THE EXPERIMENTAL RESEARCH OF THE ACOUSTIC CHARACTERISTICS OF THE AIR NOISE MUFFLER AS A PASSIVE FOUR-POLE

摘要

The results of the experimental researches of the air noise muffler acoustic characteristics (parameters of transfer, input and transfer impedance, losses of transfer, losses of active power and the impendence of the muffler wall), as a passive four-pole (FP), are stated. The method of fulfillment of researches is indicated and the short description of the experimental installation is given.
