Omówiono zagadnienia związane z badaniami laboratoryjnymi urządzeń ochrony przed hałasem oraz ich modelowaniem w algorytmach obliczeniowych. Przedstawiono stosowane procedury badawcze ekranów akustycznych w laboratorium oraz otrzymane na ich podstawie parametry, które posłużyły do modelowania ich właściwości w narzędziach informatycznych. Wyniki obliczeń modelowych przedstawiono w postaci map hałasu...
The paper presents the results of investigation studies involving the impact of atmospheric factors on sound-absorbing parameters of roadside acoustic screen panels. The research studies comprised the aging test consisting of 1000cycles in simulated conditions, sound absorption measurements and surface morphology tests, using the SEM scanning method. The simulation of aging consisted of 100 or 150cycles...
