Tested this on my wife: terrible, disgusting sound. Tested on my youngest daughter: Mmmmmm...cool sound. Conclusion: not for 50+. Story as follows. Another civilization has a spaceship hanging around our planet. It's very large. about half a mile long, but you cannot see it other than with astronomer's instrument as it is too far from us at the moment. Space specialists have heard these signals before and they believe the aliens do some kind of surveillance, making recognition maps and landing places. They are cautious because they know we are aggressive species who have thousands of nuclear bombs.
