    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.
