ACOUSTICS SOFTWARE For
is a powerful Software tool for Acoustics
Engineers & Architects.
Based on Mathematical calculations, it
determines the acoustical parameters of a room,
such as the reverberation time.

Formula is applicable to all rooms where diffused
conditions of sound exist.
This formula is more universal in application than
any other formula.
Effect Of Shape Of the Room
Reverberation Formulae are based on statistical
calculations, using the total room volume and the
total absorption present, assuming a diffuse sound
reverberation time depends on the mean free path.
The formula we used considers the room
shape as rectangular.
This mean free path varies with different
