Taj mi dio nije jasan kada prema formuli na http://www.audioholics.com/education...onant-absorber http://www.audioholics.com/education...onant-absorber...
Dobivam da je :
S=L*V*((f*pi)/0,5*c))2 ... 2 označava "na kvadrat"
...odnosno ...

V=(L*((f*pi)/0,5*c))2) / S

Where f is the resonant frequency (Hz), c is the speed of sound (1120ft/s), pi =3.14, S is the area of the port (ft 2 ), L is the length of the port (ft), and V is the cavity volume (ft 3 ).

Gdjer mi je i dalje S nepoznanica. Zar za S uzmem da mi je površina unutarnjeg ruba cijevi ??? To me muči ...
