The Noise of the Sea Exceeds that of Thoughts

We definitely hear it at our house, but we have found that the sound levels have absolutely nothing to do with the size of the waves!

The opposite at my house, sometimes we feel the rumble of big waves through the floor. When the thunder and waves meld together (kinda like when Jupiter aligns with Mars, and, you know, and peace will guide the planet or somesuch), it's like the purest white noise ever. Like the Japan White of white noise.

When I first wake up, I always seem to hear anything but the surf. Is that the wind? Thunder? A train? There are no trains here, the ocean maybe?
