Abstract The  strong  link  between  acoustical  performance  and  architecture  has  been  well  established  since  the  birth  of  open-air  theaters  and  still  holds  true  to  this  day.  The  science  of  acoustics  continues  to  improve  primarily  due  to an ever-growing  body  of  knowledge  as  well  as  technological  interventions.  However,  it  seems  that  designers  of  performance  spaces  nowadays  are  still  facing  a  challenge  in  properly  designing  multi-purpose  spaces  such  as  an  auditorium  which  could  adequately  provide  for  the  varying  acoustical  requirements  of  musical  and  speech  performances.  Based  on this premise,  this  study  aims  to  conduct  a  deeper  examination  of  the  current  practice  of  acoustics  design  in  multi-purpose spaces and  identify  the  various  attributes  related  to  the  performance,  parameters  and  approaches  involved,  among  others,  in  the  application  of  adaptive  acoustics.  Furthermore,  this  study  proposes  a new approach in applying the concepts of adaptive  acoustics  systems  in  multi-purpose  spaces.  It  will  employ  the  analysis  of  existing  applications  as  backdrop  and  will  demonstrate the merits of this new approach through computer simulation.  The study aims to answer the following questions:  1. 2. 3. 4.

Is adaptive acoustics an effective way to provide ​ideal acoustics​ both for musical and speech performance?  Which  adaptive  acoustics  strategy  has  the  greatest  potential  to  be  applied  and  adopted  in  the  actual  design  practice and industry?  How can this strategy be translated into an architectural solution? How is this expected to perform?  In  what  ways  can  the  proposed  solution  be  refined  and  optimized  to  encourage  its  adoption  by  design  professionals and the industry?
