This paper reports the rattling thresholds of windows or doors caused by ground vibrations. The frequency characteristics of the threshold curves by vertical and horizontal vibration were measured. The threshold for horizontal vibration is lower than

Psychological responses and permissible limits of 20 subjects under intermittent rattling noise of a fitting were measured. A subject sits in front of the fitting with glass plates and answers questionnaires for psychological state in/after exposure

In Japan there are two kinds of low frequency noise (LFN) problems. One is LFN that can be heard directly in a house and causes discomfort, and the other is LFN that rattles windows or doors and causes annoyance. Authors met about 100 complainants on

A porous elastic road surface (PERS) is superior to drainage asphalt pavement for reducing highway traffic noise. In earlier research and development, for example using a test track, the difference in sound power level (Lw) of cars has been regarded

In this report, we analyze the relationship between noise reduction and the thickness and aggregate size of the drainage asphalt road surface. Earlier results indicated overall noise reductions of 3–5 dB. However, noise reductions of 5–10 dB are

We extend our earlier work on developing a low-noise pavement by considering a porous elastic road surface (PERS). We find that the noise characteristics of PERS are superior to those of a drainage asphalt pavement including the normal absorption coe

In this report, we analyze the noise reduction observed in low noise drainage asphalt pavement. Earlier results have indicated overall noise reductions of 3–5 dB, but there has been some discrepancy as to whether this improvement is due to the high
