“…One of the major components of the harmful impact of aviation on the environment is the noise created by aircraft. One of the most effective ways to reduce the noise of aircraft propulsion systems is to include sound-absorbing structures (SAS) in its composition [1]. SAS represent a set of Helmholtz resonators, allocated in the form of a honeycomb structure made of polymer composite materials.…”

“…Multilayer honeycomb panels of resonance type SAS allow to reduce the noise in a wide range of frequencies, thanks to the operation of resonators tuned to different frequencies [1]. At the first stage of the SAS developing process, the direct and inverse problems of determining the impedance by geometric parameters were solved.…”
