Earth hum explained

For years people have reported a strange hum in many places around the world. One famous place is Taos New Mexico en.wikipedia.org.... The hum is thought to be connected to ELF submarine communications, HAARP, generators for underground military complexes, to tinnitus or tectonic activity.

A relatively new theory is that the sound is produced by ocean waves.

The hum is a low rumble continually present in the ground even when there are no earthquakes happening, but is detectable only by very sensitive seismometers. Its frequency is near 10 millihertz, below the range of human hearing.

Webb has applied old work on ocean waves to predict what sort of background noise would be made by waves moving over the shallow ocean floor. He found his prediction closely matched the spectrum of the Earth's hum.

He says the hum is caused by the combination of two waves of the same frequency travelling in opposite directions. The waves alternately cancel out and amplify each other so that the sea surface goes from wavy to flat to wavy. This creates a standing wave that "goes thump, thump, thump on the ocean floor at twice the frequency of the waves you started off with, driving the hum", says Webb.

I'm not sure if this is the same hum because the article doesn't mention Taos specifically, but it seems like it's the same noise. Of course this doesnt explain the hum on Mars...

Thanks thats an intersting read,

I wonder if theres any sound bites anywhere would be interesting to hear,
