Sound Transmission Loss Test System Of Industry And Civil Architecture Glass For Experiment Study

Nowadays, the sound transmission loss of architecture glass is brought out as a new guideline of architecture glass design, but domestic architecture glass sound transmission loss experiment depends on abroad test institution absolutely. More and more domestic scholar and architecture industry pay attention to how to break architecture glass technology monopolization and build up domestic the test system. The architecture glass domestic test system owns bright practical foreground.The paper is to do research about according to the measure standard requirement of North American, having designed and builded the acoustics laboratory, making up test system with domestic typeⅡacoustics test device, By using VA--Lab, acoustics data collection analysis software, sound transmission loss test research is done to target plate (leading) and 4mm steel glass mainly in central frequency of 400Hz～8000Hz 1/3 octave frequency. From two aspects, one is to do sound transmission loss test to target plate (leading), comparing with its theory calculation value then calculate system calibrated data, another one is to do sound transmission loss test to 4mm steel glass, comparing with the standard value which is recommended by North American glass society and the test value which is got from typeⅠacoustics device by General Motor in American. Then comparing the different value with the allowed different value of glass sound transmission loss test standard of North American Specification. At last, the paper analyses the rationality and practicability of typeⅡdevice testing system in architecture glass sound transmission loss test.In conclusion, there is certain guiding significance to know the test precision of typeⅡacoustics device testing system, realistic significance of typeⅡacoustics device testing system's applicability, and the conclusion could provide certain scientific evidence and technological support for domestic glass manufacture company.
