STUDY FOR REDUCING NOISE POLLUTION OF THE MARINE ENVIRONMENT BY INTRODUCING NOISE AT THE ACOUSTIC SOURCE

This paper presents a virtual instrument and a simulation in order to reduce the noise produced by rig tenders. Underwater noise sources cause environmental pollution, with damage to marine life habitat, their communication, disrupting the feeding area, with economic repercussions on the number of fish and the fishing activity. Measurement of sound power level of these noise sources has led to the conclusion that the highest level, according to 120 dB re 1 mu Pa criterion was extended to 3-5 km distance from the platform. Virtual instruments were built by the phenomenon of composition leads to attenuation of sound waves in the vicinity of marine platforms. Project which measurements were made, the system of acoustic measurement / recording / transmitting, the mobile polygon, the virtual instrumentation are a personal contribution to the efforts to reduce the noise pollution of the marine environment.
