Title: | Research on mathematical modeling of acoustic intensity corresponding industrial sources in order to cut noise pollution | Authors: | Bratu, Mihai | Keywords: | Noise pollution;Mathematical modeling;Composite materials | Issue Date: | 2012 | Abstract: | 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. |
