Substantial amounts of broadband noise are generated by jet engines which can produce 120dB of noise during take-off.

Oscar has proven in wind tunnel model tests that engine noise can be reduced by 7dB by the application of its technology with no effect on aerodynamic performance.

This reduction in noise occurs in the frequency range to which the human ear is most susceptible.

The technology, once adopted by plane operators and engine manufacturers, will have a major beneficial effect on the levels of noise pollution around airports, allowing operators to comply with noise regulations and improving the lives of people living close to airports.
