Postoji srednja apsorpcija sobe:
Mean Absorption Coefficient
The mean absorption coefficient for the room can be expressed as:
am = A / S
where
am = mean absorption coefficient
A = the absorption of the room (m2 Sabine)
S = total surface in the room (m2)
pa po tome, da sve povrsine pokrijes jednom tablom azme od 2cm, dobices srednji apsorpcioni koeficijent kakav si imao i na pocetku.
Apsorpcioni koeficijent NE moze biti veci od 1... barem po definiciji. Maksimalni apsorpcioni koeficijent ima "otvoren prozor"... sve sto "udari u njega... izadje napolje i
nikada se ne vrati (teorija!)
Dalje sta moze biti zanimljivo je:
Room Constant
The room constant express an acoustic property of the room:
R = A / (1- αm) = Σ Si αi / (1- αm)
where
R = room constant (m2 Sabine)
A = absorption of the room (m2 Sabine)
αm = mean absorption coefficient of the room
Si = individual surface area in the room (m2)
αi = absorption coefficient for individual surface in the room
