Question

Sometimes it is easier to hear someone speaking in a full room than in an empty room. Explain how this could happen.

Answer 1

Solution:-

As we know;

An empty room tends to be much more reflective i.e,bouncing sounds from wall to wall to window

to ceiling to floor with very little absorption. as most furnished rooms would have many soft

absorbent surfaces in addition, like chairs and sofas and curtains and rugs, each of which

would either diffuse or absorb some of the sound, rather than reflecting it.

=> A good balance between reflective and absorbent surfaces makes for the best acoustics in a room.

or we can say a full room with someone is better as it help not let the sound waves die.
