On the control of the absorption of an Acoustic Black Hole by using attached point supports

The Acoustic Black Hole (ABH) embedded in a beam is a termination that provides effective vibration absorption. The ABH effect, usually achieved by adding a visco-elastic coating in the flexible part of the termination, results in a reflection coefficient that varies with frequency, with local maxim...
