Research on mathematical modeling of acoustic intensity corresponding industrial sources in order to cut noise pollution

There has been research on mathematical modeling of acoustic intensity emitted by industrial sources, obtaining new materials with properties that will be used as sound-absorbing barriers attenuators for sound waves. They conducted research on mitigating noise from a source that emits sound in the frequency band between 250 Hz and 8000 Hz. Noise barrier is used as a sample of composite material made of polyester resin reinforced with rubber powder. According to the graphs, there is a significant reduction of noise, resulting in the fact that this type of composite material is a good muffler; resulting in less sound pressure level due to sound-absorbing properties of the new type of composite material and compliance with the limits of law; computer simulation program and drawing paper confirms a material obtained acoustic barriers to achieve soundproofing and noise reduction in industrial areas.
