ACTUAL SITUATION OF CORRELATION ABOUT FLOOR IMPACT SOUND INSULATION RATING

Abstract

Impact source be used in the rating of floor impact sound are the tapping machine and the tire. L grade is generally using single-number quantity. However, the ball was introduced for standard heavy weight impact source in JIS A 1418-2:2000, and single-number quantity by the A-weight floor impact sound level has been studied.
In this report, we compared each single-number quantity.
As a result, there is no correlation A-weight floor impact sound level using the boll and L grade using the tire.
