I.V.Vovk, T.A.Sotnikova Integral acoustic characteristic of the V-shaped noise-suppressing barrier |
Acoustic bulletin, Vol. 10 ¹ 3, (2007) |
| An integral criterion, allowing the estimation of noise-suppressing properties of the acoustic barriers, is offered. Efficiencies of noise-suppressing by the classic and the V-shaped barriers are compared. The expedience of practical using of the V-shaped barriers is shown. |
