.01,sound insulation of doors and windows
In the house facing the street, 90% of the external noise comes in through the window. The key to sound insulation of windows lies in windows and laminated glass. The better the air tightness, the better the sound insulation effect. Ordinary hollow glass windows can play a certain sound insulation effect. The view that laminated glass has better sound insulation effect is not credible. Living in a crowded place near the city square, you can choose insulating glass to isolate medium and high frequency noise. There are many waiting areas near the main road, so it is necessary to isolate low-frequency noise with laminated glass.
Next, the window of plastic steel profile has the best sound insulation, but it is very easy to move down and deform, which is not as good as the insulation and durability of broken bridge aluminum. In addition, the way of opening the window will also endanger the sound insulation effect. Horizontal windows have stronger sound insulation effect than movable windows and inner windows. Due to structural shortcomings, the movable window and the inner window are not very airtight, so the sound insulation effect is much worse. In short, the key to sound insulation of windows depends on the overall material collocation. The text box of broken aluminum doors and windows+insulating glass+casement window can meet the sound insulation requirements of ordinary families.
In addition to windows, how to choose indoor wooden doors is also very important.
Look at the net weight The sound insulation effect of doors with light material and relatively low density is generally poor. Sound insulation effect of door leaf raw materials: solid wood board >; Composite solid wood floor > door core of under-bridge structure >: honeycomb paperboard. Tablet computers also have hollowed-out doors with sound insulation cotton in the middle, which is also good for sound insulation. Second, look at the thickness. The thickness of the door should be above 50mm, which can play a certain sound insulation effect. The satisfactory thickness of the door is between 50mm, and third, the sealing level of housekeeping. Generally, the installed door will be slightly folded or bulged. If the gap is too big, you can stick a circle of door frames to reduce it.
Sound insulation effect of different door opening methods: sliding door > horizontal door > horizontal door > railing door > warehouse door.
.02, roof, wall sound insulation
We are not afraid of the noise in the public place next door, but we can report it. But from the next-door neighbor, the low-frequency noise with no fixed time and little sound is very harmful to the brain. The children run and jump for a while, and then the screams of killing pigs, the shaking of the washing machine, the creaking of the bed, and the banging of falling objects are all crazy tests on the verge of your collapse.
If you want to do sound insulation for walls and roofs, you must think about whether you need to give up height and indoor area. Thin wall is the root cause of poor sound insulation, and there is no particularly good method. The key is to fill the wall with sound insulation cotton, stick sound insulation felt, seal gypsum board, and add sound absorption board if you want more effects. Then the double floor comes out, and the top is lowered by at least 20 cm, as are the walls. In fact, making a closet with a ceiling along the wall is the most space-saving scheme. Improve the thickness of the wall and can also be used for storage and finishing, killing two birds with one stone.
