<P>PROBLEM TO BE SOLVED: To provide a sound absorption panel which has a solar cell and can be easily formed into various sizes, and to provide a soundproof wall formed by installation thereof. <P>SOLUTION: A front plate 21 having a number of apertures 21a is arranged on a front side, a back plate 22 is arranged on a rear side, and a sound absorption material is packed between the back plate 22 and the front plate 21 to form a panel shaped acoustic plate part. A solar cell panel 3 is arranged at the back of the acoustic plate part, projecting from the back plate 22 in the rear direction. A back face cover part 62 is arranged at each of the both lateral sides of the solar cell panel 3, projecting from the back plate 22 in the rear direction. The solar cell panel 3 having a shorter size than any length of the acoustic plate part is arranged and the back face cover part 62 is attached to the side of the solar cell panel corresponding to the length of the acoustic plate part, so that a sound absorption panel 1 having any length can be easily formed without processing due to a change in size of the solar cell. <P>COPYRIGHT: (C)2012,JPO&INPIT |
