Question

In an empty room why is it that a tone sounds louder than in the room having things like furniture etc.

Short Note

Solution

When a room has furniture reverberation time can be suitably decreased since furniture has a large absorption coefficient of sound. So a tone sounds with lesser amplitude and intensity. Whereas in an empty room, reverberation time will be more than a room having things like furniture.
