You're welcome. There's a lot to dig into with this particular research project and I only scratched the surface. I think lab-tested is more reliable, and I'll look for more examples like this one. They usually need an "interpreter" to simplify the info.
Found your video on a search for rubber vs Eva, which is better at vibration isolation. I hope you don't mind giving me your suggestion for my situation. I live in a condo and when my downstairs neighbors shut their front door I feel a strong vibration throughout my floor. I sit in one spot most of the time and was thinking if I purchased a large rubber mat, ,some Eva foam tiles interlocked on top of the mat and then a sheet of plywood so I can use my roller office chair. Possibly another rubber sheet on top of those layers. Do you think this combination would minimize the vibration? I have left a note for the down stairs neighbors to close their front door gently but only get minimal success with that. Thank you and sorry for the long message.
Several viewers have asked me if they can reduce vibrations (from an outside source) by putting their furniture on anti-vibration pads. My first instinct is to say "no," because the vibrations and resonance are already in the building frame, and you're not stopping them at the source. Anti-vibration pads should be placed between the offending source (say, a washing machine or an HVAC system) and the structure . But I understand what you're trying to do... you want to create a buffer, a float, where you sit. My guess is that you'll still hear (and feel) that door slam on a rubber mat because the framing is moving underneath you. It's totally normal to feel frustrated with your neighbors, since they're not helping. They might not be actually slamming the door. -- maybe it's helped by air pressure (wind). One suggestion: you could offer them some strips of thin, closed-cell foam weatherstripping (or felt) to line the inside of their door frame. Maybe a thin strip of foam would enable a softer close, in the same way that it can reduce the slamming sound on cabinet drawers. Of course if the door is really snug in the doorframe already, it might cause them to slam it harder. I don't want to discourage you from trying your experiment. But I also don't want to raise your hopes that it will resolve the issue. Think of it this way: if there was an earthquake and your chair was on a rubber anti-vibration pad, would you still feel the earthquake? Yes.
Thank you for the thoughtful reply. The unit below me was vacant for a least a year and now it has been sold so a lot more in and out of the door lately (trades people in and out and the final clean up etc.) which reawoke the situation that I had relief from. Those of us that have lived here a while have for the most part learned to keep all noises to a minimum, including bringing the front door to the door jamb and just push slightly till you hear the click of the latch bolt spring into the strike plate opening. I don't hear the closing of their door but the vibration is enough to send a slight tremblor through my floor. So the wood work, joists and door framing must at some point be loose or my flooring (laminate) is not properly adhereing to the subfloor. Of course any banging on the structure would produce a vibration. My new downstairs neighbor is moving in later this week so I'll see how it goes before any purchases. From my observation some people are just naturally noisy and some are not and those that are noisy just do not hear or feel what other people are sensetive to, a kind of numbness that is somewhat enviable, but then again not. You are right that I want to make a floating island and hope that the rubber mat and eva tiles would disipate the vibration. Probably wishful thinking, but maybe provide a little placebo effect. Thanks again.@@soundproofist
@@lostinthekerf I have a similar issue in my building. If a downstairs neighbor slams the door, it makes a loud bang and rocks the upstairs apartments. It can happen from a gust of wind, or if they have visitors who enter/exit as if it was a barn in the middle of nowhere. When a new resident moves in, they sometimes need to be informed about the building acoustics. For example, I'm intentionally quiet and light-footed, and I have carpeted walking paths. So they might assume -- since they don't hear me -- that there's no noise transfer between our units. They can get defensive and express disbelief if they're told that their activities can be heard loudly upstairs, like slamming doors & drawers, pounding feet, party conversation, etc. Or they accuse the neighbor of being overly sensitive. It's a challenge, for sure. I totally understand why you want to build a placebo!
Thank you for the excellent information in your videos!
Thank you, also... and you're welcome!
thanks for this. im about to start some soundproofing in my ground floor apartment and every bit of research helps
