A hydraulic noise suppressor for reducing water-borne noise, and method for handling the same, especially in the area of a construction site when an object is driven into underwater soil. The hydraulic noise suppressor can have at least two rigid holding elements, at least one support structure, and noise reducing elements secured to the at least one support structure, an upper end of the at least one support structure being secured to at least one of the at least two holding elements. The hydraulic noise suppressor can be divided along lateral flanks extending between the upper end and an opposite lower end of the at least one support structure.
