Drain sanity while looking at something?

[SonOfLiberty796]

I think the insanity areas are only triggered when your Insanity is low (25 or less I think). Thats how I've seem them work so far, you get a random sound played back at you.

I've tried placing multiple ones close to eachother (5 seconds apart) but the 2nd or 3rd one won't trigger.

Ohhh...Well isnt there another way to do what I mentioned without insanity areas?
