Wood frame building noise.

Footstep or impact noise is observed both in buildings of concrete construction and wood frame construction.

Although it is common to add noise barriers within light wood frame assemblies e g batt insulation in a floor cavity this method is much less common in mass timber assemblies. This is a catch up since most european union and several north american jurisdictions including british columbia already allow six storey wood frame.
