The acoustic quality of a performing arts centre is a key factor in determining its overall success
and functionality. Although elements such as construction materials, sound reinforcement systems,
and interior finishes play important roles in shaping the acoustic environment, the architectural
geometry of the space remains one of the most influential design factors affecting sound behaviour.
The form and configuration of a building influence sound reflection, diffusion, reverberation,
clarity, and speech intelligibility, which collectively impact both audience experience and
performer comfort. This study explores the influence of architectural geometry on acoustic
performance in a Centre for Performing Arts located in Port Harcourt, Nigeria. Adopting a
qualitative research approach, the study relies on an extensive review of existing literature, case
study and theoretical acoustic assessments to examine how various geometric forms affect sound
distribution within performance spaces. The findings indicate that factors such as room shape,
ceiling configuration, wall orientation, spatial volume, and surface geometry have a significant
effect on acoustic performance. Furthermore, the study highlights several architectural design
strategies capable of improving acoustic conditions while preserving the aesthetic appeal and
functional requirements of the facility. In conclusion, the research shows that incorporating
acoustic considerations at the early conceptual design stage can contribute significantly to the
development of more efficient, functional, and sustainable performing arts centres. Based on these
findings, recommendations are proposed for architects, acoustic consultants, and policymakers
involved in the planning and design of cultural and performance-oriented buildings.
