It's very noticible when revving hard and no drone on cruising. I don't own a decimeter. To me, the Active Sound was like having an exhaust leak in the cabin. ANYTHING that keeps the noise on the OUTSIDE is an improvement. I don't care how loud the engine and exhaust are (I run modified exhausts in both my Porsches, for instance) but the key is WHERE the noise comes from.
