Reduction of patient stress
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.

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.

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.

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.

In classrooms, if students can’t hear they can’t learn. A 20 dB increase in classroom noise has been shown to delay a student’s reading level by up to eight months.
The Role of Acoustics
Reduces exterior noise
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.

With the increasing popularity of open-concept spaces bedrooms have become a shelter from the hustle and bustle of your active home. The bedroom is where you start and end each day, where you go to relax, unwind and recharge so creating a comfortable bedroom environment contributes to a good night's rest and your overall quality of life.
The key to minimizing unwanted sounds is to use the right products and systems, but it's important first to understand the science behind sound.
Impact Insulation Class (IIC) measures floor-to-ceiling impact sound transmission. The higher the IIC rating, the better.

Specs
This rigid fiber glass board is used for applications requiring an exposed black-faced, sound-absorbing insulation. AcoustaBoard has an abuse-resistant, nonwoven facing that is fully bonded to the insulation; delamination is not an issue. It is widely used to improve acoustics in theaters, sound studios and entertainment facilities—controlling reverberation time, reducing noise levels and eliminating echos—and is ideal for interiors that are meant to be dark. It is lightweight, easy to fabricate and install, and carries a Class A/Class I fire hazard classification of 25/50 for exposed applications.
By expanding 35-50 times it original volume, CertaSpray efficiently seals all voids and cracks which blocks air and sound from travelling through the wall.
