Abstract
This paper presents the results of numerical modeling of the penetration of a sonic boom into a room through a building window. The calculation results are validated by field measurements of a sonic boom caused by a supersonic aircraft flying at cruising altitude. It is found that the main transmission mechanism is the displacement of the window frame in the window opening as a whole, and not the excitation of the first natural mode of the window. The influence of the stiffness and damping of the sealing of the window unit in the window opening on the passage of a sonic boom is studied. It is found that an increase in both of these parameters significantly reduces the amplitude of the sonic boom inside the room.
