Abstract

The invention relates to an intelligent laboratory measurement system for building component sound reduction index. The system mainly comprises an intelligent sound production module, a noise test module, an intelligent mobile terminal, a receiving chamber and a sound source chamber. The intelligent sound production module comprises an intelligent signal generator, a power amplifier all-in-one machine and a regular dodecahedron sound source. The noise test module comprises a support, an intelligent positioning device and an intelligent sound level meter. The intelligent mobile terminal comprises an intelligent positioning device control module, a sound source control module, a sound reduction index analysis module and a data display module. The noise test modules in the receiving chamber and the sound source chamber transmit data to the intelligent mobile terminal in a wireless manner, and the sound reduction index analysis module analyzes and processes the data to obtain the sound reduction index of each frequency band constructed by the tested building. According to the invention, a remote building component sound reduction index testing method can be realized, the human influence in the noise measurement process is reduced, and the obtained test data is more accurate, more credible and more authoritative.

Description

technical field [0001] The invention relates to a measurement system, in particular to an intelligent laboratory measurement system for the sound insulation of building components. Background technique [0002] With the continuous development of modern industry, environmental pollution has also emerged. As a kind of environmental pollution, noise pollution has become a major hazard to human society. Noise pollution, water pollution, air pollution, and solid waste pollution are known as four major environmental problems worldwide. [0003] In order to control the spread of noise, control measures such as noise elimination, sound absorption and sound insulation are taken on the noise transmission path, which can effectively eliminate or reduce noise pollution. Sound insulation has been widely used as an effective noise reduction method, such as sound insulation room, sound insulation cover, sound insulation screen and so on. In order to make an objective and quantitative eva...
