Design of Noise Barrier Based on Different Frequencies (a) Low Frequency Noise Barrier Configuration (b) Middle Frequency Noise Barrier Configuration and (c) High Frequency Noise Barrier Configuration

First time in the world frequency based noise barrier has been developed to kill the disturbing frequency of the existing noise.

Development of any infrastructure having its major drawbacks in the shape of noise pollution either in a city or in forest areas. Railways, highways or aviation contributes to approximately 72% noise pollution. For control of the noise pollution different types of frequency based noise barriers has been developed. It will kill the actual disturbing noise frequencies accordingly. it will be highly useful for urban areas where there is a noise hotspots and highway and railway passing through them. for the protection of human and animal health these newly developed frequency based noise barriers are highly useful.

Present invention is related too novel design of a noise barrier based on different frequency. The design is based on the principle of identifying the disturbing frequencies generated from transport sector. The specific frequencies are grouped into low, middle and high frequency ranges. noise barriers are designed to specifically kill those disturbing frequencies. this invention is best suited for railways, metro etc where itching noise is a biggest problem on the curve portion. this is also best suitable for road intersections where honking is the biggest problem.
