Numer_referencyjny_programu_pomocowego: SA.41471(2015/X) Przeznaczenie_pomocy_publicznej:art. 25 rozporządzenia KE nr 651/2014 z dnia 17 czerwca 2014 r. uznające niektóre rodzaje pomocy za zgodne z rynkiem wewnętrznym w stosowaniu art. 107 i 108 Traktatu (Dz. Urz. UE L 187/1 z 26.06.2014). Celem projektu jest opracowanie prototypu innowacyjnej bariery akustycznej umożliwiającej tłumienie hałasu z obiektów sieci gazowej GAZ-SYSTEM S.A. Prototyp będzie składał się ze struktur równomiernie rozmieszczonych w przestrzeni rozpraszaczy dźwięku z wykorzystaniem dodatkowych lokalnych zjawisk rezonansu i pochłaniania dźwięku (tzw. struktury kryształów sonicznych). Najważniejszą cechą takich struktur z punktu widzenia tłumienia hałasu jest zjawisko występowania tzw. przerw pasmowych – zakresów częstotliwości, w których fala akustyczna nie jest propagowana w strukturze. W obiektach sieci gazowej, w szczególności w halach sprężarek tłoczni gazu, występuje hałas z wyraźnymi składowymi tonalnymi w zakresie średnich i wysokich częstotliwości. Hałas ten przedostaje się na zewnątrz obiektów a obecnie stosowane rozwiązania w postaci tłumików akustycznych w instalacjach wentylacyjnych nie dają zadowalających rezultatów dla wąskopasmowych składowych częstotliwościowych. Innowacyjną cechą bariery akustycznej z wykorzystaniem struktur kryształów sonicznych jest zdolność do redukcji hałasu w określonych wąskich pasmach częstotliwości, przy czym nie są to przegrody ciągłe i umożliwiają przepływ powietrza przez swoją strukturę i dają możliwości montażu w bezpośrednim położeniu instalacji wentylacyjnych (wycieki hałasu), w tym również w strefie zagrożenia wybuchem. Założony cel projektu zostanie osiągnięty przez realizację badań przemysłowych obejmujących m.in. szczegółowe analizy akustyczne obiektów tłoczni gazu niezbędne do opracowania modeli oraz prototypu rozwiązania technicznego i realizację prac rozwojowych obejmujących m.in. demonstrację prototypu bariery akustycznej.
