Integral acoustic characteristic of the V-shaped noise-suppressing barrier

Acoustic bulletin, Vol. 10 3, (2007) p.25-29
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.
KEY WORDS:
noise-protecting barrier, open resonator, acoustic power flow, energy efficiency
