Underwater noise barrier

Environment

Objectives

The construction of an underwater noise barrier has been simplified through the use of acoustics simulation to compare different configurations of the barrier.
It is made of non-organic materials that have high damping characteristics for sound waves, and it is aimed at protecting marine wildlife from construction work on the seashore.

Results and information extracted

The simulation objective was to minimise the consumption of raw materials and keep an efficient noise attenuation.

The results confirm that one configuration can use twice less raw material than the original one and still be as efficient.

Initial noise barrier

The images show the sound wave that propagates until it is blocked by the designed barrier.

Final noise barrier

The second barrier is as efficient as the first one with twice less raw material.
