- Title
Sound Level Reduction by T-Shaped Barriers.
- Authors
Komkin, A. I.; Musaeva, R. N.
- Abstract
The acoustic characteristics of barriers with a T-shaped profile are studied by finite element simulation. It has been found that the sound reduction efficiency of this barrier is related not only to diffraction, but also to sound interference at the leading and trailing edges of the barrier. It is shown that the sound interference at the trailing edge of the barrier, in contrast to the sound interference at the leading edge, affects the sound field only at short distances from the rear surface of the barrier. The influence of the sound frequency and geometrical dimensions of the barrier on these processes is analyzed.
