The Response of Irregular Enclosure with Different Excitation

Abstract:

This paper presents a theoretical investigation into the response of the coupled system which consists of a regular or irregular enclosure with different excitation, including noise reduction level and panel vibration energy level. The results show that the noise reduction level curves appear changes in medium and high frequency region when the enclosure change from regular rectangular to irregular trapezoidal, but there is small variation in panel vibration energy. Compared with the incident plane wave perpendicular to the flexible wall, more panel modes are excited by the oblique plane wave, and it means that more noise go through the flexible wall into the enclosure.
