When Animals AttackI once witnessed my best friend savaged near to death by a flock of rampant killer sheep.
It's a kill-or-be-killed world out there and poor Steve Irwin never made it back alive. Tell us your tales of survival.

@RLIf you're down at those low frequencies and have an amplifier you can plug a sound output into, why not use an astable multivibrator (http://en.wikipedia.org/wiki/Multivibrator).
It'd give you an on-off pulse through an LED at whatever frequency you wanted, then you just check the voltage across one of the LEDs is a safe level for your amplifier, then solder on a stereo jack and plug it in! They'd not be any good for ultrasound, but for 5-30Hz I can't see any huge problems.
Tell us if you see ghosts, or gain mind-control abilities!
*Oh, you're just looking to scare kids. Ah, well.
