Effect of spatial factors on subjective responses to heavy-weight floor impact noise
중량충격음의 주관적 반응에 대한 공간음향요소의 영향
Abstract
The effect of spatial factors on subjective responses to heavy-weight floor impact noise was investigated. Heavy-weight impact noises were generated and recorded in several apartments and a testing building using impact ball and binaural microphone to measure IACC of the noises. Just noticeable differences (JNDs) of IACC and SPL of heavy-weight impact noise were also investigated. Auditory experiments were conducted using method of limit. It was found that the JNDs of IACC and SPL were 0.12 and 1.5dB, respectively. Contribution of IACC and SPL to annoyance of heavy-weight floor impact noise is being further investigated.
