Efficacy Of Using Spatial Averaging In Improving The Listening Area Of Immersive Audio Monitoring In Programme Production

Loudness-based production in broadcast relies on accurate monitoring for judging balance, formats, speech intelligibility, and audio quality. Reproduction systems for monitoring immersive audio presentations share certain assumptions about the monitoring system setup. These include flat frequency response at the listening location, normalized monitoring level, and the same level and time of flight from all monitors to the listening location. The boundary loading in the monitoring rooms tends to modify the frequency responses of the different loudspeakers in the immersive monitoring system, uniquely for the specific location of each loudspeaker. When using equalization to remove response differences between loudspeakers, no significant differences were found between single point measurements and spatial averages for small spatial averaging displacements in rooms having low reverberation times.
