Original abstract

For theoretical calculation of sound insulation characteristic of the complex structure it is necessary to accept many simplifications. The HAMPPEP – D 13 wood noise barrier with very good acoustics properties has a rather complicated structure. In this paper we present the calculation procedure for such type of barrier. The results of calculation – noise reduction factor R(f) and weighted noise reduction factor Rw are in good agreement with experiment. It implies, that simplified model used for theoretical calculation was adequate.

Czech abstract

Pro teoretický výpočet zvukové izolace složitých struktur je nutné provádět řadu zjednodušení. Protihlukové clony HAMPPEO – D13 s velmi dobrými akustickými vlastnostmi mají složitou strukturu. V příspěvku je uvedena výpočetní postup pro takový typ clon. Výsledky výpočtu – vzduchová neprůzvučnost a vážená vzduchová neprůzvučnost jsou v dobrém souhlasu s experimentem. Z toho vyplývá, že zjednodušený model použitý pro výpočet je vyhovující.
