Redistribution of the low frequency acoustic modes of a room: a finite element-based optimisation method

摘要

This paper presents a method to redistribute the acoustic modes of a room in the low fre- quency range. The relationship between the acoustic modes and the room geometry is studied. The fundamental problem of normalizing the acoustic modes of a simple, orthogonal room is Examined in depth. Several variable local geometric modifications of the room walls are intro- Duced and an optimisation procedure is developed. Based on finite element analysis.
