바닥충격음의 주관적 평가 및 생활감과의 대응

Abstract

Floor impact noises in apartment buildings have been investigated as they are most annoying among the noises in living environment. Several experiments were undertaken to compare perceived noisiness of floor impact noises generated by bang and tapping machine along with children's jumping and running. Results show that bang noise is louder and noisier than tapping noise by 5-7dB. It was also found that the perceptual limits of the machine noises can be evaluated from L45 to L60 as was indicated by the Architectural Institute of Japan. It seems that the floor impact noise generated by children's jumping and running corresponds well with the machine noise.
