Noise Control System: Bottom side ceiling

• The joist assembly provides the foundation of a bottom side noise control system designed according to “MASS-SPRING-MASS” physics.
• A Resilient Channel is the spring and isolation device.
• The gypsum board is the bottom Mass

Noise Control System: Wall/Ceiling interface

• Critical that the ceiling does not contact the wall to avoid flanking path.
• Standard is to “float” the wall up to the ceiling, however, installations are very poor.
• Space Assurance provides a simple method to maintain the acoustical performance of the system.
