In school our teacher sayd that certain sound HZ can cause fear, headache and brain stopping..
when I listened to these sounds I did have a headache..
or it could of been my mind
well anyway, human ears cant hear under 20-25hz but your body can sense it.. try it.
-edit- found some intresting stuff:
