    The reflection of sound may take place at curved surfaces also. This fact is made use of in the large halls to spread sound evenly throughout the hail. This is done by using sound boards, The speaker is located at the focus of the sound board and the concave reflecting sound boards are placed behind the speakers in a large hall. The sound board prevents the spreading out of the sound waves in various directions. It sends the sound waves from the speaker at its focus, by reflection towards the audience. This helps in making the speech readily audible even at a distance.
