濟南汽車音響改裝http://www.szanyuda.com/談到大家由于對噪聲控制的手段缺乏了解，“吸音”和“隔音”常常被混淆了。下面濟南孚卡悅聽汽車音響改裝的專家就給大家詳細闡述一下這兩個概念的不同之處。
Jinan car audio conversion tool comes to us because of the lack of understanding of noise control, "acoustic" and "noise" is often confused. Jinan Fu Yue card below modified car stereo to listen to experts give you elaborate on the differences between these two concepts at.

濟南汽車音響改裝介紹吸音材料和隔音材料的區別在于，吸音材料著眼于聲源一側反射聲能的大小，目標是反射聲能要小。隔音材料著眼于入射聲源另一側的透射聲能的大小，目標是透射聲能要小。吸音材料對入射聲能的衰減吸收，一般只有十分之幾。因此其吸音能力即聲耗系數可以用小數表示；而隔音材料可使透射聲能衰減到入射聲能的3/10～4/10或更小，為方便表達，其隔聲量用分貝的計量方法表示。
Jinan car audio conversion describes the differences between sound-absorbing materials and insulation materials that focus on the size of the sound absorbing material source side of the reflected sound energy, the goal is reflected

sound can be small. Insulation materials focusing on the other side of the sound source is incident acoustic energy transmission size, the transmission of acoustic energy to the target is small. Sound-absorbing materials on the attenuation of incident sound energy absorbed, usually only a few tenths. So its sound absorbing capacity consumption coefficient that can be expressed as a decimal; and insulation materials enables the transmission of sound energy to

incident sound energy attenuation 3/10 1-4 / 10 or less, to facilitate the expression of its measurement methods decibels of sound insulation representation.

濟南汽車音響改裝提醒對于隔音材料要減弱透射聲能，阻擋聲音的傳播，就不能如同吸聲材料那樣多孔、疏松、透氣；相反它的材質應該是重而密實的，如鉛板、鋼板等一類材料。隔音材料材質的要求是密實無孔隙或縫隙，有較大的重量。由于這類隔聲材料密實，難于吸收和透過聲能而反射能強，所以它的吸聲性能差。
Jinan car audio conversion reminder for soundproofing materials to be reduced transmission of acoustic energy, stop the spread of the sound, it is not as porous as sound-absorbing material, loose, breathable; on the contrary it should be heavy and dense materials, such as lead, steel and other one class materials. Insulation material is dense material requirements without pores or slits, a greater weight. Since this type of insulation material is dense and difficult to absorb through the reflected sound energy can be strong, so the difference between its sound absorption performance.

濟南汽車音響改裝介紹在汽車噪音處理上，吸音和隔音所解決的目標和側重點不同，吸音所解決的目標是減弱汽車噪音在駕駛室內的反復反射，也即減弱駕駛的混響聲，縮短混響聲的延續時間即混響時間；在汽車行駛過程中連續噪音的情況下，這種減弱表現為室內噪聲級的降低。但由于吸音材料不可能裸露在汽車駕駛室內（有內飾板），內飾板會大量把汽車噪音直接反射，從而使吸音效果大幅度降低，所以吸音在降低汽車噪音的環節中，所占比重是最小的，效果也是最不明顯的；最有效的吸音部位是在汽車的引擎倉，正確的使用吸音材料可以大幅度的降低汽車發動倉的共鳴噪音！
Jinan car audio conversion introduces noise in the car handling, objectives and focus sound absorption and sound insulation addressed different acoustic goal is to weaken the resolve of the car noise is repeatedly reflected in the cab, that reduced driving reverberant shorten reverberant the duration of that reverberation time; in the case of cars with the process of continuous noise, which weakened the performance to reduce interior noise levels. But could not because of sound-absorbing material exposed in the car cab (with trim plate), interior panels will be a lot of noise direct reflection of the car, allowing a significant reduction in sound-absorbing effect, so the sound-absorbing part in reducing vehicle noise, the proportion of is minimal, the effect is most obvious; the most effective sound-absorbing parts in the automotive engine compartment, the correct use of sound-absorbing materials can greatly reduce car launch warehouse resonance noise!

濟南汽車音響改裝http://www.szanyuda.com/總結說利用隔音材料隔絕汽車噪聲的效果比采用吸音材料的降低汽車噪音效果要好得多。吸音和隔音有著本質上的區別，有效降低汽車噪音，一定要從概念上將減振材料、隔音材料、吸音材料正確區別開來。
Jinan car audio conversion concluded that the use of isolated car noise deadening effect than the use of sound-absorbing material to reduce vehicle noise effect is much better. Sound-absorbing and sound fundamentally different, and effectively reduce vehicle noise, vibration conceptually from certain materials, insulation materials, sound-absorbing material properly distinguished.
