Abstract

Element dzwiekochlonny, sklada sie z czesci bazowej (1) bedacej materialem dzwiekochlonnym i zespolu rezonansowych ukladów akustycznych (2, 3). Parametry czesci skladowych dobrane sa tak, aby poszerzyc pasmo lub zwiekszyc w wybranych podpasmach chlonnosc akustyczna wprowadzana przez czesc bazowa. Czesci polaczone sa w taki sposób, ze zarówno powierzchnia materialu dzwiekochlonnego, jak i apertury rezonatorów wystawione sa na oddzialywanie fali akustycznej.The sound-absorbing element consists of the base part (1) being the sound-absorbing material and a set of resonant acoustic systems (2, 3). The parameters of the components are selected so as to broaden the band or increase in selected subbands the acoustic absorption introduced by the base part. The parts are connected in such a way that both the surface of the absorbing material and the aperture of the resonators are exposed to acoustic waves.
