Questions & Answers:

Will the vent reduce sound from inside to outside as well as from outside to inside?
The BRE has advised us that it’s reasonable to assume that ‘reciprocity’ applies to the vents. That is, the third octave values for sound reduction index are the same in both directions (out to in and in to out).
