<p><P>PROBLEM TO BE SOLVED: To provide a soundproof panel and a soundproof wall, which further enhance soundproof effect for an entire sound range including a low frequency range from 100 Hz to 300 Hz. <P>SOLUTION: A soundproof panel 14 comprises a sawtooth component 16 formed of a rigid material with a sawtooth-shaped edge formed from a combination of vertical sides extending in vertical direction and oblique sides tilting from the vertical direction, and at least one sound absorption component 18 which is arranged at least through a path of sound waves propagating between the neighboring teeth of the sawtooth component 16 and allows a part of incident sound waves to be attenuated and the remainder to be transmitted. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
