Good acoustics play an important role in the effectiveness of instructional spaces. Classrooms with excessive noise reverberation make it difficult for students to understand the lessons. Children with learning disabilities have a far more difficult time paying attention to their teacher. This is neither good for the student or the rest of the class. Soundproofing a classroom can enhance the learning experience.
Recently, the American Speech-Language-Hearing Association (ASHA) along with representatives from the acoustics industry issued the paper “Position Statement and Guidelines for Acoustics in Educational Settings.” Outlined in the paper are several suggested guidelines concerning maximum ambient background noise. The paper suggested a Reverberation Time (RT 60) of .5 seconds (in the speech intelligibility range), in the classroom.
When Soundproofing a Classroom, Here are some suggestions concerning acoustical treatment location:
- Install absorption materials on the rear wall opposite the instructor. Don’t cover them with hard reflective posters or surfaces.
- Add acoustical treatment to the rear ceiling area, keeping the front ceiling to midway reflective to help with projection of the instructor’s voice.
- If required to reach the suggested reverberation time of .5 seconds, add additional acoustic treatment to the upper side walls or the walls opposite windows.
To create this better learning environment, we suggest using our AlphaSorb® Fabric Wrapped Wall Panels. Installing the panels on the rear wall opposite the instructor will cut down on the excessive noise reverberation and echoing. The panels will answer your acoustical and aesthetic needs with their strong sound absorbing performance, durability and elegant appearance.
Adding Sonex® Contour Ceiling Tiles to the rear ceiling area will help with the projection of the instructors voice. Sonex® Contour Ceiling Tiles without backers are designed to be used as acoustic wall panels or ceiling tiles and are installed with a water base adhesive.
