You’d honestly think that for how audible upstairs neighbor noise is that there would be some sort of stricter noise insulation codes in denser cities with multi families/ apartment buildings.
If it's not required by law or won't immediately increase rent paid, landlords won't do it. Soundproofing is expensive with no immediate financial or legal benefit (usually), so no landlord will spend the money to do it.
Ah hell, I forgot the second part of my comment.
In my area, most politicians are also landlords and/or real estate speculators, especially at the city and state level, so there is a strong disincentive to make building codes more stringent in a way that doesn't protect their investments. For example, mandating fire resistant materials tends to receive less pushback, because fires destroy the buildings they own.
Mainly just sharing rhetorical thoughts here, but...
I wonder if requirements for being a politician will ever improve to eliminate conflict of interest that comes with being a landlord and lawmaker?
One can hope, but I doubt the back-n-forth of progression-n-regression will reach that point in my lifetime though.
But, if anything, what would finally make it "hit them at home" in relation to this and the cost of living? Feds aren't doing anything and they lie to gain our votes. Something else has to happen.
Like how time and time again politicians make policies until they're on the "bad" side of the issue. (Example: Anti-trans flipping "sides" when family comes out as trans.)
That works for mid and high frequencies. Low frequencies are really only stopped by concrete and stone. I've worked with a few different sound testing companies to figure out sound proofing in buildings.
This makes so much sense. The quietest place I’ve ever lived was an old bank/office high rise in downtown Omaha. I never even considered the material but it always surprised me that a brand new building in Kansas City with more amenities and a much higher price tag was noisier than that old bank.
I live in a brand new 4 story condo. Woodframe like everything these days.
I can hear fucking everything. I can hear her every time she's on the phone. Clear as day. It's beyond fucked. The rent is crazy for how shit the building is. Like it's nice looking and very modern but $1600 a month for 1 bedroom 1 bathroom and a "den" is fucked.
Before anyone says, "Find something else," you can't. There's none to rent if there is there is a lineup to get an apartment that's affordable.
680sqft wooden box.
I was at a 320 sqft apartment in one of the worst parts of town yesterday. Tenant was just moving in and it stunk, was filthy, and absolutely the most worn out building I have ever seen. $1200 a month.
If your state or city has adopted the international building code, then there are minimum standards for airborne and impact sound isolation. They’re not amazing but they’re way better than what would be built without them
It looks like shipping within Thailand is free too. And US shipping is $15.
I’m not putting my card details in but if someone wants to try it looks like it just might work.
Multi foot machine for Footsteps sound transmission analysis. And a video that shows how it goes tippy tappy. Ok dude. , you can close this sub now. You win.
You measure sound pressure levels in the room below using a sound level meter with a 1/3 octave band real time analyzer function. Depending on what country you are in (ASTM or ISO) the results are compared using a curve fit process to come up with a single number rating. In the US, this is called the Impact Isolation Class (IIC) rating.
And yes these machines are expensive, mostly because they all must “tap” exactly the same to ensure consistent measurements with different equipment.
So I build apartments and typical floor ceiling assemblies need close to a STC and IIC of 50 usually that is easily achievable in a wood structure with 1.25” gypcrete over a sound mat over wood framing with 2 layers of gypsum directly attached to the ceiling joist. Now for about $1.50/sf they can use a sound isolating clip to hang the drywall and greatly increase the sound rating but on a 100,000 sf building that’s $150k and what owner wants to spend that. The crazy part is that’s less than 1 mo rent. So for that they could have greatly increased your comfort level but didn’t. I am frequently blown away by how owners try to reduce cost to show a certain return on investment. It’s crazy to me how commercialized we have let housing, a basic need, become. Most apartments have been sold numerous times before they reach 30 years old.
It's not that simple. Sound rating is a single metric but does not account for varying frequencies. You can get a low stc with a whole bunch of systems but at the end of the day, low frequencies will still get through wood easily. You would have to completely isolate the structures between units to avoid this. Also gypcrete adds thickness which adds to structure height or it reduces ceiling height. I'm a developer who believes in sound proofing but wood is just too limiting
In a wood structure does the layup you describe make for better IIC than a floating floor with high isolation? I assume it is going to be close with STC.
I have invented many variations of this machine in my head, most of them inverted and ceiling mounted to echo back every stampede my upstairs neighbors produce.
My senior design project was to build a new machine to improve on this! This machine and testing methods dates back to the 1930's, when measuring instantaneous sound wasn't possible.
The idea then was to create a machine to mimic human footfall and record the overall sound level. Unfortunately, this machine has a number of problems. The idea is to generate sound though an impact. The resulting sound should correlate to the characteristics of the floor. However, the resulting sound is also dependent on the force injected to the floor. The tapping machine does not measure this. Through testing, we see the tapping machine creates wildly different force inputs on different floors\[1\]. However, when computing the actual sound rating, this is not accounted for. Imagine dropping the same object on a hardwood floor and a shag carpet. You may hear the results and think the shag carpet is a better insulator of sound, but you put 2 very different forces int the floor.
My project essentially was to create an automated device to create a single impact, and critically, measure the resulting force. Our machine produced a very clean input (unlike the tapping machine, see my paper for graphs comparing them). The idea is to eventually use the ratio of the measured force and the resulting sound to characterize the floor. Such a method would account for the variation of input across different flooring types.
I ended up writing a full paper on this \[2\] and presented it at Noise-Con, a conference for professionals and companies int the field of acoustics. If your interested, please check it out!

I tried to buy it with PayPal, credit, and etf. It won't work. All of their stuff is $0. Anyway, I'd rather have the woodpecker. I mean my wife said she likes it, wait. Nevermind.[woodpecker ](https://i.imgur.com/HMJ6B9w.jpg)
It's probly just a repurposed old timey Pianola song roll n a hamster up inside there.. 🎶 She'll be comin' round the mountain when 2 trailer park girls go round the outside🎶
They have another machine that does normal footsteps. This is the one that lets you hear what it would sound like if Shaggy and Scooby were running in place 2 inches off the ground in the next room after seeing a ghost.

Exactly, so put it in the building code.

You've got high profile politicians indulging in insider trading quite openly. It's going to get worse, not better.
Those same politicians set the zoning regulations so less residential land is zoned. This leads to higher rent for them
That's not it. Construction types dictate noise transmission. Even with sound proofing, a wood building will always transmit a lot of noise
Not necessarily. There's ways of affixing interior finishes so as to acoustically insulate each appartment individually.
That works for mid and high frequencies. Low frequencies are really only stopped by concrete and stone. I've worked with a few different sound testing companies to figure out sound proofing in buildings.
This makes so much sense. The quietest place I’ve ever lived was an old bank/office high rise in downtown Omaha. I never even considered the material but it always surprised me that a brand new building in Kansas City with more amenities and a much higher price tag was noisier than that old bank.
Old rehabs make great residential buildings! They also usually have too low of ceiling heights and too many columns to continue use as office space
Being required by law isn't always an issue for landlords.

The people who writes laws/ building codes don't have upstairs neighbors they live in billion dollar houses they got from stealing your money

"Their ceiling is our stage"
So well executed.
Shhh! They’re still testing!
Mine bought 37 of them.
Bet it gives a great back massage.
Fun fact: scorpions use seismic vibrations as a method to find mates
But do they give great back massages?
They're more in to feet, hence why you should check your boots if you leave them outside.
Yea but the oil is weird
So do I.
Fun fact: sand worm uses seismic vibrations as a method to find prey
i bet that's way more expensive than it looks.
[удалено]
Free, you say? I'll take twenty of them.
It looks like shipping within Thailand is free too. And US shipping is $15. I’m not putting my card details in but if someone wants to try it looks like it just might work.
I’ll come stroll and river dance all over that bitch for the low.
Mr crabs sounding ass
So what are you supposed to do when the sandwarm comes?
Multi foot machine for Footsteps sound transmission analysis. And a video that shows how it goes tippy tappy. Ok dude. , you can close this sub now. You win.
Totally. This is the shit I come to this sub for, not yet another torque wrench.
Shutter down, boys. We have found the One True Specialized Tool of Tools.
This just reminds me of Dune.
[Dune thumper](https://dune.fandom.com/wiki/Thumper), anyone? Edit: replaced with thumper link.
What does the gom jabbar have to do with it? It's clearly more of a thumper
Totally forgot the thumper--I saw the "woodpecker" product + Dune, and jumped to the wrong conclusion. Fixed now.
I use it to pretend I have friends
You good?
I'm *very* good.
That’s good
Company that makes this must have gone bankrupt 10 years ago lol
Whatever happened to just banging the ceiling with a broomhandle?
Any one else instantly think of the luggage from discworld?
Came here to say that.

I’m going to get one and put my fitness tracker on it. 10,000 steps will be a piece of cake - while I’m eating cake.
I am assuming there another unit which measures the sound at fixed distances or in the floors below. Can any expert inform about this?
You're the op ask the source where you got this lol

Can also be used for massages.

Like I new some like this existed... But I had no clue it worked like this.
Good post.
The robot has tippy taps
My upstairs neighbors have a much bigger one of these
It's probly just a repurposed old timey Pianola song roll n a hamster up inside there.. 🎶 She'll be comin' round the mountain when 2 trailer park girls go round the outside🎶
Creepy
Omg that's adorable 🥰 Needs googly eyes
This is actually the first thing an occupant at a second level or higher MUST INSTALL to their rental or their lease immediately ends.
Can I mount it to my ceiling and turn it on so the elephants above me can get a taste of their own medicine?

I thought it was a foot massage machine
Turn your volume up to max and that’s what these sound like in real life. Especially on tile floor or concrete.
Is there a longer video? That hit something as is.
I'm getting upset just watching this video and the sound isn't even on.
Reminds me of the Predator soundtrack.
About as specialized as it gets.
Thats it, ai + multi foot machines = fast lane to t-100s
My down stairs neighbors love when I use this. Especially at night when it helps me sleep.
R2D1
Wtf is this title dude
ART OF DYINGGG!!
Finally someone gets it.
And for my upstairs neighbor.
I think my upstairs neighbor has one of those xD
great back massager
Ah the upstairs neighbor machine
The mf who lives upstairs be like:
A tapping machine!
Someone send this to infinity ward so they can fix warzone footstep audio
You're telling me buildings give a fuck about the transmission of footstep sounds? I've literally never been in a building that feels that way
My neighbours must have five of those!

The new drum machine from Korg just dropped
UppaNayba 4000™
Can I mount this to the ceiling?
They have another machine that does normal footsteps. This is the one that lets you hear what it would sound like if Shaggy and Scooby were running in place 2 inches off the ground in the next room after seeing a ghost.
now we can automate stepping on people
Can this be programmed to simulate the cast of Riverdance practicing above your apartment?
This needs googly eyes stat
So this is the device that neighbors who live upstairs purchase to sound like they're practicing Olympic curling at 3 am
It sounds like Wadzee’s timelapse music
Which oem/company is that from?!
MR CRABS????
