I got you OP
This is the hard hitting humor I need in my life
I see you saved denoise until composting like a True Chad.
Well, the way a suppressor works is by providing space for rapidly expanding hot gasses to slow down and spread out without allowing them (and the sound waves they will propagate) out. It’s usually just a hollow metal tube with baffles, possibly wire mesh or rubber wipes as well to slow the gasses further.
In a blender, the thing that makes noise isn’t a bunch of hot expanding gas, it’s a motor; and it’s not a sudden impulse that dissipates like a gunshot but a continual, droning noise at high volume. Silencing a blender, while in theory the same problem, would require a very different solution in practice (built-in dampening/sound insulating foam in the base, perhaps?)
And blenders are designed to let heat from that motor out. If you trap it in, it will fuck up the coils on the motor.
Perhaps a heat sink on the outside that has tubes extending out of the sound proofing and connecting to the motor.
Not to mention that a “suppressed” shot is actually still pretty loud, but people believe what they see in movies
Completely depends on what weapon we are talking about. Check out a Ruger Mk 4.
We also have the technology to have silent vacuum cleaners. The only reason they are loud now is because people think louder means more powerful.
That’s just because sound doesn’t travel in a vacuum.
Brilliant! I’ll put my blender in my vacuum chamber!
It’s also worth mentioning that a gun with silencer is still louder than your typical blender. Silencers are for hearing protection for the shooter, not for stealth. Blenders are not loud enough to require hearing protection.
(There are some exceptions, some guns with silencers really are quiet enough to be stealthy. But those are some highly specialized and quite weak guns.)
Are the quiet ones subsonic 22 pistols? Do they make the sound from video games?
.22 can be actually truly ‘silenced’, yes.
But, most video games and movies use … inventive sound engineering, basically.
An actually silenced .22 pistol basically just sounds like a ‘click’ or ‘thwick’ type of noise.
There’s no ‘psssshew’ kind of noise.
You get that kind of noise with a more powerful, suppressed round, but its… loud.
Like the uh, the awesome silenced shotgun noise used in No Country for Old Men?
Pretty much totally made up.
It is technically possible to supress a shotgun (that movie spurred people to figure out how, lol) but it doesn’t sound like the movie at all.
EDIT

There, there’s a vid of a .22 pistol firing without and with a supressor.
Its genuienly difficult to capture what gunshots truly sound like in person, on video, partially because the environment the gun is being fired in significantly changes the sound, and also because unsuppressed shots are just so loud that they basically overwhelm standard microphones that tend to be optimized around capturing human speech.
Dude, my blender is much louder than any EV with 800+ hp. I know, size of the motor, but I believe they just want to make us deaf.
I’ve heard cars and trains with electric motors more quiet than a blender. There surely is a way, it might just not be cheap.
Their motors are enormous and designed for low speed, high torque; as a result they’re able to spin much slower than the motor on a blender, making them far quieter. A blender’s entire purpose depends on getting the most agitation into a material in the shortest amount of time - this is by definition a noisy process.
Ok, what about a slow, powerful motor with a couple gears between it and the blades. And everything is well machined and lubricated.
The reason blenders connect the blades directly to the motor shaft isn’t just cost savings — high-speed gear reducers are very large and surprisingly complicated while at the same time vastly increasing the torque required (and transferring all that shock absorption of operation from the nice robust rotor to the poor, precision machined gearbox). I’m pretty sure that yes technically you could use a setup like that to greatly reduce motor noise however: you’re just shifting the high speed portion from the motor to the gearbox, and you will still would need to address the primary source of noise generated by a blender (the blades themselves interacting at absurdly high speed with the food).
It’s an interesting idea though, and at the very least the great horking gearbox would contribute to acoustic dampening through sheer mass alone…
I’d imagine a double container, and the internal container is where the “blending” occurs, and this whole second container is vacuum pressurized inside the first container, with dampeners, rubbers, foam rubber. If we don’t account for size, or care for it, I’d wager that a silenced blender would cost upwards of €6k - and I’m just calculating the price for the parts, with some sandbagging. With all other costs that come with a new product, and a greedy corpo lust for profit, they’d probably sell this at €12k retail
Hmm, double container… oh, I bet that’s why the commercial blenders you see at cafes and smoothie shops have those folding covers!
Yeah I was going to look for and share, that’s literally the silencer for a blender the OP is looking for. Only places that are cheaper and don’t have the budget or concern to care about the noise go without.
Build it! Sell it to idiots! Make that bag!
The main thing that makes noise in a blender is all the shit inside of it crashing around and being obliterated.
That’ll get much louder than just running the motor with nothing in the blender.
So even if you could somehow lessen the actual noise of the motor (sound dampening foam / chambers built around the motor enclosure?)…
… you still have all the noise of the shit being blended.
Asking how to silence that is like asking how to silence a car crash.
This is already solved and you can see it at a booster Juice or whatever smoothy place is near you. There is a plastic cover you fold down over it to reduce noise. It is even marketed as such.

$1500 for a blender?
Uh… no?
Is there a consumer grade version of this, that maybe costs 1/10th that much?
Otherwise, earplugs, or an earprotection headset, are quite a lot cheaper.
Its insane how much that lil dinky plastic cover actually does to actually make it quieter too I know theres probably rubber grommits and whatnot at contact points but the fact a clear hard plastic cover makes something that sounds like an angry maloperated pear wiggling machine to almost the smooth sounds of power from an advancing Rolls Royce always surprised me.
In a blender, the thing that makes noise isn’t a bunch of hot expanding gas, it’s a motor
It’s not actually the motor that makes the majority of the noise, it’s typically what’s attached to the arbor of the motor and the housing of the motor. Electric motors may hum a bit depending on their size and rpm, but they’re not very noisy machines.
Blenders are noisy because they’re usually poorly housed in cheap plastic that rattles, the machining from the arbor to the attachment that spins the blade is often also loosely geared plastic, and you’re spinning metal blades to slam into things at a high rpm.
Probably the same issue as with the vacuum cleaners. They could (and did) build much more quiet versions. I’ve seen and heard one on TV once. But they simply died in the market, because they did not sound powerful enough.
Could they try again maybe?
I feel the same about coffee grinders.
At that the coffee grinder rewards instantly with tantalizing freshly grinded coffee aroma.
Btw, using worm shafts to somewhat quietly crush and press the beans in hot water?
Some of the nicer burr grinders are significantly quieter. Still not close to silent, but much less likely to disturb someone in another room.
I had a Bosch SilentMixx mixer before. It’s not quiet, but way less loud than a regular blender.
I put my blender on a kitchen towel when I use it. It doesn’t make the motor itself quieter, but it doesn’t reverberate on the countertop which causes that low pitched rumble when blending.
Suppressed guns are still VERY LOUD
Am I the only one that owns earplugs?
Yes. Can I borrow them sometime?
Then I won’t be able to use my blender…or mixer… :(
Brushless motors
Yes! There are quieter blenders out there. Regular blenders use universal motors which are cheap and powerful but also very loud. Think of vacuum cleaners, where the cheap ones are loud and the expensive ones are quite a bit quieter, e.g., Dyson, Miele. Brushless DC motors are powerful and simple but require complicated and expensive electronics to control them.
Blendtec and Vitamix are the best known blenders that use brushless DC motors. Nowadays there are lots of others. Vitamix makes a higher end version of their blender that provides a sound deadening enclosure for the whole thing, complete with thick rubber gaskets. It’s pretty effective and costs about 2000.

Even with a brushless motor, a standard Vitamix (e.g. a 5200) is definitely not quiet! It doesn’t help that the ice (or other hard ingredient) hitting the side of the container is loud in and of itself.
It’s a shame the enclosure apparently adds over $1500 to the cost.
You’ll see a similar device at Most Starbucks’s. It’s what they use to make the Frappuccino.
You had me until the $2000. Yeah I’ll just put my blender on a kitchen towel, thanks.
Being Swedish I automatically read 2000 as ~$200 and went all “that’s not so bad!”
Turns out it was pretty bad. I’m not professional enough to warrant such an expense.
They cost so much that consumers refuse to buy them. If you look hard enough though you can find them. Try looking for commercial kitchen equipment.
Got the autism huh?

Pro-tip: When crushing a batch of dried ghost-peppers in a blender, make sure you cover the top with plastic cling wrap before you put the lid on.
Don’t ask me how I know…
If anyone can do it, Dyson can.
