Noise Assessment
In the last few years, the importance of underwater noise in the environmental impact assessment of vessels, and off shore units has emerged. CO.L.MAR. has completed a number of measurement campaigns all over the world: from Borneo to the North Sea. We have studied many different sources of noise: dredges, “pile driving” operations, speed boats, etc. Proprietary hardware and software has been developed for data acquisition and processing.
A great deal of attention must be paid to data interpretation and to the propagation models, since the measurement conditions are normally far from ideal. It is then necessary to use our wide and specific experience to take the correct consideration, and effects of the measurement conditions encountered in the field.
CO.L.MAR. collaborated for several years with leading Italian research centres involved in marine acoustics, including: ISPRA IRPEM, NURC, CNR, ENEA. Also counts among its clients: Saipem, AGIP, BP, PRYSMIAM, WWF.
