| Abstract(J) | 自動車用ダブルフェルト型防音材において，吸音層フェルトとフィルム間の低バネ定数領域を制御することで透過損失（TL）を向上する技術を開発した．さらに，本技術を適用したダッシュインシュレーター試作品を作成し実車評価で効果を確認した． Translation |
| Abstract(E) | A technique for improving transmission loss (TL) in automotive double-felt soundproofing materials was developed by controlling the low spring constant region between the sound-absorbing felt and the film. Furthermore, a prototype dash insulator incorporating this technique was fabricated, and its effectiveness was validated through in-vehicle evaluation |
