The intensity of reverberation is higher in a closed and empty house.

Question

Explain giving scientific reasons:

The intensity of reverberation is higher in a closed and empty house.

Answer 1

• Reverberation occurs due to multiple reflections of sound. 
• The furniture in the house acts as a sound-absorbing material. 
• So if the house is closed and empty, a reflection of sound will be maximum and hence, intensity of reverberation is higher.
