Description

ここにおいて、係数ｂは、上述したとおり、探索期間において特定した反射音の音圧レベルに対する直接音の音圧レベルの比率である。すなわち、係数ｂは、聴取者の実際の再生環境に応じて変化する値であり、１＜ｂを満たす。一方、係数ａは、同様の比率を基準の再生環境において求めた値であり、基準の再生環境における反射音の最大音圧レベルに対する直接音の音圧レベルの比率を表すものである。係数ａは、基準の再生環境においてテスト音を実際に発生させ、これを収音した測定音を解析することによって求められてもよいが、シミュレーション等によって得られる音圧レベルの想定値によって決められていてもよい。係数ａは、１＜ａを満たす値である。
