Explanation of Solution

Introduction:

Reverberation in acoustics is the persistence of sound for long time after the sound is produced. It is the collection of reflected sounds from nearby surfaces.

In order to reduce reverberation the sound waves need to be absorbed as they touch the surface. Some of the methods to reduce reverberations are,

  1. Cover the floor with thick carpets.
  2. Use heavy curtains and sheets and cover the windows.
  3. Use fibreboard which is good sound absorber.
  4. Hang heavy drapes from ceiling.
  5. Fill the classroom with maximum number of desk and benches.

Conclusion:

Thus, reverberations in a classroom can be reduced.
