一：作為窗戶的隔（gé）音對策，通常（cháng）是采用雙層窗的結構。可以把現有的窗戶（hù）保留（liú），再追加一扇窗戶;或者是去掉已有（yǒu）的窗戶，重新安裝一扇按新標準設計的（de）玻璃都一樣厚，它們（men）的諧振頻率就是相同的。這樣會使該頻率附近的聲音很突出。一（yī）般情況下，兩層窗戶的間（jiān）隔應有20cm-30cm。要達到和混凝土牆同樣的-50dB的（de）隔音效果，比較好兩（liǎng）層玻璃（lí）之間的間隔在30cm以上。如能（néng）在此間隔中再采取一（yī）些吸音措施，那就更好了。正確地施工，房間能保證-50dB的隔音特性。

　　二：第（dì）二個薄弱（ruò）環節就是（shì）門。隔音效果比較差的要（yào）數一般集體公寓中（zhōng）和簡單家庭裝修中裝設的門（mén），粗（cū）造地用膠合板釘的門和門（mén）框之間有不（bú）小的間隙，其隔（gé）音特（tè）性比較多不過-15dB。一般住宅門的隔（gé）音（yīn）特性可達-25dB~-35dB。性能更高的，監聽室（shì）用的那種鐵門很（hěn）少在民宅中（zhōng）見到。現在（zài）日（rì）益增多的雙層防盜門有不錯的隔音（yīn）特性。

　　三：接（jiē）下（xià）來的工作是對各種（zhǒng）牆壁隔音（yīn）特性的增（zēng）強。一般民宅的承重牆用鋼（gāng）盤混凝土或（huò）實心磚的結構，有較好的隔音效（xiào）果。問題多出在隔牆采用的輕（qīng）型空心磚或（huò）灰膠紙板，隔音特（tè）性隻（zhī）有-25dB~-30dB。多數家庭影院（yuàn）的房間都有（yǒu）一至二堵牆麵是這樣的結構。毫無疑（yí）問，除了窗戶和門之外，這是產生聲音匯漏（lòu）比較為嚴重地方。如（rú）不采取措施，空心磚中間的空氣振動會（huì）引起（qǐ）牆壁共振（zhèn），這種情形對音（yīn）質十分不利。具體解決的辦法有兩種。一（yī）是拆掉原（yuán）有牆壁，重新打造一堵隔音牆;二是保（bǎo）留原有的牆壁，增加一（yī）堵隔音牆。

　　四：要作到真正的隔音，自然是對房（fáng）間的六個麵實施隔音措施。如果隻對相（xiàng）鄰（lín）房間的牆壁（bì）(隔牆)增加（jiā）一定的隔音性能，那麽，地（dì）麵和天花板（bǎn）對聲音的影響又（yòu）會（huì）突出來。為了防止這種情況的出現，完全切底的隔音肯定是對房間的六個麵都采取相應的措施（shī）。要更好地（dì）提高（gāo）房間的隔音特性，就（jiù）是在房間中再造一個房間，即所謂“室中室”的結構。

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.
