Question
Explain by giving a scientific reason.
The intensity of reverberation is higher in a closed and empty house.
Solution
In an empty house, there are no sound absorbers present such as furniture, curtains etc. Also, if the room is closed, the sound cannot escape 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 does 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.
