Abstract
The paper reviews the existing methods for measuring the acoustic characteristics of sound-absorbing materials. The description of the used test bench for measuring the acoustic characteristics of materials by the three-microphone method is given. The results of the test measurements of the fibrous sound-absorbing material characteristics carried out at this test bench are presented. The analysis of the obtained results is carried out.
