        "text": "Sound flanking occurs when acoustic energy bypasses a soundproof wall or ceiling by traveling through indirect paths like ductwork, floorboards, or shared plumbing chases. Even if a partition has high sound isolation, sound can escape through unsealed perimeter edges, back-to-back electrical boxes, ceiling registers, or hollow doors. Process clarity during installation is critical: contractors use non-hardening acoustical sealant along every wall-to-floor and wall-to-ceiling perimeter joint to maintain an airtight seal. Putty pads are wrapped around junction boxes inside the wall cavity to stop air leaks. If flanking paths are ignored, the perceived sound reduction of the room drops drastically.",
