Abstract

Przedmiotem zgłoszenia jest panel akustyczny zawierający wielowarstwowe struktury kryształów fononicznych, charakteryzujący się tym, że zawiera pierwszą płytę perforowaną (11) oraz drugą płytę perforowaną (12), stanowiące płyty czołowe panelu akustycznego; cylindryczne rozpraszacze rozmieszczone w przestrzeni pomiędzy płytami perforowanymi (11, 12), równolegle względem siebie oraz względem płyt perforowanych (11, 12); oraz dźwiękochłonny materiał wypełniający przestrzeń pomiędzy płytami perforowanymi (11, 12), niezajętą przez cylindryczne rozpraszacze.The subject of the application is an acoustic panel containing multi-layer structures of phononic crystals, characterized in that it contains a first perforated plate (11) and a second perforated plate (12), constituting the front plates of the acoustic panel; cylindrical diffusers arranged in the space between the perforated plates (11, 12), parallel to each other and to the perforated plates (11, 12); and sound-absorbing material filling the space between the perforated plates (11, 12), not occupied by cylindrical diffusers.
