  一:作为窗户的隔音对策,通常是采用双层窗的结构。可以把现有的窗户保留,再追加一扇窗户;或者是去掉已有的窗户,重新安装一扇按新标准设计的玻璃都一样厚,它们的谐振频率就是相同的。这样会使该频率附近的声音很突出。一般情况下,两层窗户的间隔应有20cm-30cm。要达到和混凝土墙同样的-50dB的隔音效果,比较好两层玻璃之间的间隔在30cm以上。如能在此间隔中再采取一些吸音措施,那就更好了。正确地施工,房间能保证-50dB的隔音特性。

  二:第二个薄弱环节就是门。隔音效果比较差的要数一般集体公寓中和简单家庭装修中装设的门,粗造地用胶合板钉的门和门框之间有不小的间隙,其隔音特性比较多不过-15dB。一般住宅门的隔音特性可达-25dB~-35dB。性能更高的,监听室用的那种铁门很少在民宅中见到。现在日益增多的双层防盗门有不错的隔音特性。

  三:接下来的工作是对各种墙壁隔音特性的增强。一般民宅的承重墙用钢盘混凝土或实心砖的结构,有较好的隔音效果。问题多出在隔墙采用的轻型空心砖或灰胶纸板,隔音特性只有-25dB~-30dB。多数家庭影院的房间都有一至二堵墙面是这样的结构。毫无疑问,除了窗户和门之外,这是产生声音汇漏比较为严重地方。如不采取措施,空心砖中间的空气振动会引起墙壁共振,这种情形对音质十分不利。具体解决的办法有两种。一是拆掉原有墙壁,重新打造一堵隔音墙;二是保留原有的墙壁,增加一堵隔音墙。

  四:要作到真正的隔音,自然是对房间的六个面实施隔音措施。如果只对相邻房间的墙壁(隔墙)增加一定的隔音性能,那么,地面和天花板对声音的影响又会突出来。为了防止这种情况的出现,完全切底的隔音肯定是对房间的六个面都采取相应的措施。要更好地提高房间的隔音特性,就是在房间中再造一个房间,即所谓“室中室”的结构。

A: as a window of sound insulation countermeasures, is usually the use of double window structure. You can keep the existing window and add another window; Or you could take out the existing window and install a new one that's the same thickness and resonates at the same frequency. This will make sounds near that frequency stand out. Under normal circumstances, the interval between two floors of Windows should be 20cm-30cm. To achieve the same -50dB sound insulation effect as concrete walls, it is best to have more than 30cm between two layers of glass. If can take a few sound-absorbing measure again between here, that is better. Properly constructed, the room has a -50dB sound insulation characteristic.

Two: The second weak link is the door. Sound insulation effect is worst want the door that number general collective apartment and simple family are decorated in the outfit that set, there is not small gap between the door that rough ground uses plywood nail and doorcase, its sound insulation characteristic does not cross most -15dB. The sound insulation characteristics of general residential doors can reach -25dB~ -35DB. Higher performance, the kind of iron doors used in surveillance rooms are rarely seen in private homes. The double-deck door that increases day by day now guards against theft has pretty good sound insulation characteristic.

Three: the next work is to enhance the sound insulation characteristics of various walls. The load-bearing wall of general residential buildings is made of steel plate concrete or solid brick, which has better sound insulation effect. The problem is more light hollow brick or gray adhesive paper board used in the partition, sound insulation characteristics only -25dB~ -30DB. The room of most home cinema has one to 2 metope is such structure. Without a doubt, after Windows and doors, this is the place that produces the most leakage of sound. If do not take a measure, the air vibration among hollow brick can cause wall resonance, this kind of circumstance is very adverse to sound quality. There are two specific solutions. One is to tear down the original wall, to create a sound insulation wall; 2 it is to reserve original wall, add wall of a sound partition.

Four: want to make true sound insulation, it is to implement sound insulation measure to the 6 sides of the room naturally. If only on the adjacent room wall (partition) to increase a certain amount of sound insulation performance, then, the ground and ceiling on the impact of sound will be prominent. In order to prevent the occurrence of this situation, completely cut the bottom of the sound insulation is certainly to take corresponding measures on the six sides of the room. To better improve the sound insulation characteristics of the room, it is to recreate a room in the room, namely the so-called "room in room" structure.
