An isogeometric Burton-Miller method for the transmission loss optimization with application to mufflers with internal extended tubes
TL;DR: In this article, the authors studied the problem of a muffler with internal extended inlet/outlet tubes with the aim to optimize its geometric design, and proposed an isogeometric BM (IGA-BM) model to solve the muffler problem as an interior 3D Helmholtz acoustic problem.

Numerical investigations with eXtended isogeometric boundary element analysis (XIBEM) for direct and inverse Helmholtz acoustic problems
TL;DR: In this article , two numerical investigations are performed using XIBEM for two-dimensional problems, and the number of plane waves is varied to find out the suitable enrichment scheme to achieve accurate results for higher frequency problems than those in the literature.
