Claims (8)
- 自動車両内の妨害騒音を評価するための方法において、規定の測定時間中に発生する騒音が様々な周波数領域に分割されること、それらの周波数領域内で背景騒音に対するレベル変化が決定されること、及び、そのように検出されたレベル変化が評価されることを特徴とする方法。
- 騒音が、背景騒音を検出するために、それらの周波数領域内で第1時間窓を用いてスキャンされ、この時間窓を越えて平均化されることを特徴とする、請求項1に記載の方法。
- 第1時間窓が、周波数領域にとって、互いに同じ長さの継続時間のものであることを特徴とする、請求項2に記載の方法。
- 騒音が、非定常の騒音部分を検出するために、それらの周波数領域内で第2時間窓を用いてスキャンされ、これらの第2時間窓の継続時間が第1時間窓の継続時間よりも短いことを特徴とする、請求項1〜3のいずれか一項に記載の方法。
- より高い周波数の領域ための第2時間窓が、より低い周波数の領域のためのものよりも小さい時間長さを有しることを特徴とする、請求項4に記載の方法。
- レベル変化が頻度に関して評価され、この頻度を用い、非定常の騒音事象が非定常の騒音部分内で発生することを特徴とする、請求項1〜5のいずれか一項に記載の方法。
- レベル変化が振幅に関して評価され、この振幅を用い、非定常の騒音事象が非定常の騒音部分内で発生することを特徴とする、請求項6に記載の方法。
- レベル変化・頻度及びレベル変化・振幅の重み付きの成された合計が全周波数領域に渡って決定されることを特徴とする、請求項7に記載の方法。
