Abstract：According to the traditional sound insulation measurement method of building elements, an sound insulation intelligent laboratory measurement system based on the internet of things was developed. By using of wireless measurement scheme, reducing the use of measurement equipment, developing intelligent mobile terminal measurement control software to meet the requirements of automatic and accurate measurement of sound insulation of building components, which made the sound insulation measurement more intelligent and convenient. The experimental measurement results show that the measuring equipment and system meet the requirements of JJF 1789—2020《Calibration specification for sound insulation measurement room》 and GB/T 19889.3—2005 《Acoustics-measurement of sound insulation in buildings and of building elements-Part 3》, which can realize accurate and rapid measurement of sound insulation of building elements, and the measurement efficiency is also improved about one time, the optimal uncertainty of the sound insulation is 1.0dB.
