Abstract

1. Звукоизолирующий листовой материал, содержащий в слоистой сборке а) основной звукопоглощающий листовой материал и б) плотную пористую мембрану, при этом мембрана характеризуется i) сопротивлением воздушному потоку примерно 10000 рейл или менее и ii) коэффициентом акустического качества, как определено здесь, по меньшей мере примерно 3000. ! 2. Листовой материал по п.1, отличающийся тем, что мембрана имеет толщину 150 микрометров или менее. ! 3. Листовой материал по п.1 или 2, отличающийся тем, что мембрана характеризуется коэффициентом акустического качества по меньшей мере 10000. ! 4. Листовой материал п.1 или 2, отличающийся тем, что мембрана характеризуется коэффициентом сопротивления воздушному потоку примерно 2000 рейл или менее. ! 5. Способ звукоизоляции пространства, содержащий этап, на котором устанавливают в двумерной матрице по воздушному проему и в положении, обеспечивающем ослабление шума от источника шума, плотную пористую самоподдерживающуюся мембрану, характеризующуюся сопротивлением воздушному потоку примерно 5000 рейл или менее и коэффициентом акустического качества по меньшей мере 3000. ! 6. Способ по п.5, отличающийся тем, что дополнительно содержит этап, на котором устанавливают более воздушный, нетканый волоконный листовой материал в слоистой сборке с мембраной.
