Why Acoustical Performance
Did you know...
Adding insulation to wall or ceiling assemblies can boost the acoustical rating of the system by up to 35%.
Did you know...
Understanding your goals up front is key to building the right solution. For instance, solutions for managing in-room acoustics could vary drastically from managing room-to-room noise. Insulation can help achieve goals for both instances.
Why Insulation Matters
While insulation plays a major role in managing sound in an assembly, it can’t stand alone. Individual products do not have acoustical ratings, but instead are rated together as an entire system. Don’t be fooled by misleading claims, and be sure to take into account all components to ensure acoustically comfortable spaces.

Studies show that noise is a top complaint among hotel guests. Ironically, guests complain about noise to hotel management in only about half of all cases. This leaves hotel management with unhappy guests and without the information they need to recognize the severity of the problem and address it properly.

When ambient noise in a hospital reaches 65 decibels (dB), the risk of a patient suffering a heart attack increases. This is especially concerning as noise levels in some hospitals have been measured as high as 95 dB —roughly equivalent to the sound of a subway train at 200 feet.

Once sound becomes disruptive, it is classified as noise. This noise carries with it a variety of harmful effects—many of which we may not even realize. This is where the role of acoustics comes into play in creating spaces where we can optimize how people learn, work and heal—and the effects are considerable.
