A SoundSense Patented Acoustic Muffler to eliminate acoustic leakage from recessed lights and other openings in a ceiling or wall

摘要

In 2011 SoundSense received a patent for an acoustic muffler that solves the problem of significant sound energy transmission, or acoustic leakage, through openings in a ceiling or wall structure, such as a recessed light. Objects that create a hole or opening in the structure in which they reside can significantly reduce the STC (Sound Transmission Class) and/or IIC (Impact Insulation Class) of the structure. A standard acoustic enclosure cannot be used on a heat generating unit, such as a recessed light, to solve an acoustic leakage problem. This is because there is substantial heat build-up when the heat generating unit is enclosed, causing a recessed light to strobe, or a projector to fail. The SoundSense acoustic muffler prevents acoustic leakage through an opening in a ceiling or wall, such as a recessed light, that would potentially cause acoustic failure of the structure, while simultaneously allowing for the required air flow. The muffler aids the engineer and architect to specify that a ceiling or wall will meet building and noise code requirements. The SoundSense muffler is also easy to install. Additionally, the muffler is class A fire rated and has achieved a fire rating of almost 2 hours.
