Test Arrangement 測試安排

 

Impact Sound Pressure (Ln) / Impact Insulation Class (IIC) is given by:

撞擊聲壓級計算方法如下:

Ln or IIC  = L + 10 log (A/A0)

A standard tapping machine is placed in operation on a test specimen that forms a horizontal separation between two rooms, one directly above the other.

The transmitted impact sound characterized by the spectrum of the space-time average one-third octave band sound pressure levels projected by the tapping machine is measured in the receiving room below.

Reverberation time inside the receiving room is also measured for room absorption correction.

測試件安裝在聲源室與接收室之間的洞口內,開動放於測試件上的標準撞擊器, 聲音經由測試件進入接收室內。

傳聲器於接收室中進行收音。

量度接收室的混響時間作為吸音量的修正用途。

Reduction of Impact Sound Pressure Level (rL) / Improvement in Impact Insulation Class due to floor covering (rIIC) is given by:

撞擊聲壓級改善量計算方法如下:

rL or rIIC  = L0 - Ln

Sound pressure levels inside the receiving room are captured under TWO situations:

1)       L0, Bare floor (NO floor covering),

2)       Ln, With floor coverings (e.g. carpet.)

在以下情況下進行撞擊測試:

1)          L0, 實驗室樓板

2)          Ln, 安裝測試件後

測試件的撞擊聲壓級改善量是以上兩者之差數。

Certify Your Buildings Specimen 為產品認證

 

Once finished laboratory measurement, a detail report of the measurement, and a Certification that certified the Impact Insulation Class (IIC / FIIC), Weighted normalized impact sound pressure (Ln,w / Ln’w), Reduction of impact sound pressure level (rL) or Improvement in Impact Insulation Class due to floor covering (rIIC) of the tested buildings specimen will be issued. People can refer to this Certification to consult the acoustics performance of your building products. No more estimation, true data is here.

 

所有的測試件於完成測試後, 均會發出一份具有公信力的測試報告以表示其隔音性能,客戶可以更了解產品的特性。
