Advances of acoustic research in coupled spaces

Abstract

Coupled space widely exists in theatres, concert halls, large religious buildings, factories and other buildings, and its sound field is complex. Although some scholars have carried out relevant studies by means of sound field computer simulation, acoustic scale model test and field measurement, there are still a lot of problems unsolved. In this paper, the characteristics of coupled space sound field and the research progress of coupled space sound field in concert hall and theater are reviewed.
