[glennjv]

Ang nakita ko lang color sa ordering section, blue, yellow and nagulat ako may california grey (tawag nila)

I asked if
May smaller cut = wala
1 side lang = di pwede
So binili ko na rin.

Sinwerte ako kasi di daw yun ginagawa regularly. May stock nung pumunta ako ng 9am ng sat. Got it in 15mins. Ang SLA nila 2hrs if madami tao.

If wala stock. SLA is 3 days.

Sa 1 side ng 44x80 i was able to cut
6pcs of 18"x18" square, 2pcs 15" x 24"

Kaya 8pcs 18"x18" plus small scraps

ano pinang cut mo sir? thanks sa reply.

[glennjv]

Yes dalawa. It comes in pairs.

Mukha siyang isang normal rectangular na foam na hinati sa gitna.

[glennjv]

ano pinang cut mo sir? thanks sa reply.

Metro tapos pentel pen to mark.

12 inch ruler plus cutter.

Extend ko yung cutter to the longest setting.
i cut from the flat side. Baliktad.

1 smooth action na mga 1inch deep. (Dont hack na parang lagare, dapat parang knife/slicing action)

Napansin ko pag lagare/hacking panget edges.
Pag slicing smooth.

I just pull na cut na foam apart and slice yung dulo/tip na hindi na cut.

Sir, kung around P3,300 yung grey foam, di ba mas mura yung blue/yellow/pink foam?

So nagtaas agad ang price dahil lang sa color? Same lang naman yung density/material ng foam di ba?

Yes sir mas mura. Ang sabi sa kin flame retardant tong california grey and its normally used as acoustic foam. Di pang mattress.

For me ok lang mas mahal kasi mas ok yung color.  Too distracting yung pink, blue or yellow.

Ah ok. Baka iba pala ang material kaya mas mahal. Mas dense siguro ang material.

Same boat kame ni OP, problema ko rin yung kapitbahay ko sa baba.
Sa LF kasi yumayanig yung apartment, pero hindi naman masyadong rinig yung mids and highs especially kapag sealed pati pinto ng terrace namen.

Dito pa naman, drywall ang mga dingding kaya mahirap i-insulate sa sound.

Hindi na tuloy ako makabili ng sub, sabi ni wifey kapag nagkabahay na lang daw kame.

Nakaka 2 noise complaint nako from the landlady eh, ayoko nang buminggo.

carpet + subdude or gramma would help in your case.

I forgot to say that carpeted po ang whole floor area ng apartment namen, save the washroom.
I will try the subdude. Meron ba nyan for tower speakers?

yup subdude for towers pwede (unless youre using focals utopia kailangan mo 2x great gramma each tower )

There is a lot of misinformation in this forum about soundproofing. It is very different from what we perceive as acoustic treatment. Putting egg cartons acoustic foam, panels and bass traps will not solve your problem.  the idea about soundproofing is how you could isolate the sound inside from coming out or the other way around. The best soundproofing is based on construction techniques on how sound vibrations from going out(as in your case). soundproofing is as effective as your weakest link. Most of the time the door is the culprit. You have to have a heavy door with a lot of mass which means the thicker the better. It should also have some sort of weatherproofing so that the sound will not get through the seams especially under the door. a double door configuration, like those used in cinemas will do wonders because the sound attenuated by one door, say a reduction of 30dB will again be reduced by 30dB by the other door. The unit of measure that they use in soundproofing is STC (sound transmission coefficient). A thick 8 inch concrete wall might have a Stc of 55 dB which means if the maximum loudness in your home theater is around 105 dB then that wall will reduce it to 50 dB ( which is already tolerable for your neighbors). As I have said, it is the weakest link that matters. Heavy doors have a reduction of around 35 dB, so the outside sound will still be 70 dB. still quite loud. We are only talking about published STC figures from 125 hertz to 4000 hertz, low frequency is much more difficult to deal with.(subwoofer) even with a Stc of 55 dB for thick walls, it might just have a low frequency Stc of 15 dB, which means at maximum home theater level of 105 dB, outside it is still 90 dB and that is loud.

A small hole, an open window will be your weakest link. sound will go out even the hole is just 1 cm. in diameter. that is how soundproofing is so difficult to solve.

The cheapest way is really to make friends with your neighbor and invite them for a home cinema experience.

Soundproofing can be done, but it is very expensive to do it right. Special materials like resilient channels, double pane glass, metal doors and viscous damping material are just some of those used by pros.

Di pala sound proofing ang goal ko... hehe
Its acoustic treatment, i'm trying to reduce yung unwanted reflections.
