  • Soundproofing a Classroom

    Good acoustics play an important role in the effectiveness of instructional spaces. Classrooms with excessive noise reverberation make it difficult for students to understand what is being taught. Children with learning disabilities have a far more difficult time paying attention to their teacher, which is neither good for the student or the rest of the class.

    Recently, the American Speech-Language-Hearing Association (ASHA) along with representatives form the acoustics industry issued the paper “Position Statement and Guidelines for Acoustics in Educational Settings.” Outlined in the paper are a number of 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.

    Soundproofing a Classroom with AlphaSorb Fabric Wrapped PanelsWhen 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.

    Using these guidelines when soundproofing a classroom will greatly increase the student’s ability to understand the instructor and create a better learning environment.

    Soundproofing a Classroom with Acoustical PanelsTo 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 Acoustic Ceiling tiles to the rear ceiling area will help with the projection of the instructors voice. Sonex ceiling tiles without backers are designed to be used as acoustic wall panels or ceiling tiles and are installed with a water base adhesive.
