Question

Reverberation of sound is due to

• A. multiple refractions
• B. multiple reflections
• C. multiple diffractions
• D. multiple polarization

Answer 1

The correct option is B multiple reflections

Reverberation is the phenomenon of persistence of sound after it is stopped by surfaces such as furniture, people, walls, etc. within a closed space, causing multiple reflections. These reflections build up with each reflection and persist for a finite time and then decay gradually as they are slowly absorbed by the objects in the space enclosed.
