摘要: The physical properties of a periodic distribution absorbent resonators is used in this work to design tunable wideband bandstop acoustic filter. Analytical and numerical simulations as well experimental validations show that the control resonances absorption scatterers along with their arrangement air introduces high technological possibilities noise. Sound manipulation perhaps most obvious application structures presented work. We apply methodology develop device an alternative conventional barriers several from acoustical point view but also additional aesthetic constructive characteristics.
