Question

What are some solutions that can help to reduce noise pollution caused by things such as pile-driving? What are some of the drawbacks of these solutions?

Answer 1

A solution that can help to reduce noise pollution caused by things such as pile-driving is air-bubble curtain.

Step-by-step explanation:

• The noise pollution caused by things such as pile-driven into the soil is very high.

• There are many solutions to reduce this noise pollution, air-bubble curtain is one of the useful and simplest solution to reduce noise pollution.

• This solution is based on dynamic sub-structuring technique and modal decomposition method.

• The major drawback of this solution is sound absorption becomes critical, when this method is employed in smaller piles it is because of the radiated acoustic energy is concentrated at higher frequencies than the resonance frequency of the air bubble.
