I.V.Vovk, V.T.Matsipura, T.A.Sotnikova On one method for increasing the efficiency of the noise-suppressing barriers |
Acoustic bulletin, Vol. 9 ¹ 2, (2006) |
| The improved design of the noise-suppressing barrier is offered. Using the method of partial domains, the efficient numerical-analytical modeling of the sound field scattered by the barrier is conducted. Calculation results are represented in a pictorial graphic form. The advantage of the new barrier type in comparison with the traditional one (in the form of a simple wall) has been demonstrated and proved. |
