Many people find the world of acoustical treatments to be confusing and overwhelming. Here on the Acoustical Solutions Sound Advice Blog, we will concentrate on presenting solutions to typical acoustical problems and discuss relevant topics on the subject.
The posts here will be related general sound and noise control topics like blocking sound, absorbing sound, or diffusing sound. We will also provide information on how acoustical materials can be used or applied to specific applications.
What are Acoustic Baffles?
Because we’ve recently introduced a new collection of acoustic baffles, we thought we would tell you a bit about what exactly an acoustic baffle is and how it works in acoustic treatment.
First though, have a look at the baffles in our new collection.
Acoustic Lanterns are innovative ceiling baffles designed for hotel lobbies, restaurants and other architecturally demanding environments where acoustic control must integrate with its surroundings.
The 1% Rule: A 1% opening will allow up to 50% of sound to pass through a wall, door, sound barrier, etc.
This rule comes into play most often when it comes to doors. Whether a regular door or a soundproof door, small openings almost always exist at the bottom, top and sides.
It is because of the 1% Rule that these openings around doors effectively cancel out any acoustic functionality.
For example, a 1/8″ opening around all four sides of an acoustic door(STC rating of 56) can significantly reduce the door’s STC rating (to as low as 21), which means the door is close to useless acoustically.
