Assessment of contribution of shipping sound to Dutch underwater soundscape. Shipping sound is largest contributor to underwater noise in Dutch North Sea soundscape at frequencies below 10KHz. Estimation of sound pressure levels and total acoustic energy made from 1948 to 2035. doubling of energy predicted between 1965 and 2000. expected 15% rise in total acoustic energy predicted until 2036. This energy could be decreased by: relocation of shipping routes, speed limits, and more silent ships in the future. As an example, sound maps are calculated for ICES 209 research vessels to provide an insight into a possible way to decrease the shipping sound in the Dutch North Sea.
