My p1s is slightly louder than my old MK3S+. I have to turn down the aux fan and chamber fan, otherwise it would be way too loud. I wish there are better part cooling fans available, so it could be more quiet.
But in order to print fast you have to have the part cooling at high levels (at least for PLA/PETG) or the door open. Then the chamber fan might also be disabled. But still load.
For me only printing ABS/ASA is somehow not that noisy, when I disbaled chamber fan, part cooler and fan at the print head. Anything else has to run during the night when I am not near the room.
The champer fan is 24V and in some videos people showed that if you install a slower fan then the software will still keep the high standard rpm as 100% (about 4800rpm), and the new fan will then only work at 40% relative to the old. At some point the software may also recognice a fan as not working. The software is not open source and setting modifyable like e.g. on Klipper or Prusa. I think the next printer will be a more open device even I like the simplicity of printing with the bambu P1s. But there are some big cons.
Mine sits on 2 inches of rubber as well as a paving stone which helps a lot.
I got my P1 last night, installed on the floor and printed little boat thing. And it was loud.
Someone mentioned sound cancelling in a firmware update on Reddit, but I couldn’t find any additional information on it.
I think a sound and vibrational analysis is in order. I couldn’t find any information from Bambu about the sound generated by the P1S - decibels, frequency that sort of thing. I’m hoping to use this information to choose the right insulation material to build a box for it.
I’ll post back if I do manage to do it in the meantime if somebody does do it. Please let us know.
So, I recorded the sound outputed from my P1S from bed levelling to print completion at default speed. the audio sample was a total of 30 minutes.
Here are some plots

Summary for my setup:
Significant power is concentrated in the Low Frequencies (0-500 Hz), indicating bass-heavy or deep sounds - fans, toolhead drive motor and belt.
There is a sharp High-Frequency Peak (~15,000 Hz) which almost certainly from the fast toolhead motion and breaking.
I post about the materials i choose once i get to it. and them there is vibration!
(Ho do i add images to posts? is it possible?)
Copy and paste.
Blablablabla.
Once you become a basic user you will be able to do all of these extra features.
I’m confused.
P1S is pretty noisy… at least in comparison with A1 Mini, are not just the fans, the rods system that transfer the noise in the printer box and that is making the biggest noise. Mine is new just 2 days old, so please don’t think abouse cleaning the rods or something similar, the noise at 1m is almost 80db that’s huge, at 50% speed the noise is lower but still very noisy. If with A1 mini was possible to sleep a side, with P1S no way even to watch a movie with the headphones on my ears. Other cons I don’t have until now, is nice, fast, print great, but very noisy!
I find it fairly quiet - but it certainly isn’t silent. I doubt it would disturb neighbors.
Something is wrong with your machine if it is that loud.
A quick search of 80dB sound examples, I get
Busy Road with heavy traffic
Power Lawn Mower
Window AC Unit
Car Wash
Ringing Telephone
Loud Alarm Clock
Yep, this is what I have for my setup. Cheap, heavy and stable.
@fane Have you inspected the machine fully so the if the noise is coming from a specific area?
It should not be that loud 80db would require earplugs ( for industry wide jobs)
Maybe start by going to bambu studio or handdy app and begin with calibration and noise canceling it should run around 27 minutes to calibrate then if it continues you may have a bigger issue at hand if it reduced know slow print to silent mode and or create a new profile slowing print speed manually in the speed tab depending on your needs. Another is adding rubber feet to the( p1s should have included) printer .
It kinda depends on a few things, but in general, yes there will be a significant difference to the A1 in many scenarios.
For example, if you are printing ABS/ASA, you probably wouldn’t think the P1S very noisy at all. But for PLA/TPU, its downright loud in many prints. The chamber fan, hot-end fan, and aux fan create quite the symphony. I didn’t even mention the board fan which can also add in. But if you modify the fan settings a little, you can definitely get a lower sound level. Like turning off the aux fan or keeping it under 50% can really help with sound. Just make sure you are not create new problems.
Another thing to check is the stepper tuning. If you have updated the firmware or reset the printer, maybe a re-running of the stepper tuning could help with stepper noise. No guarantees on this last one, because I would imagine it would remember the tuning, but it worth re-running, IMO.
Half a meter from my X1C, printing with door open, top off, all fans at 100%, the highest reading I can find on any side is 60dB. Replace the top, close the door, and the maximum drops to 57dB, or half as loud.
80dB at 1 meter would be 100 times louder than my X1C is at half the distance. I think you have a major problem with your P1S.
Major problem like what? This was doing from the first time i turned on, printing amazing, the noise amazing too… like you guys said heavy traffic 
I don’t know how you measured yours but i used first my iphone and second a special tool that i use to measure the sound level in clubs. The noise is between 70-78 sometimes 80db specially when the extruder moving in x or y axes. I really can’t use at night in apartment, i think i will put on sell and take out my old A1 mini…
Btw, i print only PLA bambu lab filament.
It’s extremely loud. I live in an old apartment and the noise is unreal. Louder than someone watching TV and in a way that feels like water boarding. The belt harmonics and the shaking are about the volume of a trombone shaking my whole apartment on the calibration at startup. There’s no way your neighbors won’t be disturbed, mine is on concrete and vibration feet and foam and other things stacked doesn’t matter. If you can sleep with a diesel generator or a vacuum banging furniture you should be fine. If you don’t have a sound proof basement it’s all you can hear. I have turned it to roughly 10% speed and that’s fine during the day when neighbors are loud but at night there’s nothing that can be done to allow anyone nearby to sleep, pure torture.
Yep, the P1S is extremely loud. I probably would not have bought it if I had known. I also have an A1, and the A1 is nearly silent in comparison.
I ultimately spent many hours lining the inside with a dense sound damping material (used in automobile sound systems) and a layer of 3mm felt on top of that. It reduced the noise to tolerable, but it’s still louder than my A1.
The fan noise, thats whatever. Its more of a you problem that sounds doesn’t travel well into neighboring apartments.
I know this is old but the P2s is even worse apparently. Third floor apartment and I feel like crap running the thing. right now it’s on it’s stock super squishy feet, with concrete slab and rubber paver on a table, I can hear the vibrations traveling through the walls…
A1 mini is dead silent… kinda wish I woulda bought an A1 I didn’t even think about the noise level.
It’s mostly the big long travels across the print when x and y motors are moving together, and any retraction. This kinda blows I love the machine but there is no way this can work.
