Tim Kepler: Sand filled mufflers are really good and simple to make.
muskongasbay: "precise as a pensioners' erection"..... LOL in Corpus Christi, Texas!
Llathrum Marine Mechanic: I am looking for somethig to quiet my briggs engines down. I do not expect 100% quiet but I would prefer 80% total noise reduction. If I can figure up a method to make something I will post it.
Tyee Cambrón: wow did anyone try this?
I need something for my 49cc pocket bike. Just so I don't need to wear hearing protection. Also I need to sneak by the pp station here or should i say the oinker farm on the backstreets, I dont want to ride on the main road and the problem is there is a freeway and only 2 bridge crossings.
allthings possible: I want my motors to be louder I like to kiss off the naibors
stubbenmonkey: i really like that i used to run a little honda generator to power lights in the shipon that would of made it a bit more bearable working
Felton Rolle: Love it!
dtvgmedia: I was thinking the same. Also it seems to me that the rubber hose may be absorbing some of the pressure waves along its length.
A length of metal tube to absorb the heat, for motors than run longer and get hoter like a lawn mower; and given a long length of rubber hose, one might not even need the soup can. Instead just drill many holes with good spacing between them to further release pressure waves over time, like an air leak versus a tire explosion, with each firing of the engine.
Gatewayuser200: I think it will. Eventually
twocvbloke: I wouldn't mind trying something like this with my chinese SV150 mower engine, it's quite loud when it gets going at full tilt, but I think the exhaust pipe would get too hot for a bit of hosepipe to withstand, though if I pulled the exhaust guard off, I could probably just attach a can directly to the pipe sticking out of the "silencer" that doesn't really silence it... :)
Steven Hanglands: Isn't it strange that the people that have uploaded (contributed) the least are those that are the most critical of others work? If you have uploaded nothing, you shouldn't be able to comment on the work of others is my view. However... great video. The issue of noise is something I want to look at over the next year. I have found insulated exhaust hose, and want to try a partially passive/partially active exhaust scavenging system so I can run my engines in the garage. Thanks for the upload.
Yard Sale Dale: Well, most heavy baffler mufflers and silencers do cost some power, but how much power off a 5hp engine do you need to pump tires?
Yard Sale Dale: You can buy a can of soup broth, and it will drain out even a small hole.
Eric Williams: Thts a pretty cool idea
tendertears2001: I think your on to something there! I'll have to give it a try, you got my curiosity up! maybe use some metal flex hose or something. Sometimes simplicity is the way to go! awesome job
pupleon: Well said steam!!!!!!!!
