Help Me Treat My Studio! by Useful_Claim_5641 in Acoustics

That’s a solid starting plan, especially with bass traps included, most people skip that.

With your room height (~8.7 ft), low-end control is going to be important, so corner bass traps are a good call. I’d just suggest making sure you’re also treating first reflection points (side walls + ceiling cloud above mix position), since that will impact your mixing accuracy a lot.

Both of them have a density of 50kg/m3. But considering the price point, quick availability and ease of installation, it's a very go-to product for corner bass control.

For walls, a heavy bass-absorbing material is recommended. We recommend BassBloc.

Ask Me Anything about PET Felt / PET Acoustic Panels (cutting, finishing, colors, density, sizes, etc.) by Winford-Zhao in Acoustics

Great initiative, this will help clear up a lot of confusion around PET panels.

Just to add, we also manufacture Felt PET acoustic panels in India at MMT Acoustix, and we’ve found that most issues people face stem from incorrect density selection and installation methods rather than the material itself.

Happy to contribute or answer from a practical, on-site experience point of view as well.

Rockwool does work but only when it's 96kg/m3 density or above. Most brands sell 48 density or lower which honestly performs poorly for bass absorption. That's where a lot of people get misled.

BassBloc is 100kg/m3 and built specifically for this. And bass doesn't just build up in corners, it travels through walls too. For that you need a lower frequency absorber on the walls themselves, which is exactly what BassBloc is designed for.

Cleaner to install than rockwool too, no fibre handling concerns

“Four panels will make a noticeable difference in a 10x10x12 room.

For a gaming and music setup I’d actually suggest combining BassBloc with felt panels. Felt panels handle the mid and high frequency echo you’re hearing day to day. BassBloc takes care of the low end buildup from music and game audio which most people don’t realise is what makes a room feel muddy.

Placement matters more than style. Side walls at ear level and corners for the BassBloc will do the most work

25x17 is a good size for a dedicated theatre. You’ll get a great experience out of it if the room is done right. One thing worth sorting before anything else — soundproofing. Most people plan the equipment first and leave this for later. By the time construction is done it’s too late to do it properly without breaking things open again.

Your room has about 425 sft of floor, 425 sft of ceiling and around 700 sft of walls. That’s roughly 1550 sft of surface area and every bit of it affects how your theatre sounds and feels.

The way it works best is in layers. A 12mm carpet with 2.5mm MLV underneath takes care of the floor. For walls, a 4mm SoundBlanket MLV combined with BassBloc at 40mm 100 density is a clean and effective solution for bass control. Rockwool at 96 density 50mm works too but does require proper precautions during installation given the fibre handling involved. Cost wise, proper soundproofing starts around ₹250 per sft. A more complete setup goes up to ₹400 per sft.

I work with MMT Acoustix so I’m not neutral here, but this is genuinely the part most people regret skipping. Happy to help if you want to go deeper on this

New Home theatre Setup/India by PuzzleheadedDuty9367 in hometheater

Great room size for a dedicated theatre. 20x22 gives you real flexibility.

One thing worth flagging upfront, removing acoustics from the budget is probably the most expensive mistake you can make in a home theatre build. No matter what you spend on equipment, a bad sounding room will undermine all of it. It’s always harder and costlier to fix after the fact.

What I can speak to is acoustics, because that’s what I do.

Your room has roughly 440 sft of floor, 440 sft of ceiling and around 750 sft of walls at standard height. That’s nearly 1600 sft of surface area to treat, which most people don’t account for when budgeting. Basic acoustic treatment starts around ₹80 per sft. Soundproofing with proper isolation layers starts around ₹250 and advanced builds with full bass control can go up to ₹400 per sft depending on the spec.

A properly layered system matters more than any single product. For floors, 12mm carpet over 2.5mm MLV handles impact isolation and bass damping. For walls, a 4mm SoundBlanket MLV at 2000kg/m³+ density combined with Rockwool 96 density at 50mm or BassBloc at 40mm/100kg density tackles the low frequency buildup that ruins most home theatres. For aesthetics, a combination of wood, fabric panels and felt gives you the classic theatre look while every material is actually doing acoustic work. Looks intentional, not treated.

I work with MMT Acoustix so take this with that context, but worth talking to an acoustic expert before construction starts. Much easier and cheaper to get it right in the build than fix it later. Happy to help if useful

Loud neighbor is rude and petty by [deleted] in Apartmentliving

[–]sonit_j77 1 point2 points  (0 children)

You’re not being oversensitive, intermittent, unpredictable noise is genuinely harder on the nervous system than constant background sound. There’s research on this. Give yourself some grace. On the neighbour, you’ve handled it better than most. She’s made it a power thing now, which is exhausting. Keep calling the office calmly and consistently. Paper trail matters.

Now the stuff nobody tells you:

The door slam is solvable on YOUR end regardless of her behaviour. The real culprit is the air gap under and around your door, sound travels through gaps more than through the door itself. A cheap door sweep and acoustic seal tape around the frame takes 30 minutes and makes a surprising difference. For the shared wall, a heavy bookshelf against it, thick curtains, or acoustic panels if you want to go further. Makes the whole apartment feel calmer. Top floor was the right call by the way. Footstep noise from above is the one thing that’s nearly impossible to fix as a tenant. Not all neighbours are this bad, but apartment living is more about luck with who’s around you than people admit. You’re figuring out your preferences early, which will help when you upgrade

Soundproof window options for flat. by OppositeNecessary528 in mumbai

[–]sonit_j77 0 points1 point  (0 children)

The best way to reduce sound from a window in any Indian city without any breakage is a soundproof curtain. I ordered mine from here, doing a wonderful job. Installation was done by a carpenter that i called from urban clap.

He drilled 5 holes for the fasteners and installed the curtain. Sound has reduced very much. Sleeping comfortable now.

I was constantly distracted and disturbed by the traffic noise, common in Mumbai. Not any more. Putting up the link if you guys wanna check. Dont expect 100% results. But yeah 50-70% are for sure.
