Question

the intensity of reverberation is higher in a closed and empty house​

Answer 1

The reverberation time is larger for an empty hall than for a crowded hall because there are many sound absorbents present in a crowded room, whereas the sound is reacted back by the walls of an empty room. Therefore it persists for a longer time in an empty hall.

Or we can say

In a empty house there is nothing to absorb sound but everything for an echo, hence, Reverberation is greater !!
