Modelling the Effects of Spectator Distribution and Capacity on Speech Intelligibility in a Typical Soccer Stadium

Public address system performance is frequently simulated using acoustic computer models to assess coverage and predict potential intelligibility. When the typical 0.5 speech transmission index (STI) criterion cannot be achieved in voice alarm systems under unoccupied conditions, justification must be made to allow contractual obligations to be met. An expected increase in STI with occupancy can be used as an explanation, though the associated increase in noise levels must also be considered. This work demonstrates typical changes in STI for different spectator distribution in a calibrated stadium computer model. The effects of ambient noise are also considered. The results can be used to approximate expected changes in STI caused by different spectator occupation rates.
