Dense population on a limited land, with the growth of population of metropolis, modern building structures now develop into high elevation gradually in Taiwan. To reduce the weight of construction itself, (Brick or RC Wall already does not fit for this construction category) Light steel frame partition wall provide with merit features of endure moist, light weight, fast construction, neat and tidy, durable and fireproof . Light Steel Frame Partition Wall has been implemented of great quantity in varies different constructions. Theoretically, because the lighter weight of itself, the soundproof characters could be inferior to traditional Brick Wall and RC Wall. This research is focused on the sound proof parameters of the constitution of light steel frame partition wall. This research is also focus on the Silicon Calcium board light steel frame partition wall. Research is performed in meet standard requirement laboratory and measured by precision instrument, by use Acoustic Strength measurement to probe into the influence factor of filler substance, steel frame distance, screw distance etc. This research is dedicated to provide these parameters as a reference for future related design.
