Final answer:
Amplitude determines the energy of a sound wave, and louder sounds have more energy.
Step-by-step explanation:
In physics, the energy of a sound wave is determined by its amplitude. The amplitude corresponds to the loudness of the sound. Contrary to the statement, loud sounds carry more energy than quiet sounds. A sound wave with a larger amplitude (louder sound) has more energy because it displaces more air particles and transfers more energy to the surroundings.
