Directivity of tire/road noise emission for selected tires and pavements
PublicationPraca pośwoęcona jest kierunkowości emisji hałasu opon i nawierzchni drogowych. Opony są dominującym źródłem haasu w pojaździe poruszającym się w typowych warunkach ruchu drogowego. Hałas ten nie jest bezkierunkowy jak to przyjmuje się w modelach obliczeniowych hałasu. Takie założenia wynikają z ograniczonej dostępności danych dotyczących kierunkowości i mogą prowadzić do niedokładności przy prognozowaniu hałasu drogowego. Praca...
