Replying to: wwest (Jul 09, 2008 7:31 am) Possibly but I don't think we've actually established whether the "sound" is infrasonic and more input from the OP would be helpful. It could just be audible low frequency sound. In any case, it's probably just the ubiquitous "helicopter" effect with sound being produces with pressure changes occurring at the window opening. tidester, host SUVs and Smart Shopper
