Hello together,
i would like to make 1/4 of my room
complete death.
What ist the absorption coefficient of
12" 703 glassfiberboard (spacing 5" out from wall)
in the lower frequency at 40Hz and 80Hz???
Thanks for answers
:shock:

Using some realistic extrapolation, 1.00 at both frequencies for random incidence and around 0.7@40 Hz and 0.9@80 Hz for normal incidence.
