Classroom acoustics

In a classroom, reverberation affects speech intelligibility, especially at the rear. Even ceiling absorption and treatment on upper walls are the priority.

Priorities

  1. Set the source and listening area symmetrically.
  2. Evaluate decay by frequency band, not only one number.
  3. Add treatment in stages and save variants.

What to avoid

Do not buy a complete package from one calculator result. Start with a baseline, then measure and adjust.

Example

Example: a 4.2 × 3.4 × 2.6 m room with hard walls and partial panel coverage. Change one parameter at a time and compare saved variants.

Limitations

The result is a first-order model. Real reflections depend on geometry, furniture, gaps, mounting and the positions of the source and microphone.

FAQ

Does this replace a measurement?

No. It helps plan an initial variant and budget, but final decisions should be verified with an impulse-response measurement.

Are more panels always better?

No. One-sided absorption can leave bass problems unresolved and make the upper range too dry.

Where is data stored?
