An “interferometr” installation with a normal incidence of sound waves has been created in the laboratory of “Vibroacoustics and acoustic design of aviation technology” at MAI to study the acoustic characteristics of sound-absorbing materials and structures. The equipment and main characteristics of the created installation are not inferior to the leading analogues of Bruel&Kjaer, BSWA, Mecanum, Acoustic Awareness, Müller-BBM Industry Solutions GmbH, as well as previously developed and used in the Russian Federation. A comparison was made of the acoustic characteristics of samples of sound-absorbing structures and materials similar in geometric parameters, obtained at the MAI “interferometer” installation and data published in the open press.
