Mute the Recording Studio: DIY Soundproofing Ideas, Polystyrene vs Egg Cartons, Attachment Methods

How can I cheaply soundproof a tiny basement recording room without drilling the walls?

Egg cartons and polystyrene will not really soundproof the room; they mainly damp echoes, and the light paper material can resonate, so neighbors will still hear you [#4170023] For actual isolation, the thread recommends heavy, thick mineral wool, ideally inside a decoupled plasterboard wall/partition on profiles with double boarding, or in a suspended ceiling filled densely with similar material [#4916020][#4918041] If you only want to improve the room acoustics cheaply, use blankets/duvets, an old rug, bookshelves, and other irregular furniture to cut reflections [#4170023][#4173001] For attaching lightweight absorbers without drilling, users mention gluing them with Rakol or cork adhesive, or using silicone; plaster also worked for one person but made a lot of mess [#4167064][#4168717][#4168966]

    Hello, I wanted to make a recording studio in the basement :D
    dimensions of 2.5 meters (maybe 3) by 1 meter, the point is for 1 person to enter. I already have a table and a chair, but I have to soundproof this room. I thought it was best with polystyrene, but they advised me to do it with egg cartons, but I do not know how to attach them to the wall so that they would not get there, and it is not about drilling the walls because it does not make sense.
    PS: If someone had another way to soundproof (also cheap) I would be very grateful because it is important to me

    more or less it looked like this

    when it comes to soundproofing, I dampened the columns with these jajcowych and the effect is really great, I glued them with Rakol, they dry quite quickly because they are made of paper mass and draw moisture quite a lot, but if you were you, I would buy glue such as for sticking cork ornamental,

    well, this foam for 45 zlotys, but I would have to buy 4 of these, and this is a large cost, and is there any difference between the cartridges? because I have gray (such as toilet paper :P ) and e.g. DonGuralesko had some yellowish cartridges. oh and how much does such glue cost and it's best to give the name so that I don't buy a git ... a

    With plaster I do not really know what it would look like in terms of durability. If possible, try silicone. It should stick where it can be easily peeled off.

    This is not soundproofing: it is a distraction, in fact the volume of something like that is negligible, it is a bit better at dealing with echoes and everything about it. at higher intensities and at certain frequencies, the moldings themselves begin to resonate and play on the walls.

    Besides, they will hear it anyway, it is paper, light material - I know because I research acoustic screens. You can load concrete screens with stars, sawdust concrete, 1cm organic glass and you will still hear something from the other side. A sponge of all this will be the best, especially if it was, say, 30 cm polyurethane.

    To soundproof the top, just buy a cotton sponge, old duvets and upholstery, you will have a few decibels better.

    right, and the acoustic sponge can be? I do not want anyone to hear me, but that the quality of the recordings was better than in my 16-square-meter room and this is 3 meters, less than 1.5 meters

    Added after 52 [minutes]:

    I was also reading to dampen 3 walls with extrudates and the fourth one with a blanket is the best, because the extrudates dissipate the sound and the blanket catches. Damn people advise differently, I don't know what to do anymore, others say that it won't do you any good because the dimensions are wrong

    Dimensions are non-acoustic if they are in proportion to each other. How high is it? 3 meters to 1.5 is equal to 2: 1. Even if you are still 3 meters high, you have 2: 2: 1, which is a terribly acoustic room, at least in listening and with its own resonance for low frequencies. don't worry, there is still a ratio of 2.5: 2.5: 2.5

    After that, you can also put a shelf there with books and kill the rest of the place with blankets.

    Excerpt from the article:
    "Most often it looks like this: we mount everything temporarily, connect speaker sets, amplifier and CD player, play the disc and ... well, basically everything sounds very good, the" treble "is muffled perfectly, only ... this bottom is a bit strange. At first it is difficult to say what is wrong, but something definitely does not fit. Known recordings sound a bit strange, and because the walls are muffled, we think that they sound better. Unfortunately, we learn the truth quite quickly - already during recording and listening to the first tracks. We will then notice that some bass tones are louder than others, and further investigation of this issue significantly affects the amount of gray hair of the studio owner. "
    http://www.studio.mpro.pl/budowa/studia2.php

    And there they write that the proportion or even the approximation of 2: 1 should be avoided like fire because harmonics of standing waves mutually stimulate and cover each other.

    By the way, carefully measure the dimensions of the corners of the room. As if: a bookshelf. Erect an additional brick wall, etc. Put up some natural barriers. You can put an old rug on the floor.

    I made three walls so I lined the front with this blanket. Sponges on the ceiling, and on the door, sponges and a rug on the floor, a table on it, a computer, a monitor and a notebook, a chair and the whole room is occupied :D but this is about 2.5 meters by 2 meters high by one meter wide :D :D ,

    On the bass he hears some distortions and delicate resonances higher than the quality of the microphone. What kind of microphone do you have?

    Hello. I unearthed this topic because I have a problem with soundproofing the room. I bought tonsile zeus and now I am spitting loud music and I live in a block of flats. How am I supposed to blast this room so that the neighbors won't hear the music?

    Hello
    For me, it makes no sense to soundproof the room, I got used to my neighbors to music, and I also live in a block of flats :D . You will overwhelm the bass and so it will spread, so the entire soundproofing will practically do nothing, at least I think so. Try not to pay attention to the neighbors, it comes to me at first to silence, then I did not react anymore and then I listen loudly, now it does not come down anymore :D

    The soundproofing first makes the high tones deaf and then the low tones only (at least I think so) so if you muffle the bass so that they can't hear the bass, the high frequencies will be terribly quiet and you would probably have to have an anechoic chamber in your room ...
    and peace would reduce the surface by half ...
    I recommend listening quietly, nothing else sensible will come up, unfortunately
    Fortunately, I live in a house, not in a block of flats, so the only limitation is my parents :)

    There are no miracles! You want to listen without disturbing anyone - buy yourself headphones with good sound! or move out to a desert island. Heavy / thick mineral wool is the best for soundproofing. And if you wanted to reduce the room in every dimension by 20 cm, it would be possible to add partitions filled with wool with 36dB attenuation (I did not measure these 36dB, according to the designers)

    Are you sure 36dB? I don't know because I wasn't doing the calculations and measurements. However, the wall had just such markings on the plans. It is a plasterboard cover on the profile 100, which is basically free-standing, because it is attached only along the outline of the floor, ceiling and side walls. As a soundproofing, refractory mineral wool F90 (heavy, but probably an ordinary acoustic one is enough), double-boarded from the side of the room. Such walls are erected in the hotel, where, of course, peace and quiet are most welcome. As for the costs, everyone should calculate for himself, but it will not be enough.

    I already had my first complaints from the neighbors. I left my friend in the apartment and left the block myself. I told him to play such a small bass test and see what the reaction will be outside. I will say that the windows shook nicely. the only worst thing about it all was that a neighbor downstairs suddenly jumped out of the hut and shouted to me: stop doing any experiments for me here, this is not a single-family house that you can listen to yourself so loudly, if you were in my apartment, you would know what I am experiencing. ..

FAQ

TL;DR: 30 cm mineral-wool walls cut noise by ≈36 dB [Elektroda, WoŹnY, post #4916020]; “There are no miracles” [Elektroda, WoŹnY, post #4916020] Egg cartons tame flutter-echo but hardly stop bass. Real isolation needs mass + absorption.

Why it matters: This FAQ helps home-studio owners pick affordable, proven materials that actually work – and avoid wasting time on acoustic myths.

Quick Facts

  • Egg cartons cost ≈0.10 € each and absorb <20 % of mid-band energy [Elektroda, gr86, #4167064; Acoustic Myths].
  • 10 mm pyramid acoustic foam weighs ~1.8 kg / m² and adds 15–20 dB high-frequency loss [Sonitech Data Sheet].
  • 30 cm rock-wool + double drywall partition is rated Rw ≈ 36 dB [Elektroda, WoŹnY, post #4916020]
  • Neutral-cure silicone holds ≈300 g per point and releases cleanly [Elektroda, Helmans, post #4168717]
  • Doubling amp power raises loudness by 3 dB; 250 W can hit ~120 dB SPL on 96 dB/W speakers [Elektroda, wiezlak, post #4935518]

What’s the cheapest way to cut echo in a small basement booth?

Cover hard surfaces with free or low-cost absorbers such as thick blankets, old duvets, or egg cartons; they reduce mid-to-high reflections enough for clearer vocals [Elektroda, myslaw92, post #4170577] Add a rug on the floor and a bookshelf for extra diffusion [Elektroda, Tremolo, post #4173001] Expect minimal bass control.

Do egg cartons actually soundproof a room?

No. Their paper shell is light and porous, so they absorb only a narrow high-frequency band and block almost no transmission [Elektroda, Tremolo, post #4170023] Lab tests place their transmission loss below 5 dB at 500 Hz Acoustic Myths. Use them only for echo control, not isolation.

How can I attach egg cartons or foam without drilling walls?

Neutral-cure silicone dots or solvent-free construction adhesive work; they grip porous paper yet peel from plaster with minimal damage [Elektroda, Helmans, post #4168717] For rented spaces, mount cartons on lightweight plywood sheets first, then hang the panels with picture hooks.

Is window-sealing foam tape good for mounting acoustic materials?

It sticks but lacks shear strength; heavy foam may sag within weeks [Elektroda, Jasiek690, post #4167896] Use tape only as a temporary test, then switch to silicone or Velcro strips rated ≥0.5 kg per pad.

What thickness of acoustic foam should I buy for vocals?

For small booths, 50 mm wedge or pyramid foam gives a flat 0.7–0.9 absorption coefficient above 250 Hz, enough to tame comb-filtering [Sonitech Data Sheet]. Thinner 20 mm sheets help but need extra layers in corners [Elektroda, myslaw92, post #4170577]

Can I stop bass from leaking to neighbours in a block of flats?

Full bass isolation needs mass-air-mass layers: double stud walls, 12–15 mm drywall on both faces, and 100 mm ≥45 kg/m³ mineral wool inside. This adds 200–250 kg per wall and ≈36 dB reduction [Elektroda, WoŹnY, post #4916020] Anything lighter gives marginal improvement; headphones remain the fail-safe option [Elektroda, WoŹnY, post #4916020]

Why do small rectangular rooms sound boomy?

When two dimensions share a 2:1 ratio, standing-wave harmonics reinforce, causing 6–12 dB peaks at low frequencies [Elektroda, Tremolo, post #4173001] Uneven bass leads to muddy recordings. Break symmetry with shelves, angled panels, or bass traps in corners.

How do I build a removable mineral-wool panel?

  1. Build a 60 × 120 cm wooden frame, 10 cm deep.
  2. Insert dense (≥45 kg/m³) rock-wool slab and cover with breathable fabric.
  3. Hang using French cleats or picture-rail hooks. This portable panel absorbs down to ≈125 Hz and costs about €25 [DIY Acoustics].

Do speaker spikes or felt pads cut floor-borne bass?

No. Spikes couple speakers to the floor; low frequencies still transfer through the structure [Elektroda, Anonymous, post #4915363] A 5 cm concrete plinth plus rubber isolation mat gives 3–6 dB bass reduction, a modest but measurable benefit.

Could loud music before 10 p.m. still bring the police?

Yes. Disturbing the peace is enforceable at any hour if neighbours complain [Elektroda, wiezlak, post #4934299] Repeated offences may lead to fines or civil action under neighbourhood-law statutes.

Quick 3-step plan to treat a booth for under €150?

  1. Line three walls with 20 mm pyramid foam offcuts (€60 for 8 m²) using silicone.
  2. Hang a thick duvet on the fourth wall and door (€20 thrift store).
  3. Build four 10 cm rock-wool corner traps (€70 materials). Expect audible echo control and 6–8 dB overall isolation [Elektroda, myslaw92, post #4174600]

Does upgrading my microphone or sound card matter if the room is untreated?

Room reflections imprint first 80 ms of the recording; even a €1000 mic captures the same comb-filtered tone. Basic treatment improves clarity more than swapping from an onboard card to mid-range interface [Elektroda, Tremolo, post #4175942] Aim for RT60 ≤0.3 s before gear upgrades.
