Reddit reviews Diversitech MP4-E E.V.A. Anti-Vibration Pad, 4" x 4" x 7/8" Pack of 4

your wife is farting

j/k

probably a plumbing thing (vent pipe moving in the wind? water hammer situation?) . do you share a wall with anyone? is your bed on wood floors or carpet?

if your bed touches the wall, move it out. perhaps buy some rubber isolators for the feet:

Is it the raw seek noise of the drives that is annoying, or the seek noise amplified by the cabinet the NAS is sitting in?

I used to have a TiVo on top of an armoire in the bedroom that echoed through the wood.. one of those relatively cheap floor mats for fatigue (foam mats that interlock) solved the problem for me entirely.. You could still hear the seek in a silent room, but not with the TV on. I now have a similar problem with 3d printers upstairs from my bedroom.. these work wonderfully to isolate the vibrations away from the cabinet and keep the sound at bay: Diversitech MP4-E E.V.A.

I use these in my apartment: https://www.amazon.com/Diversitech-MP4-V-Anti-Vibration-Pack/dp/B00BVEMLR4/

seems to work for my angry downstairs neighbor.

As others said, vibration is the real issue.I made a platform with these: https://www.amazon.com/Diversitech-MP4-V-Anti-Vibration-Pack/dp/B00BVEMLR4 and some insulating panel from home depot and helped quite a lot with the vibration coming from my kickr.

edit: inflating -> insulating

Well it's not quiet to be honest but you'll have a hard time dampening the noise no matter how you go about it, I do recommend getting vibration dampening cube thingies (like this or maybe this) to put under your rig just so the noise won't travel into the floor which will make it exponentially louder. Those anti vibration things also help keep the vibration in the rig rather than dispersing it into your surrounding area.

As for structural integrity, I've had no issues. I got a tube of threadlocker in case the screws would vibrate loose but I haven't put it on yet and they are still as tight as the day I put them in so I wouldn't worry too much.

Try using some of these. Diversitech MP4-E E.V.A. Anti-Vibration Pad, 4" x 4" x 7/8" Pack of 4 https://www.amazon.com/dp/B00BVEMLR4/ref=cm_sw_r_cp_api_S8XfAbH5554VM
Put one under each corner of the furnace where it sits on the trusses. You might need a total of six depending on how the AC coil is mounted.

Don't forget some sorbothane blocks to set it on. They reduce vibration transmitted to and through the floor by an amazing amount.

These work better than a mat. I just put them under main contact points of my trainer.

I bought some of these off Amazon https://www.amazon.com/gp/product/B00BVEMLR4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I cut them into four smaller 2"x2" squares and printed some feet for the bottom of the printer to hold them in place. My printer already sits on a solid 2" thick wood base but this helped cut the noise and noticeable vibrations transmitted through my enclosure.

4" x 4" x 7/8" Anti-Vibration pads, Qty 4 in total

Helping a friend this weekend who has a Synology NAS Rackstation, approx size is 2U high, by 22" x 24"

For now, she will be placing it on top of an old, heavy wooden microwave cart (on the top).

It's a solid wood unit; but I wonder if adding the above 4"x4" anti-vibration pads placed in each corner would help the vibration/noise

She might be doing a small server rack; but that is long time away. /thanks for reading

I bought these anti vibration pads from Amazon.

I put them under each clever if the base. THEY ARE AMAZING. I can sometimes not even tell it's printing. I often find myself now checking to see if it's still for some reason. Before you could hear the vibrations through the walls in other rooms.

For the $10 they cost I would recommend them to everyone.

Probably something like this

Anything rubber would at the very least dampen the vibrations. Possibly even like a cork drink coaster or something like that.

I am not sure, as I haven't tried either one, but I have ordered these for a similar issue. can't yet comment on how good they are, as they are still on their way to me. These appear more sophisticated, but as I said, I haven't yet tested them.

Moving your bed close to a support point (such as a structural wall) might reduce the vibrations you feel as well, as the vibrations will typically have the largest amplitude toward the center of the floor span. Finally, I suppose you could try also putting the anti-vibration pads under the posts of your bed. Unfortunately, it is impossible to guarantee that any of these steps will solve the issue, but they might be worth trying.

Some of these anti vibration pads to make the printer quieter, cut up into smaller pieces. I haven't really noticed a big noise difference with these (the concrete blocks I added later made a much bigger difference) but I keep them on there anyways.

I would also suggest a damper on the Y-axis motor, that made a huge difference in noise and vibration.

Yeah my motivation was storage. Sound dampening is a great idea! I stole the idea from someone on thingiverse who thought the same as you. They added vibration dampeners like the ones below, so I added them as well. I like to think it is quieter, which is why I am looking for something else to store underneath instead of replacing them with the original feet.

That's actually a good idea. Put newspaper down and a sponge or two. I bought a nice plastic container on Amazon that has multiple latches. It was kind of pricey but it is what it is. I also bought some anti vibration pads for under the container. I've read that the vibrations from driving can really stress snakes out. I'll include the links below.
