Answer 2

metal sheet will reflect your sound more effectively


Reason:
Soundwaves are a lower, light is higher. All energywaves will prefer a hard flat surface to reflect without losing energy, anything less will absorb energy and cause scatter. Hardsurfaces are best because sound is related to pressure. Elasticity is best for such hardsurfaces.
