摘要

通过有限元模拟研究了具有 T 型轮廓的屏障的声学特性。研究发现，这种屏障的降噪效率不仅与衍射有关，还与屏障前缘和后缘的声干扰有关。研究表明，与前缘的声音干扰不同，屏障后缘的声音干扰只在距离屏障后表面较短的距离上影响声场。分析了声频和屏障几何尺寸对这些过程的影响。

Sound Level Reduction by T-Shaped Barriers

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.
