Abstract

An overview is given on a case study on a telephone conference unit. First, some theoretical basics of the full structure/acoustic problem are presented and commented. Second, the Finite and Boundary element model is introduced. Finally, results are analyzed and practical solutions are brought to improve the acoustic receive performance.
