  "textContent": "Disclosed is a sound-absorbing body which has sound-absorbing characteristics suitable for use in home audio systems and car audio systems, wherein the indoor echo of sound wave output from a speaker should be reduced or echo in a speaker enclosure should be reduced, namely, showing flat sound-absorbing properties while maintaining a high sound-absorbing ratio in the medium tone range, and which has a simple structure, can be easily installed and made water-resistant and decorative and, therefore, is easily usable at home. Specifically disclosed is a sound-absorbing body comprising a plurality of porous members provided with air pores formed therein and a structure composed by three or more layers that is formed by bonding the individual porous members via an adhesive layer having a preset thickness, wherein one side of said structure is located on the side of a sound source and the other side of said structure has a peak-and-valley pattern that is formed by alternately positioning said porous members and air layers to thereby flatten and improve the sound-absorbing ratio in the medium tone range. Owing to this simple constitution, the sound-absorbing body can be easily installed and made water-resistant and decorative.",
