  • Estimation of the insertion loss of the detached houses on railway noise

抄録

<p>In this paper, in order to study the effect of excess attenuation of railway noise due to detached houses, the two methods to evaluate single event sound exposure level (SEL) are examined. One is SEL estimated by using the maximum sound pressure level from Shinkansen trains, the other is SEL obtained by integrating the sound pressure level during a train pass-by. It is found that there is difference between two SELs and that linear relationship between the difference and the grazing angle φ or building area ratio γ can be seen in some cases.</p>
