An Experimental Study on Evaluation of the Sound Insulation for Balcony Window in Apartment Houses

In an apartment house In Korea, the balcony is one of the important spaces as a buffer zone for controlling the outdoor environments such as noise, heating & cooling load, humidity etc. Because most areas of building facade in apartment building occupy the area of balcony window the sound Insulation design of It Is very Important to provide the quiet indoor environment. The aim of this research is to evaluate the sound insulation of balcony windows in apartment building by new and revised Korean Industrial Standards. We measured and studied the sound insulations of 18 balcony windows by the type of measuring methods, noise sources, correction of reverberation time in balcony and so on. The results show that the single-number quantities for sound insulation of windows are ranged from 24 dB to 30 dB.
