atenuarea zgomotului produs prin rezonanta

Vagoanele de marfa inchise, actioneaza, dpdv al propagarii sunetului, ca o cutie de rezonanta. De fapt ceva asemanator unei cutii de vioara, datorita peretilor de plastic care vibreaza, sunetul este apmlificat in interior si propagat prin peretii flexibili ai vagoanelor!
Am redus acest zgomoto suparator printr-un proces lung, elaborat si multi complexe de…. umplere cu vata a cutiei!Very Happy
Incercati si voi! Veti observa imediat schimbarea in acustica vagonului!
