A model of an efficient sound absorber with an internal structure consisting of several compact resonators with different parameters is considered. Maximum efficiency is achieved by matching the impedance characteristics of the sound absorber and the acoustic environment. Experimental results on determining the maximum absorption coefficient in the 100-1000 Hz frequency range for test samples made with 3D printing technology are reported. [ABSTRACT FROM AUTHOR] |
