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.
