SOUND ABSORBING PANEL AND SOUNDPROOF WALL EQUIPMENT
Provided is a sound absorbing panel 1B provided further above an uppermost one of soundproof panels 1A arranged in plural stages in a vertical direction and each having a back surface opposite to a sound source side, the back surface being formed to be a sound insulating surface, in soundproof wall equipment having the soundproof panels 1A arranged in plural stages in the vertical direction, the sound absorbing panel 1B including: an outer frame body 12 having therein an acoustic space in which a first acoustic material 10 is provided, the outer frame body 12 allowing formation of a partition wall separating a sound source and an area around the sound source from each other, the outer frame body 12 having, at a sound-source-side front surface portion 13 and a back surface portion 14 thereof, sound transmitting surfaces each having multiple sound through holes 6 allowing transfer of sound between the acoustic space and outside thereof; and a second acoustic material 11 provided further above an upper end of the outer frame body 12 such that at least a peripheral surface of the second acoustic material 11 except for a corner portion of an upper end edge on a sound source side is air-permeable.
