I think the price of the wooden keel and the metal keel for the partition wall is about the same, because now the soil erosion and the price of wood are rising, and the price of you brush the asphalt oil and 50 iron keels is about the same, and the iron keel spacing is 600, and then it is filled with rock wool to play the role of sound insulation and insulation.
This has this similar job skill set that you can talk about.
Make a secondary ceiling so that the surroundings don't look deep! A little suggestion.
Hehe, you really know a lot of digging, now the ceiling of ordinary home decoration is ordinary gypsum board The rest I don't know :) help you ask your colleagues again.
The vibration of the ceiling air-conditioning unit is mainly generated by the rotation of the fan, which is transmitted to the floor structure through the pipe and the support and hanger, and the floor slab is affected by its vibration disturbance and will also produce low-frequency secondary structure-borne noise. If multiple noises are superimposed on each other, which is 20 dB(A) higher than the outdoor noise of the same sound source, the air conditioning room should take corresponding noise reduction measures.
Well, that's a good genius idea, and it's a small space. Why don't we wrap the beams or decorate them with columns?? A curved top is also a good idea. >>>More
