摘要
声学实验室是声学专业的测试实验室,它在音视频产品的声学性能检测和电子电器产品的噪声声功率级测量中得到广泛的应用。声学实验室由消音室和声学测试系统构成,要分别做好消音室的设计和声学测试系统的设计。从设计和建设声学实验室的角度出发,详尽阐述了声学测试标准、消音室的设计指标以及核心构成、关键技术指标,以及配套声学测试系统的组成。为声学实验室设计者和使用者提供科学的参考依据。
The acoustic laboratory is a testing laboratory specialized in acoustics,which is widely used in the acoustic performance testing of audio and video products and the measurement of noise power levels in electrical products.The acoustic laboratory consists of a anechoic chamber and an acoustic testing system,and the design of the anechoic chamber and the acoustic testing system should be done separately.From the perspective of designing and constructing an acoustic laboratory,this paper elaborates in detail on the acoustic testing standards,design indicators and core components of the anechoic chamber,key technical indicators,and the composition of the supporting acoustic testing system.Provide scientific reference basis for acoustic laboratory designers and users.
