This configuration prevents rainwater that has entered the noise inflow hole 171 during rainy weather from being directly absorbed by the sound absorbing material 172 by the inclined section 171a, and the noise that has entered the noise inflow hole 171 is inclined section (171a). ), So that the primary sound insulation effect can also be obtained.

상기 경사절편(171a)은 진입된 소음을 상/하방향으로 안내할 수 있도록 일부는 상방향으로 절곡하고 일부는 하방향으로 절곡 형성시킬 수 있다.The inclined section 171a may be bent partially upward and partially bent downward to guide the entered noise upward / downward.

한편, 본 발명의 또 다른 예의 방음패널을 나타낸 도 5를 참조하면, 이는 상기 개구홀(101)의 최저 지점(A)에 대응되는 높이에서 상기 흡음재(172)에 우수차단판(175)이 삽입된 것이다.On the other hand, referring to Figure 5 showing a soundproof panel of another example of the present invention, it is inserted into the excellent blocking plate 175 in the sound absorbing material 172 at a height corresponding to the lowest point (A) of the opening hole 101 It is done.

이는 호우와 같이 많은 양의 비가 내릴경우 급속히 상기 상부중공부(160)와 하부중공부(161)에 수위가 높아질 경우에 대비하여서, 상기 흡음재(172)가 전체적으로 빗물이 침투되는 것을 방지한다.This prevents rainwater from penetrating the sound absorbing material 172 as a whole, in case the water level increases in the upper hollow portion 160 and the lower hollow portion 161 rapidly when a large amount of rain falls like a heavy rain.
