Paul Ogea: You would probably be better off using something like suspended ceiling
tiles. They are relatively cheap and are designed to absorb sound.
klosnoski: dynamat. worth a look
Tom Hoehler: Very well done. I'll bet your neighbors appreciated the noise reduction
too. I am going to try this, my Briggs&Stratton generator is one noisy
beast. The Honda inverter type generators are very quiet, but very
expensive. Thanks for posting.
John R: Now thats a quit generator
Mike Sullivan: Looks like some grow room build techniques going into that....Nice job
Bill Hier: What are the interior dimensions?
Rusty Rowe: Do you now the db difference? I'm thinking of doing something similar for
my food truck. I have the 12.5kW powermate and its loud as crap! hoping
that 18" muffler quiets it down.
Robert Trull: how many amps does that fan pull?
gtiplus: Thanks for the ideas
mystiksoldier: Brilliant. NASA could use you right about now.
strassercaster: should have designed it with the exhaust aiming away from the house .
strassercaster: why did you point it at your house and a window.I would put a flag like
Board on a pole about 2 feet away from the exhaust .Angle it at 45 degrees
away from the house.When i was a carpenter we just stood a sheet of
plywood up nailed too a 5 ft board ala kickstandand sheilded our side.
Sheild that exhaust aiming at your window.
2HeadedOgre: Despite the concerns that others have brought up, I am sure it works well
to have a weather proof place to store your generator when it is not in
use. Also, for how infrequently one needs a generator, the enclosure
probably suits the purpose fine. I am just curious, has your neighbor
complained that the engine exhaust is directed into their yard?
roknwoe: Your shelter looks great! Much thought went into it! I have learned it is
extremely difficult to quiet down these portable generators. The big
Eu6500i Honda runs about 53 decibels with no shelter, but costs $3600+.
Sometimes I wish I would have just spent the $3600+ instead of buying a
cheap Chinese generator for $800 (9000w unit) which runs about 76 decibels.
It is so noisy, you can't hang around it for more than 2 minutes before
you have to walk away due to the noise. You shelter is practical and
thrifty for its purpose. Hats off!
rich d: Real nice job!
My grandfather buried his muffler in a bed of rocks and sand just outside
of the generator shed. The only thing you could see was the exhaust pipe
going straigtht down into the dirt. The gases came back up out of the
ground via a bed of rocks/gravel. It was very quiet.
You can also heat water with the exhaust using a water heater for a muffler.
Wewaswampboy: Consider running the exh. tube above your house eve. It will reduce your
noise level. We did it in the military, Sound travels up up up, so you do
not hear it on the ground as bad. Exh. fumes go up with the noise.
walkertongdee: I'm thinking that that liner inside is amplifying the sound. You could try
something like acoustic tile that would help. Enjoyed the video!
David Chandler: line it with corrugated foam rubber. Like you use in a sound studio. It
absorbs alot of noise. Mattress pads work well , but the heat eventually
messes them up.
iam1inamil: dig a hole with an access ramp so you can pull it out to service it...also
run a drain pipe to let any surface/groundwater flow to lower
area.......the thing about inventions is,you need to have to humility to
take the better idea after a bunch of time/money,energy has been expended
on your project
bobsteroni777: Nice effort. Acoustically speaking, tho, the the idea of using thin metal
sheeting within the enclosure is ill-advised. What dampens sound is loosely
coupled (or not coupled at all) sheer mass. There is a product called
"loaded vinyl" or "mass-loaded vinyl" which is heavy > 1lb per sq ft. which
is used to reduce coupling of vibrations from a sound source to the
outside. Affixing the material loosely to the inside of your enclosure will
be much more effective in your results.
royalcreations: Thanks GS12. Its a attic vent from home depot.
royalcreations: The generator is tied down inside the shed with recoil is facing out.
Two-three pulls max to start. Not an a issue. Roy
Hardwarenutz: Great Shed!
pulmonq2: This is not "soundproof". The definition reads "preventing, or constructed
of material that prevents, the passage of sound." The generator could be
heard all the way inside the patio. You have what.. a layer of thin plastic
and a thin metallic layer? THat's not going to do anything, and you can
just hear that even with the housing closed it's loud. Please try again and
this time use some proper sound insulation. Don't be a noob.
Neal Neals: is that a pvc 90 on your exhaust pipe?
Camshaft Shaft: Looks great but need much more air flow and should be blowing on the motor
I would imagine on a hot day a hour of run time could over heat:/
Al Ruark: Hello royal, thanks for the update, Great job, Great video, My buddy and I
used most of your design, we haven't got to the muffler yet because of
Sandy but we were ready for her, my buddy did lose his power but is up and
running, what is the small black intake fan and where did you get it Thanks
NonyaBusiness!: Assuming the vast majority of exhaust is being vented out, you're only
generating heat from the little exhaust that's probably still trickling out
and the general heat from the engine running. I'd expect a fan (his is
rated at 900 cfm) to easily take care of the rest. I've built my own custom
shed and will post a video when everything is complete.
Michael P: Should have used sound-deadening composite panels on the interior of the
box instead of the faux stainless steel to deafen the engine noise. Get
them in the insulation dept of Lowes or Home Depot. Just don't get them wet.
OldRangeRat: Nice shelter -
rockshox911: That actually worked alot better than i thought it would. Although you need
something to add mass to the panels. Check out quick-roof peel and seel. It
is aluminum backed and comes in 6"x25' rolls. Add that to the inside shell
of your "shed" and a couple patches to the aluminum panels etc. If you
really get bored, you can also add some egg-crate foam and line the inside
of the box with it. Both together will reduced box flex/vibration and will
kill a large amount of noise.
LoganAddisMusic: I agree, something like MDF would greatly improve his current setup
Marty P.: Nice job. Have the same shed from Home Depot. Tried to run it during Sandy
with cut out exhaust in the back and only a cut out for intake air. Choked
itself out where I had to buy a new air filter. My bad...I did not use any
insulation concerned of high heat and fire or melting plastic shed. Do you
have a "parts and pieces list" that can be related to the visual and where
they can be purchased ? I am handy however need additional detail. Thanks
for posting this.
mydejavooo1: Wow.....no offense, but that's louder than my Schuck's 4000k genset with no
soundproofing at all. Even cheap rolls of insulation batting and heat
barrier would quiet that beast by a LOT. Check other videos where guys make
theirs almost silent. Nice layout though!! :)
Neil Gooler: Hi Royal, Nice Job on the enclosure. I wanted to inquire about the high
temp switches. They look like dryer high limits. Is that what they are I
wanted to find something like this also where did you get the temp read
silverbankruptcy: Your work and muffler reflect well on your mechanical abilities. I just
have difficulty understanding why the temps are 50 Degrees above the
ambient temperature. I think that part is that metal giving off heat in the
box, Not sure that the sound/heat tradeoff is worth it. I would change Left
Side Grille to a Louvered A/C Grille that you can manually open. A little
more sound yes, but I think Temps would Drop 10 Degrees or more. my temps
are running 12 Degrees ambient see my video v=3GE_qqRMWN8
studiosGS12: Great Work! I have the same fan and was wondering where you bought the
outside vent cover from. Looks like you cut it open from your previous
version and installed a temp gauge also. Pretty sweet!
Tony Arellano: well done!
Tom C: Im curious about your emergency off switch set up. Whats it tied into, and
can you also start the gen from here? Thanks
Jared Greenberg: Great Job
hot2warm: Excellent set-up! I'm still searching for an appropriate generator and have
some ideas on how to make an enclosure or purchase a utility box such as
the one you used. Is your generator a recoil start or electric start. If
it's recoil, how difficult is it to start with the enclosure?
Doug Listman: Can you explain how you connected the exhaust system to the exchause out
put on your generator? How do you do this so that it doesn't fall off and
doesn't heat up too much? What is the connection?
Sherman Shewmaker: Did you provide a decibel level for BEFORE and AFTER? Didn't see one.
Bassem Rashidi: check out GeneratorDepot.us for the best generators and the best deals.
thats where i bought from after Sandy. I recommend the GG6000P or GG10020
Al G pa: Oh hell yea if could live with that don't listen to the know I alls great
job it's yours be proud
James Starks: Just a thought. A plastic bucket covering the exhaust fan on the inside (On
top of the generator) with maybe a 2" all around larger size than the fan
(to minimize airflow loss) would work like a muffler baffle, and would
knock down the sound coming from the exhaust fan.The sound waves inside the
box have a straight shot out without the baffle.
wilatemodel: How is this "Soundproof"?...
Joe Sommers: Reminds me of a 30 piece hammer
