Noise reduction through bubble veil
Noise reduction for blast operations and underwater construction
A bubble veil can also be used to muffle a blast wave caused by underwater blasting or construction work. In this case, it is not the flow pattern created by the bubble system that is utilized, but rather the fact that bubbles serve as muffler. The energy of the blast wave can actually not be reduced since the bubbles cannot absorb its energy. However, the maximal amplitude can be reduced significantly.
This method requires high amounts of pressured air. This is not necessarily economic. However it is oftentimes more reasonable because the application also protects wildlife.
