Brza procjena vremena odjeka


Nakon prestanka emitiranja zvuk u prostoriji počinje slabiti jer plohe apsorbiraju zvučnu energiju. U prostoriji s više refleksijskih ploha zvuk će slabiti duže vrijeme, a u prostoriji s mnogo apsorpcije to vrijeme bit će mnogo kraće. Međutim, vrijeme potrebno za slabljenje zvuka do nečujnosti ovisi i o tome kolika je početna glasnoća, kolika je buka u prostoriji i kakvo je stanje organa sluha. Kako bi se osigurala normirajuća vrijednost uveden je pojam vremena odjeka, a to je vrijeme potrebno da zvučna energija u prostoriji oslabi 60 dB. Poznavanjem vrijednosti apsorpcijskih koeficijenata različitih materijala lako možemo procijeniti vrijeme odjeka, a točnost ovisi o mnogim parametrima (podudarnost ugrađenog materijala i korištenog modela, kut upada zvučne energije, itd.)

Proračun vremena odjeka

Približno vrijeme odjeka može se brzo izračunati Sabineovom formulom:

RT60=0.161 V / A

gdje je: V - volumen prostorije, A - apsorpcija jednaka umnošku površine i pripadajućeg koeficijenta apsorpcije αsr prema tablici:

A = S αsr

Napomena: ako je na nekoj plohi primijenjeno više od jednog materijala npr. na stropu je 50% fiberglasa debljine 5 cm s koeficijentom (iz tablice materijali za strop) α=0.8 i 50% drvene šperploče debljine 2 cm s koeficijentom α=0.17; jednostavno ćemo pridjeliti stropu koeficijent apsorpcije (0.17+0.8):2=0.485

Napomena: ako neparalelopipednu prostoriju aproksimiramo paralelopipednom, na isti volumen, procijenjeno vrijeme odjeka bit će duže od stvarnoga jer neparalelopipedna prostorija ima veće oplošje pa i veću ukupnu apsorpciju.

Analiza prostorije

Visine H =m = ft

Dužine L =m = ft

Širine W =m = ft

apsorpcijski koeficijent:

azidova=, apoda =, astropa = ---> asrednje =
daje efektivnu apsorpcijsku površinu Se =m2 = ft2
za prostoriju volumena V =m3 = ft3.
Procijenjeno vrijeme odjeka je RT60 =sekundi.
