Achieving clear speech in the Holy Name of Jesus Cathedral in Raleigh

This study investigates the methods employed to achieve clear speech in the Holy Name of Jesus Cathedral in Raleigh. A comprehensive acoustical model was developed to assess the cathedral's acoustic properties. Ray tracing analysis was utilized to evaluate various sound system designs, focusing on their effectiveness in enhancing speech intelligibility. A detailed review of the speech-related parameters derived from these analyses was conducted. The final sound system design is described, highlighting its essential characteristics. Auralizations were created to illustrate the performance of the implemented system, demonstrating its capability to enhance auditory clarity in the cathedral's acoustically challenging environment. These findings contribute valuable insights into effective analysis and overall sound system design for similar venues. The loudspeaker element design of the sound system was by the late Frederick C. Schafer.
