It's better you tell us what your application is. like you want to stuff it in your ears or you need DIY insulation for your room?

比如屋内有宠物但是怕它吵到楼上
又或者经常要音乐，而且越大声越好，但是又怕吵到楼上

I think you are referring to "Audiophile's 吸音棉".  It is used for enhancing audio performance. It does not necessary absorb the sound from disturbing your  neighbor above.

Sound barrier is an expensive thing.  You can try suspended ceiling, it may help a little.

If it does not work, you have to insulated the ceiling with sound proof insulation like Roxul (Homedepot or other stores) with  thicker dry wall.

In any case, no easy fix in my opinion.

我要能removable 的stuff，因为我是租屋，不想把别人的房子改造

做果陣 你同你條仔
一人一條毛巾
咬住佢 咪嗌唔出声囉

重有
吸音棉
唔會將音浪減低
只係減少反弹
聽得清楚D啫
嗌D声重清晰
分得出係你嗌 定係你條仔嗌

An inexpensive, but effective solution:  There is something you can buy to seal off the gaps between your doors.  I think he buys those from Home Depot?   I am e-mail him this thread, and see he has time to tell you more!

- google up "sound proofing" and there will be lots of info about ways to reduce sound transmission to your neighbor.  
Basic idea:  Add mass, decoupling between inside and outside wall.
- If you're renting, there's nothing BIG you can do.  You can improve by fixing the weakest links:  Better window seals, put weather strips around your door so that it's air tight.  Add very heavy drapery to window/door will help a bit.

For better acoustics inside. (eg. for listening to music, or reducing the echoing/resonance), you can:
- Use carpet if you have a hard surface (helps with mid & high freq)
- Treat walls/ceilings with some form of absoprtion material (studio foam, heavy curtain)
- For low-freq stuff, you need bass traps, google it up.

Hope that helps, you're probably disappointed at the answers though.
