一（yī）：作為窗戶的隔音對策，通常是采用雙層窗的結構。可以把現有的（de）窗戶保留，再追加一扇窗戶（hù）;或者（zhě）是（shì）去掉已有的（de）窗戶，重新安裝一扇按新標準設計的（de）玻璃都（dōu）一樣厚，它們的諧振頻率就是相同的。這樣會使該（gāi）頻（pín）率附近的聲音很突出（chū）。一般情況下，兩層窗戶的間隔應有20cm-30cm。要達到和混凝土牆同樣的-50dB的（de）隔音效果（guǒ），比較好兩層（céng）玻璃之間的間隔在30cm以上。如（rú）能在（zài）此間隔（gé）中再采取一些（xiē）吸（xī）音措施，那就更好了（le）。正確地（dì）施工，房間能保證-50dB的隔音特性。

　　二：第二個薄弱環節就是（shì）門。隔音（yīn）效果比較（jiào）差的要數一般集體公寓中和簡單家庭裝修中裝設的門，粗造地用（yòng）膠合板釘（dìng）的門和門框之間有不小的間隙，其隔音特性比較（jiào）多不過（guò）-15dB。一般（bān）住宅門的隔音特性可達-25dB~-35dB。性能（néng）更高的，監聽室用的那種鐵門很少在民宅中見到。現在日益增多的雙層防盜門有不錯的隔音特性。

　　三：接（jiē）下來的（de）工作是對各種牆壁隔音特性的增強。一般民宅的承重牆（qiáng）用鋼盤混凝（níng）土或實心磚的結構，有較好的隔音效果。問題多出在隔牆采用的輕型空心磚或（huò）灰膠紙板，隔音特性隻有-25dB~-30dB。多數家庭影院的房間都有一至二堵（dǔ）牆麵是這樣的（de）結（jié）構（gòu）。毫無疑問，除了窗戶和門之外，這是產生聲音匯漏比較為嚴重地方。如不采（cǎi）取措施，空（kōng）心磚中間的空氣振（zhèn）動會引起牆壁共振，這種情形（xíng）對音質十分不利。具體解（jiě）決的辦法有（yǒu）兩種。一是拆掉原有牆壁，重新打（dǎ）造一堵隔音牆;二是保留原有的（de）牆壁，增加一堵隔音牆（qiáng）。

　　四：要作到真正的隔音，自然（rán）是對房間的六個麵實施隔（gé）音措施。如果隻對相鄰房間的牆壁(隔牆)增加（jiā）一定的隔音性（xìng）能，那（nà）麽，地麵和天花板對聲音的影響又會突出來。為了防止這種情況的出現，完全（quán）切底的隔（gé）音肯（kěn）定是對房間的六個麵（miàn）都采取相應（yīng）的措施。要更好地（dì）提高房間的隔音特性，就是（shì）在房間中再造（zào）一個房間，即所謂“室中室”的（de）結構。

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.
