In this paper, the acoustic impedance of a liner is educed by a novel semi-analytical inverse technique. The liner sample is placed flush with the solid walls in a rectangular duct with grazing flow. The technique uses complex acoustic pressure measured at four positions at the wall of the duct, upstream and downstream of the lined section, and edu

So much has changed. When you get older, you look back on tensions and grievances and have another perspective on it. I think our relationship now is better than it's ever been.
