Required for two purposes; to prevent external noise from compromising the carefully engineered reproduction of subtle sound pressure
level (SPL) within the theater room, and to prevent high SPL inside the theater escaping and disturbing adjacent areas and rooms.
We use wall construction guidelines for proper isolation, including but not limited to:
• Mass & thickness of inner & outer wall surfaces
• Acoustical damping layer between both walls
• Providing air gaps for lowing energy transmission, especially for low frequencies
