Acoustics manufacturer Illbruck Acoustic debuted Prospec Decibel Drop, a viscoelastic damping compound that the company says decreases the sound traveling to adjacent rooms.
It is suitable for use in broadcast facilities and is Class 1 fire-rated.
Prospec Decibel Drop provides acoustic control in low frequencies, and has a sound transmission class rating of 50 to 62, depending on construction configuration. It is installed between layers of drywall or plywood in walls and ceilings, or between layers of subflooring.
It comes in a cartridge and is applied with a standard caulk gun. Two to three cartridges cover 32 square feet, applied randomly over the drywall surface area.
