A study on 7 color marking of impact noise

Abstract

Interlayer noise is a noise pollution that occurs mainly in a space where a large number of households, such as multi-family houses or apartments, are together. There are various types of interlayer noise depending on what kind of sound is generated, but there are impact sounds as a great stimulus to human auditory sense. However, to date, the issue of interlayer noise has been the subject of concern because the interlayer noise criterion limits the average size of a certain section and there is no standard for impact noise that appears temporarily. Therefore, in this paper, A7B shows the number of impulse sounds in a row in order to make objective visual data about the interlaminar impact noise. In this case, the criterion of the impact sound is defined as a portion where a large change in sound volume occurs within 0.1 second. Experimental results show that the results similar to the number of impact sounds of the corresponding interlaminar impact noise source can be visually confirmed, and furthermore, it is possible to present clear and objective data in the interstory noise dispute.
