Semi-active (also known as adaptive-passive) control is an adjustable passive sound/Vibration control scheme. That is, the passive treatment can adjust itself, in response to changes in the acoustic system/structure. For example, the stiffness, damping coefficient or other tunable parameters of the passive control scheme can change automatically, or be optimized via a properly developed semi-active control algorithm.
Being more versatile than passive control techniques and more affordable (in terms of cost and energy consumption) than active control schemes, have made semi-active control methods very popular.
We invite experts in this area to present papers for any innovative applications, case studies, experimental verification and/or simulations.
We also invite authors to submit papers on experimental techniques and test results regarding structural vibrations, vibratory power flows, sound radiation from vibrating structures, identifications of structural/acoustic parameters, and so on. Both case studies and generic investigations are welcome.
