Which makes more noise?

Unread postAuthor: warhead052 » Sat Apr 02, 2011 11:37 am

Which makes more noise? A solenoid on a sprinkler valve, or a sprinkler valve with the solenoid holes filled?

Isn't the noise a factor of how much air is left and at which compression factor after the projectile left the barrel (except faster than sound oeuf-corse).

I'm confused :?

If you are piloting with a blow gun or ball valve, the soland will have zero effect on the noise.

Blowgun, but some how the solenoid that came with the sprinkler valve is making an airhorn type noise...

that's because its not piloting fast enough. Try switching to a ball valve or modifying the blowgun to dump air faster, and the honking will go away

I would vote for solenoid valve feeding a locomotive horn, but that wasn't an option. :D

JDP, I want noise. Like, ALOT. And Tech, I like that idea, just that train horns in my neighborhood might not go down too well....

You will get zero noise with a diaphragm valve or a solenoid :wink:
If you want noise, make a big pneumatic piston valve or a combustion.

If its honking right now, its not efficient. If you want noise, build a cannon with a big piston valve, and a short barrel. if you want LOTS of noise, check out Starman's series of noisemaker cannons.

Basically a combustion with a burst disc, and no barrel. Extremely loud.

by doing what I described in my earlier post. change to a quicker venting pilot valve.. that will eliminate the honking and make it fire more efficiently.

For real fun, use train horns on a small island. No trains.. :D

@ Warhead, add a trumpet shaped barrel for better effeciency at making sound.
