r/soundproof

Hi all, I bought a home off a moderately busy commuter road and have been dealing with road noise louder than I anticipated. Spikes around 40-50db with some louder trucks around 60db

Our current windows are 25yrs old double pane double hung. We've gotten 2 quotes and both people provided us with a lot of good honest feedback and prioritization for upgrades. Our road facing windows seem to be in the worst codition, along with 2 other windows which have seals broken in other rooms, so im hopefully the upgrade really helps

The best acoustic option I seem to be finding in the Northeast is Harvey Classic Acoustic STC 34.

We were quoted ~1k per window . I looked into indow inserts but they quoted me ~500 per window and soundproof usa insetts quoted me 2k per window (LOL) so I prefer the window upgrades given the possible resale improvement.

TLDR- Wondering if anyone has experience with upgrading windows, what stc you used and what difference it made for your road noise experience? Thanks!

seems like my neighbors above us are always stomping and rolling around or something. i’d rather avoid confrontation at all costs, so i’m trying to figure out ways we can block the noise a little better without having to say something to them. i’ve seen online about adding dry wall layers to ceilings and walls but we can’t do that in this apartment community. what do you guys do?

I’m building acoustic panels and I have 10 cm thick mineral wool, but my frames are 8.5 cm deep.

Would compressing the mineral wool by 1.5 cm (about 15%) negatively affect its sound absorption performance?

Is this amount of compression okay for an acoustic panel?

I wrapped my entire torso in aluminum foil and bubble wrap to deflect the lawnmower frequencies. Every time I take a step, I pop. The sound is keeping the drywall monster at bay.

Hi,

What is the difference in between these two in terms of sound absorption ?

Built and repaired this DIY Noise Box. 🎛️⚡️ Curious what other noise lovers think about the sounds.

Hello!

I am leaving in a house which share the first floor with the next one. This floor is made of thick concrete which provide a really good system to send all the vibration to my neighboors and act like an amp.

I have tried foam floor with wood, half tennis balls and such under my pedals and i still have a problem with my neighbor and my wife in the leaving room under.

So, I started to look for the Roland Noise Eater system, but it's really expensive! Totally randomly, aliexpress showed me alternatives like:

Aliexpress "noise eater"

What do you guys think about this kind of thing? Did some of you gave it a try?

There is also this kind of passing to put under the feet of the drums rack and maybe the charley:

Aliexpress foam pad

I think I am about to give it a try.

Thanks for your help :)

I recently bought an apartment where I can hear the upstairs neighbours talking and walking. The impact noise is quite loud, while their voices are mostly muffled. After months of research, I decided to renovate one 9 m² room so I would at least have somewhere quiet to go when the noise became overwhelming.

I hired a contractor to install a self-supporting acoustic ceiling. The construction consists of:

-A self-supporting metal frame fixed to the surrounding walls, not suspended from the concrete ceiling

-Approximately 7 cm of empty space between the concrete slab and the metal frame

-Isolation tape between the perimeter metal profiles and the walls

-Knauf acoustifit, 8cm thick

-Two layers of 15 mm fire-rated plasterboard

-Caulk around the perimeter and on every seam

-Staggered/sealed layers, now fully plastered

From what I could see, the installation was done carefully and neatly. However, I am devastated because I can still hear the neighbours’ voices. The room is currently empty, so the voices sound even louder due to the echo. Once it is furnished, I expect them to become muffled again, but that was already how they sounded before I spent €2,000 on the ceiling.

I was not necessarily expecting complete silence from impact noise, but I genuinely expected a significant reduction in airborne voices. At the moment, I cannot perceive any improvement.

Could the remaining voice noise be flanking through the walls rather than coming directly through the concrete ceiling? Could the wall-supported metal frame be picking up vibrations from the walls despite the isolation tape? Is there anything specific I should inspect or ask the contractor about?

I will add photographs of the installation. I would really appreciate advice from anyone experienced with building acoustics or similar ceiling systems.

How do I soundproof my room so newborn won’t wake the whole house up ?

Any tips or tricks

Hey Guys,

I'm living in a basement apartment, and the stairs open directly into the main floor's lounge. My landlord won't allow a permanent door installation, so I'm looking for DIY, temporary, and renter-friendly solutions to get some much-needed privacy and sound dampening (the noise from the main floor is too loud and disturbing).

I'm open to creative ideas!

Hi

There is an gym above my floor and we get lot of sound and vibration when someone throws the dumbbell or do deadlift.

We have been considering to do some treatment on our ceiling to reduce the sound and have called few vendors. Possible options which we could understand is

1. MLV sheet on the ceiling and then bass bloc layer
2. Rockwool layer only

I know the best thing to do would be in the flooring of the gym but we don't know when that will happen and this is delaying our project.

What would be the best treatment to do to reduce the noise?

How do I fill the 1/8” gap around the sides of my new door?

Wall has Safe’n’sound batting and 5/8” Quietrock drywall on both sides. Solid core door, but the jamb is sitting here with big open sides. The top is about 5/8 actually, so may just fill that with scrap quietrock.

GC recommended spray foam. Are there sound proofing spray products?

I am an interventionist at a k-5 school. My office is in an interior room with no windows, across from the second grade classrooms and bathrooms. Every year I struggle with hallway noise that interferes with my instruction. I’m looking to buy a sound machine that is under $50 that alleviates the issue. Anyone in a similar situation have one that they love?

Hi all. I've been doing research on laminated glass window inserts to quiet down the sounds of screaming toddlers next door, and I came across Soundproof Windows Inc. They seem to be significantly cheaper than any of the other companies that I've spoken to (e.g. - CitiQuiet). They're telling me that right now bow, they're offering 10% off with an additional 10% discount on top for each of their glass thicknesses (1/4, 3/8, 5/8). My question is, is this the cheapest that they get? The sales rep that I spoke with doesn't seem to be able to negotiate any further down, so I'm wondering if anyone else can comment on whether this is the best discount one can expect on these.

normal lang ba to sa mga condos? 😭 i rented a unit dito sa isang condo sa QC for review purposes (malapit siya sa review center ko) I've been staying for 2 weeks now and hindi ko na mapigilan mabother kasi bakit naman super rinig na rinig ang katabing mga units huhu

I know isang wall lang ang pagitan and the probability na marinig ang mga noises is high talaga. Pero teh naman kasi, every weekend sa katabi kong unit may nangyayaring milagro 😭 Hindi lang once. Sa buong araw ng saturday and sunday, halos nakakailang rounds sila from afternoon to midnight. Kahit early morning ng sunday, may nangyayari din.

Nagtry na ko magpamusic na lang para hindi marinig kaso yung ingay ng kama nila pati sigaw ng babae, rinig na rinig samin huhu lumipat nga ako dito para makafocus din sana sa pag-aral kaso ganto pala jusq

Di ko naman mababawalan sila sa ganun kasi normal naman at baka kelangan talaga nila yun after a whole week of work hahsjjsk pero guys, ano pwede ko gawin? 😭 ako na lang ba mag-adjust?? hmay way ba para mabawasan yung sounds na marinig dito sa unit na nirent ko? genuine question huhu

Hi all — I’m trying to improve speech privacy in a rented office without making major or permanent modifications.

The main issue seems to be the door, which has glass panes plus gaps around the sides and underneath. I can’t replace the door or alter the walls/frame, so I’m looking for removable or minimally invasive options.

I’ve been considering rubber/neoprene perimeter seals, a door sweep or automatic drop seal, and possibly an acoustic curtain/blanket.

What would give me the biggest improvement in keeping conversations from being intelligible in the hallway? I’d especially appreciate specific product recommendations that actually work acoustically.

If I’m prioritizing, should I tackle air gaps first, then the bottom of the door, then add mass/absorption?

Thank you! I should also mention there will be white noise machines both in and outside of the office.
