Question

which of the following would be most effective in reducing noise pollution in a school gymnasium during sports events? removing court floor padding installing acoustic wall panels using large metal bleachers adding more lighting fixtures

Explanation:

To reduce noise pollution, we need methods that absorb or dampen sound. Removing court floor padding would likely increase noise (as padding absorbs impact noise). Large metal bleachers can reflect sound, increasing noise. Lighting fixtures have no effect on sound. Acoustic wall panels are designed to absorb sound, so installing them would be effective in reducing noise in the gymnasium.

Answer:

B. installing acoustic wall panels
