Thread: What is the best way to overcome that loud hiss from pneumatics and servo noise

Tweet

Anyone got any pointers, i know i can cover it up with blaring audio , but i just wanted to be open minded and see other peoples ideas too

I know you already said, But An even louder soundtrack seems to be the best bet for me.

Servo noise can be dampened with foam and a hard plastic or metal cover.
Pneumatics noise can be dampened with silencers or mufflers or even a piece of tubing. It the hiss is coming from a cylinder you can route the exhausted air away from the location with a tube or a hose.

Yep, That's the best answer I think....I got a couple silencers in the last monsterguts kit I got but haven't had a chance to try it out yet.....I used loud audio last year as that seems to be what most haunted houses I've been in did....If the silencers make a big difference then I'll buy more for the rest of the system....ZR

I've heard of some where they route the exhaust air to another part of the haunt and use it as an ankle tickler or just a simple scare. The timing for that could be tricky though.

You could always run the exhaust lines to a pile of rubber snakes,........Give it that realism..... & hide the sound to an effect ! Maybe even a few ankle whippers with the snakes.

Thanks all, im really liking these ideas, i believe the kits from monster guts come with silencers... but i do like the snake idea, or the ankle tickler.. all really good ideas, haha ill have to try them all

What I found worked best for me was to route the exhaust through a short piece of tubing into a foam box that was stuffed with a dishcloth and that had a few small holes in it to make sure it wasn't air tight. I also reduced the air pressure as far as I could. The result was silent. All if the different types of silencers I tried reduced the volume of sound but they still made a very noticeable high pitched hiss.

For servos, I turned up the sound. My skulls didn't have much space for insulation and what I put in didn't seem to help that well. I heard something on the radio yesterday while flipping channels about a foam glue that absorbs sound. I don't know anything else about it.

i figured out what i want to do now, i aprecciate you looking for that link... but that stuff looks kinda pricey. I think i am going to run a line down to a cannon with a fog resovoir, im setting up a pirate theme this year too, i found a really neat flag that i would like to share with you all too Pirate Flags 3x5ft (ALL) | Pirate Morale Flag | FlagsImporter.com

I remember Dave the Dead over on HauntForum attaching a predator game call to the exhaust of a pneumatic prop. It created a scream that was creepy as hell.
