Where will a man hear a louder sound - at the node or at the antinode in case of a stationary wave?

Answer:

                The sound is heard due to variation in pressure, which is given by \[\Delta P=-Elasticity\times Strain\] At the antinodes, amplitude is maximum but strain is minimum. At the nodes, the amplitude is minimum but strain is maximum. So variation in pressure is maximum at the nodes. Hence a loud sound is heard at node not at antinode.
