Abstract
FIELD: emergency communications engineering.SUBSTANCE: novelty is introduction of hollow metal cylinders closed on ends with acoustically permeable water-tight material which are installed in pairs in compartment-to-compartment bulkheads so that their butt ends occur in adjacent compartments at distances multiple of (2N - 1)λ/4, where N is integer number; λ is operating wavelength.EFFECT: enhanced operating reliability.1 cl, 1 dwg
