Question

explain giving scientific reason

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

​

Answer 1

Answer:

In an empty house, there is no sound absorbers present such as furnitures, curtains etc. ... Hence, the intensity of reflections do not fade which would have faded if the room was not empty (has sound absorbers). Due to this the intensity of reverberation is higher in a closed and empty room.

Answer 2

Answer:

In an empty house, there is no sound absorbers present such as furnitures, curtains etc. Also, if the room is closed, the sound cannot escape from the room. Thus, the sound goes through multiple reflections from the rigid walls of a closed and empty room without the reflections of the sound being absorbed. Hence, the intensity of reflections do not fade which would have faded if the room was not empty (has sound absorbers). Due to this the intensity of reverberation is higher in a closed and empty room.
