"WitrynaAcoustic liners are presently used for attenuating combustion and turbine noise radiated from jet engines. Current acoustic liners are passive by nature. This is a drawback because they are only able to absorb acoustic energy over a limited bandwidth. A possible solution to this drawback is the development of an active acoustic liner.
