Ocean Roar
Ocean Roar
What causes the ocean roar (waves) one may hear in a seashell? .
- A. Actually, there is no roar. The sound entering one ear is muffled, and we 'sense' that as a roar.
- B. The roar is due to the shell's cavity acting as an amplifier for blood pulsing in our veins.
- C. The roar is due to wind and vibrations randomly exciting the shell's resonant frequencies.
- D. I live in the Midwest and am not interested in oceans.
