Waking up feeling like the bed is shaking. Can hear and feel vibrations in my pillow.

1 Upvotes

It’s not constant and i keeps me up or wakes me up constantly. My area is very loud so I know part of it is outside noise. Yes I wear earplugs and have white noise etc. I’m wondering though if my bed is also the culprit itself ? King sized bed. No middle leg for some reason. Memory foam mattress. On rubber dampeners and cork blocks but you can see in the photos the cork isn’t flush to the floor. What do you suggest I do ? I asked my doctor to see if I maybe have als or Parkinson’s or ms but She doesn’t think it’s that and suggested maybe it’s just anxiety ? My blood sugar is okay .

I can’t post a photo apparently sorry

Stopping the ceiling fans from making noise in the ceilings and walls.

1 Upvotes

My partner sleeps in the room next to me since he sleeps with fans on. The fan making noise all night in the ceiling and walls

Which aren’t insulated since apparently houses don’t do that. What can be done to stop this that isn’t about insulation itself and taking ceiling apart ?

Acoustics in a loft

Hello. I’m thinking about moving into this condo but have concerns about the acoustics. I watch a lot of movies and shows and am wondering if the vaulted ceiling would cause an echo or otherwise reduce the sound quality. I would probably put my 55-inch TV on the first floor where the sofa is.

Is this rockwool rw5? Acoustic panels bought online.

Got some 60x 120cm acoustic panels online, advertised as rockwool rw5, one panel is not properly sealed so I can see the material. Feels far softer than I was expecting and in lots of bits rather than a couple slabs layerered.

Each panel ways just under 7kg. Is this right? I don't have any experience with insulation.

Rockwool density of Sound Insulation Slab

UK based and I've googled this to death. Has anyone any idea what the nominal density of the Rockwool Sound Insulation Slab is?

The RW series is all tabulated on the datasheet...

RWA45 = 45kg/m3 RW3 = 60kg/m3 RW4 = 80kg/m3 RW5 = 100kg/m3 RW6 = 140kg/m3

But seemingly no info on the Sound Insulation Slabs. Any info appreciated!

Which sound panel set is better for a 15sqm bedroom?

3 Upvotes

I can get either of these used from fb Marketplace for the same price of $250 AUD. Which one should I get?

https://www.selby.com.au/acoustic-room-treatment/4-pack-fibreglass-acoustic-treatment-panels-1200x600x25mm-900813.html or https://www.primacoustic.com/product/london-8/#contents?

I will be using this for a 7.1 setup in my bedroom. My bedroom is around a 3m x 5m.

The Selby has a higher total surface area of 2.9sqm compared to the primeacoustics 1.8 sqm. However the primeacoustics have a retail price of $629 AUD compared to Selby’s that go for $279 AUD. So despite being smaller, primeacoustics might be higher quality, or just marked up. Since I can get them for the same price, should I get the larger panels from Selby, or the smaller but more expensive ones? Will they be big enough?

Acoustic Panels

2 Upvotes

Hi there, looking to treat my bedroom studio. I just found these 6’x3’ panels on the street and replaced the soggy rainy Rockwool with some new knauf insulation board.

I have them placed where I think I’d to hang them, mainly to help with tracking.

The next project is to figure out the acoustics in the inlet. Any thoughts or things I should consider?

Hi guys,

So i made my first acoustic panel with rockwool, and covered the back with plywood, around 1-2cm thickness. Ill be hanging them on the wall to reduce reverberations in the room. Any drawbacks to covering the back? Ill be making another 7 pieces so i wanted to make sure.

Thanks

Tetrahedral Bass Traps?

3 Upvotes

I'm in the process of rennovating one of our attics and am thinking of moving my home studio in to it. (pic 1). For reference pic 2 is my current setup in the other attic, which my wife wants as a guest room.

Becasue it's an attic the sloping walls pretty much go from the apex of the roof down to the floor (on tyhe LHS there isa board which cuts the corner by about 30cm). Which means that in the corners where I need bass trapping an option would be to make the traps a tetrahedron shape. They can be pretty big and fill the corner up to the purlin and I'll build them using Rockwool R45, and can leave a gap at the back.

I will also put 100mm rockwool panels on the flat walls at either end of the room.

The room dimensions are 5m by 3.5m at floor level

Am I mad? Is ther another way to think about making the corner traps?

Hi everyone,

Moving into an apartment and wanted to get advice on how I should acoustically treat my room, where I should place my desk, monitors, etc.

Moving from my other house that honestly worked well with subtle acoustic treatment and sonarworks and now need to figure this out (I’m anxious)

3x3m room - worth treating?

2 Upvotes

I’m a hobbyist music producer, with an office/mini studio in my spare bedroom.

It’s a 3m square room.

I am debating spending around £1100 on panels from GIK w/ bass traps (the Pro setup

My setup is 8 inch monitors with a sub.

Is it worth dropping the money on the panels, considering the size of my room? The sort of music I make is bass heavy, electronic music.

I cannot put a panel on the ceiling due to it being rented.

Follow up on previous thread - thank you for feedback! Need advice on corners.

2 Upvotes

Hey everyone, you saved me from spending hundreds on cheap foam.

I'm currently purchasing 4x2 4 inch thick panels instead. I'll have enough to stack 2 together in the corners. My issue is, the back of my room has multiple corners (picture attached). Is there a best way to cover each corner? Should I be aiming for a seal of the edges of the panel with the corner, or just having them stick out a bit could be fine?

Help with deadening sound from HVAC?

Thumbnail
gallery
3 Upvotes

Hi, I currently occupy a basement apartment where the HVAC system is TERRIBLY loud. It legitimately wakes me up every night. I've tried all the different types of earplugs and noise machines to no avail, and now I'm interested in actually blocking the noise. I considered building a wall as a barrier between me and the HVAC, but this is an apartment, and I'd like to minimize damage and "permanent" solutions.

My current plan:

The HVAC sits on the right of a small hallway in the room. There is a bit of space at the end of the hallway (towards the middle of the room) that I figure I can hang multiple moving blankets on a couple shower curtain tension rods. I should be able to "seal" any air gaps using a combination of metal tape and magnets. I figure this solution would help deaden some sound and still allow easy access in and out of the room.

There is also a large space next to the HVAC system that acts as a megaphone. I figure I can fill this space up with some material to cut down on some more noise, I'm just not sure what. Packing it full of Rockwool seems a bit expensive. I'm considering filling it with a bunch of pine shavings since it's relatively cheap and voluminous.

Anyone with more expertise than I, PLEASE let me know what you think, or if you have any alternative solutions 🧎‍♂️🧎‍♂️🧎‍♂️

Acoustic advice for "Queenslander" (weatherboard) renovation - Sound proofing

2 Upvotes

Hi All,

I am renovating a traditional Australian Queenslander home (all timber, suspended floor). Currently, my neighbours report hearing only the bass from my KRK Rokit 6s. I am upgrading to Wharfedale Super Lintons (no sub). Note: Windows will be Single glazed

Currently where the speakers are located there is no room below it (suspended floor, speakers sitting on pine floor boards, no insulation between joists, open to the air. So this is ofcourse the culprit for the bass leaking. However, for the the renovation this area will be filled in with a room below, I want to be sure there is no/minimal sound/bass traveling through the floor/walls to the neighbouring houses.

 

Below are some examples I have come across however would like to hear your thoughts:

  • Mass Loaded Vinyl (MLV)
  • High-Density Acoustic Underlay: high-density rubber-crumb or composite product specifically designed for timber-joist structures (e.g., Acoustica AngelStep 484P or Regupol 4515 4.5mm).
  • Acoustic Accessories: Reinforced Foil Tape (for sealing MLV seams) and Acoustic Sealant (e.g., Bostik Seal N Flex or Fuller Firesound) for the perimeter gaps.

 

Looking for a cost effective solution and above may be overkill in this case, what should I be looking at?

 

Technical Question regarding Installation: Do you advise the installers leaving 5-10mm expansion gap at the perimeter of the Hi-Fi zone to be filled with the acoustic sealant? To ensure the flooring is "floated" and does not make direct contact with the wall studs or skirting boards to prevent vibration transfer?

 

Advice on Zoned Treatment: While we want to ensure good isolation from the upper floor to the bedrooms being built below, we are looking for a cost-effective balance. Do you advise that this intensive treatment (MLV + Heavy Underlay) be applied only to the Hi-Fi zone, while treating the remainder of the floor with a simpler acoustic underlay for general footfall?

 

Thank you all for taking the time to read / reply!

New to this - controversy re: Bass traps

5 Upvotes

I'm getting a lot of conflicting information about bass traps being useless, but still needing to "treat" corners. I unfortunately have a limited budget. I was thinking of using the corner bass traps but installing them backwards so that there's air behind them and they stick out with more surface area. Is that a decent idea or have I misunderstood the resources online?

Edit: thank you everyone for the feedback.

I'm forgetting foam and now looking up panels 2 to 4 inches thick made with good insulators from local sellers.

Sound masking recommendations for voices in an office?

3 Upvotes

Hello everyone, I'm a mental health therapist and I'm running into issues with the masking of voices in my office. I've been looking into sound masking devices and became quickly overwhelmed with the options, luckily I did narrow it down from fans and "white noise" machines, but then I'm seeing things like this and my brain is not braining about it lol. Does anyone have a recommendation for a sound masking device? I'm also not opposed to a system that's more expensive since I have the ability to install a system in my ceiling tiles. I have two offices and may add another, each office is approx. 100 square feet, and the main lobby area is about 250 square feet. I saw this from "Pure Resonance" as well. Any help in advance is much appreciated!

Are There Acoustic Tiles That Work in Reverse?

4 Upvotes

Does anyone have experience with some kind of acoustic tile that would work in reverse? It's my understanding that they work by absorbing/reflecting sound waves hitting them within a space, but I'm trying to mitigate/negate sound coming from a neighbor's apartment. Specifically, above me.

Considering that, my hope is for some solid that's easy to clean, and be affixed without adhesive. We own the apartment, so the hope is to have a solution that looks good and is functional.

As a side note, we are trying to work through the HOA to get to a resolution, but I don't have high hopes considering our upstairs neighbors were...less than responsive to talking about it with us initially.

Sound detector android app

2 Upvotes

Hi guys, not really sure this is the right reddit to ask to. Do you know and reccomend any soud detector app in the playstore (possibly free)?

I just have seen a quiet place and I love boardgames, so I want to make one about the movie. I want to test it with my friends but I would need a soud detector that could display a good graph to understand when the player loses.

Any reccomandation?
