商业建材实验室声学测试服务

Acoustic testing service of Commercial construction Materials Laboratory

一、实验室介绍Lab introduction

SGS常州声学实验室由混响室、空气声隔声实验室和撞击声隔声实验室组成，可以提供材料吸音系数、各类门窗与墙体的空气声隔声性能以及楼板的撞击声隔声性能等测试。

SGS Changzhou Acoustics Laboratory, including reverberation chamber, sound insulation laboratory and impact sound insulation laboratory, has the capacity of sound absorption test for Sound-absorbing materials, sound insulation test for various doors, windows and walls, and impact sound insulation performance for floor, etc.

1、 混响室Reverberation Chamber

混响室采用“房中房”的隔声结构，具有独立的基础和隔振措施。围护结构厚实，内表面光滑，界面吸声系数很小，使室内基本满足扩散声场的条件。主要可用于测试吸声材料对无规则入射声波的吸声系数和声源（设备）的辐射功率，也可用于校准传声器、送话器的扩散声场灵敏度。

The reverberation chamber with independent foundation and isolating measures adopts the "room in the room" sound insulation structure. Thick enclosure structure, smooth inner surface and the small sound absorption coefficient make the chamber basically meet the diffusion sound field conditions. It can be used to measure the sound absorption performance of the irregular incident sound wave and the radiation power of sound source (equipment). It can also be used to calibrate the diffuse field sensitivity of microphone and transmitter.

2、 空气声隔声实验室Airborne Sound Insulation Laboratory

空气声隔声实验室是由左右两间体积较小的混响室组成，包括声源室和接收室，两室之间有10 m²的测试洞口，用于安装测试构件。声源室和接收室均采用“房中房”的隔声结构，有独立的基础和隔振措施，以消除侧向传声的不利影响，保证构件隔声性能的准确测量。主要用于测量隔声窗、隔声门、隔声墙等隔声构件的空气声隔声性能。

Airborne sound insulation laboratory is composed of two parallel small reverberation chambers, including sound source room and sound receiving room, there is a 10m² test opening between the two rooms for the installation of test sample. Both the sound source room and the sound receiving room with independent foundation and vibration isolation measures adopt the "room in the room" sound insulation structure to eliminate adverse effects of flanking transmission. It is mainly used to measure the airborne sound insulation performance of building products, such as sound insulation windows, doors, walls and other sound insulation component.

3、 撞击声隔声实验室Impact Sound Insulation Laboratory

撞击声隔声实验室是由上下两间较小的混响室组成，均采用“房中房”的隔声结构，具有独立的基础和隔振措施。中间的楼板开有10 m²左右的测试口，用于安装测试构件。主要用于测量隔声垫、减震垫、地板、地毯及各种铺地隔声减震材料等的撞击声隔声性能。

Impact sound insulation laboratory is composed of two vertical small reverberation chambers, the chambers with independent foundation and isolating measures adopts the "room in the room" sound insulation structure. There is a 10 m² test opening between the two chambers for the installation of test sample. It is mainly used to measure the impact sound insulation performance of sound insulation and damping materials, such as sound insulation pad, damping pad, floor and carpet.

二、测试介绍Test introduction

1、吸声性能测试Sound absorption measurement

测试将使您更好的了解各种材料的吸声特性，以便利用已知吸声特性的材料和结构，控制建筑物内的噪声，或者创造较为理想的声学环境。

Sound absorption measurement will enable you to better understand the sound absorption characteristics of various materials, so that you can use materials and structures with known sound absorption characteristics to control the noise in the building or create an ideal acoustic environment.

2、空气声隔声测试Airborne Sound Insulation Measurement

隔声测试会让你充分了解各类建筑构件的隔声性能，使用合适的隔声构件，在保证室内环境的私密性的同时，降低外界噪声对室内的影响。

The measurements will let you fully understand the sound insulation performance of various building components, so that you can use appropriate sound insulation components to ensure the privacy of the indoor environment while reducing the impact of external noise.

3、撞击声隔声测试Impact Sound Insulation Test

测试可以评估当楼板、楼板覆盖物和吊顶系统在受到上层固体物体撞击时对下层空间产生的撞击声影响。现实中商务楼宇和多层住宅中的休息空间对这一特性尤为看重。

The measurements can be used to evaluate the impact effect of floor, floor covering and ceiling system on the lower space when impacted by the upper solid objects. Impact sound insulation performance is particularly important for the rest space in commercial buildings and multi-storey houses in reality.
