Answer 2

Answer:

1. When a man sings in a round room, he will be heard loudest when he is in the center of the room.
2. This is because the sound waves bounce off the walls and converge in the center of the room, causing constructive interference and increasing the amplitude of the sound waves.
3. When sound waves bounce off a surface, they experience a phenomenon called reverberation, causing the sound waves to bounce off the walls of the room many times.
4. This delays the arrival time of sound waves and can cause distortion, echoes, and other acoustic anomalies.
5. However, in the center of a circular room, sound waves are reflected in such a way that they converge in the center of the room, resulting in an amplified sound wave of greater amplitude.
6. This is called the "center of symmetry effect".
7. So if a man wants to hear himself sing loudest in a round room, he must stand in the middle of the room.
