Beautiful, DEEP, harmonic TONE, like a space chime, heard near Kaua'i Isl. Hawaii

YES. So beautiful, powerful, and loud, echoing from somewhere offshore, way past the reefs...east side of Kaua'i shoreline. BOTH, my wife and i, HEARD the same loud CHIME TONE, deeper in HZ frequency, almost 528hz? but so beautiful, no we don't do "pot" or any drugs. my wife is a med pro, I am a long time GLP'r...and nocturnal scientist. stars are always amazing here, ocean and moon always romantic, but this event,....WAS DIFFERENT. it sounded cosmic, but also in a way, GROUNDED. hard to describe, almost like a "signal", or a earth change, OR A SPACE CHIMING SOUND, SENT FROM SO FAR FAR, AWAY. "hey Dorothy, did you hear that? and i got a double nod, and my wife said, "oh yah, that was nice, where did it come from"? i was a little groggy, but replied, way off shore, or from SPACE. oh my....i will never forget how beautiful it sounded. with a slight echo...i am 48 yrs old, excellent perception skills, 20/15 and good hearing. it was @ 3am Honolulu time, on the 26th SEPTEMBER. 2012. hmmmmm... .. that date really made me think harder @ Nib's position, and or other space weather...magnetism...etc... any one else hearing a low tone chime or chiming echo, at night, near the ocean>? I welcome replies, but won't be on here too long...ALOHAAAAAAA~~~~ from HAWAII, better known as "ancient LEMURIA".
