ISO 717: Sound Insulation Rating Systems (Rw, STC, Dnt,w) Decoded
Decode ISO 717 sound insulation ratings — how Rw, STC, DnT,w, and L'nT,w are calculated, why lab and field values differ, and how to avoid the flanking transmission trap.
What is Noise Path Analysis? Tracing Sound from Source to Receiver
Noise path analysis identifies every route sound takes from a source to a receiver — direct, flanking, airborne, and structure-borne. Learn the method, ISO 12354, and how it drives cost-effective fixes.
What is Structure-Borne Sound? When Buildings Conduct Noise
Structure-borne sound travels through building elements as vibration before radiating as airborne noise. Learn transmission mechanisms, measurement methods, and isolation strategies.
Flanking Transmission — Why Your STC 60 Wall Performs Like STC 35 | AcousPlan
Flanking paths through floors, ceilings, and ducts reduce a lab STC 60 wall to field FSTC 35. ISO 15712 prediction method with 5 flanking path examples.
What Is Flanking Transmission? — Why Your Wall's STC Rating Doesn't Matter
Flanking transmission is sound that bypasses a partition by travelling through connected structure — floors, ceilings, ducts, or walls — and it routinely cuts field STC by 10 points or more. Here is how to find and stop it.
