Sound is louder when a vibrating source is held to a sounding board because more surface is forced to vibrate, pushing more air. True or False?

Answer: True

Explanation:

A sounding board has the property of receiving a sound wave and transforming it into vibration of the air molecules inside it; resulting in amplification or modulation of sound.

In other words, when the sound waves pass through a sounding board, the resulting sound is louder (amplified) because its surface is forced to vibrate by the air molecules present within the mentioned sounding board.
