Semi-anechoic Chamber Project of the Malaysia Super Factory of Alton Intelligent Technology Sdn.Bhd. in Malaysia

一、项目介绍

 I. Project Introduction

欧圣电气股份有限公司由美国欧圣工业集团投资建设，是国内综合优势领先的空气动力设备和清洁设备制造商之一。欧圣马来西亚超级工厂位于马来西亚柔佛州，其中包含大型厂房和实验楼、办公楼、食堂、宿舍以及员工活动中心等建筑，欧圣坚持以“公平公正、共治共享”为核心发展理念，注重人才，打造企业核心竞争力。欧圣电气股份有限公司向我司采购声学实验室项目。

Invested and built by United States Alton Industrial Group,Alton Intelligent Technology SDN.BHD. is one of the leading manufacturers of air power equipment and cleaning equipment in China. Located in Johor, Malaysia, including large factories and laboratory buildings, office buildings, canteens, dormitories and employee activity centers,Alton Intelligent Technology SDN.BHD. MALAYSIA 

MEGA  Factory adheres to the core development concept of "fairness and justice, co-governance and sharing", pays attention to talents and builds the core competitiveness of enterprises.

由广州丹品人工环境技术有限公司设计及承担建设该声学实验室项目，并在规定的时间内竣工且通过验收。产品竣工验收合格后，继续承担质量保证、保修、维修和技术支持的责任。安装地点为需方工业区内。

The acoustic laboratory project was designed and constructed by GZ DP Anechoic T&E Co., Ltd. It was completed within the specified time and passed the acceptance inspection. After the product passed the completion acceptance inspection, the company continued to assume responsibilities for quality assurance, warranty, repair, and technical support. The installation location is within the industrial zone of the buyer.

二、项目要求

II. Project Requirements

产品项目内容：

Product Project Details:
本次声学实验室是精密级半消声室，项目建设方案及使用材料全部由我司负责设计安装，我司应将其“涡轮增压微循环变频消声通风”（专利号：200520108948.5）的全部或部分应用于声学实验室的安装项目项目建设之中；

This acoustic laboratory is a precision - grade semi - anechoic chamber. Our company is responsible for the design and installation of the project construction plan and the materials used. Our company should apply all or part of its "Turbocharged Micro - circulation Frequency - conversion Muffling Ventilation" (Patent No.: 200520108948.5) to the installation project of the acoustic laboratory.

1）精密级半消声室安装项目内部的有效净尺寸：7.3 mx5.4mx3.0 m；

The effective internal net dimensions of the precision - grade semi - anechoic chamber installation project: 7.3 m×5.4 m×3.0 m.

2）人员通行门尺寸：W×H＝1.4×2.0（m）

The size of the personnel passage door: W×H = 1.4×2.0 (m)

半消声室主要验收条款：

Main Acceptance Clauses for the Semi - anechoic Chamber

当外部环境噪声：Len（A）≤65dB（A），周围无异常干扰（如砸 地、打桩、冲击)且空调通风系统关闭，仅灯具开启时，半消声室室内本底噪声 : Lgn(A)≤20dB（A）；截止频率：Fc≤100Hz。

When the external environmental noise: Len(A) ≤ 65dB(A), there is no abnormal interference around (such as ground - pounding, piling, impact), and the air - conditioning and ventilation system is turned off while only the lamps are on, the background noise inside the semi - anechoic chamber: Lgn(A) ≤ 20dB(A); Cut - off frequency: Fc ≤ 100Hz.

三、声学设计

III. Acoustic Design
1、隔声设计实现本底噪声指标
