Active control of acoustic radiation from a "semi-infinite" beam clamped at one end is studied experimentally. The beam is excited by subsonic flexural travelling waves which "scatter" (or produce reflected travelling and near-field waves) when they encounter the clamped discontinuity. The main purp
