Method for controlling sound absorbing characteristic of soundproof material |
| abstract |
The present invention addresses the problem of providing a method for controlling the sound absorbing characteristic of a soundproof material capable of changing the sound absorbing characteristic of the soundproof material while maintaining, at the same amounts, the constituent material, the total thickness, and the total weight of the soundproof material. The solution means for the problem is the method for controlling the sound absorbing characteristic of a soundproof material which is provided with: a skin layer composed of a fibrous material; a rear surface layer laminated on the skin layer and composed of a porous material having voids communicating with each other; and a joining layer that is composed of a joining material and is laminated between the skin layer and the rear surface layer, wherein a total joint area fraction with respect to the entire contact surface between the skin layer and the rear surface layer is less than 100%. The method for controlling the sound absorbing characteristic of a soundproof material controls the sound absorbing characteristic of the soundproof material by changing the area of the joining layer. |
