Abstract: | A new type of noise silencer with the original design of the air duct-resonator system is proposed. The design is free of the disadvantages that are inherent in the conventional design with a resonator placed inside the air duct. A physical model of the silencer is developed, and its efficiency is calculated for different geometrical and physical parameters of the resonator and the air duct. A comparison between the calculated characteristics and the experimental data is performed, and their agreement is demonstrated. |
