Assessment of Music Audio Quality in a Sports Stadium
This study investigates subjective and objective parameters of a sound reinforcement system in a large sports stadium. The sound at fourteen groups of three receiving positions was studied in a subjective listening test, as well as through objective system measurements. For an orchestral music sample, seventeen system tunings were subjectively assessed with fifteen scales. Objective measurements were made at each receiving position. Results showed significant variation for many of the subjective scales between tunings, as well as between receiving positions. To some extent, subjective and objective measurements were related as they describe system tuning and receiving position. Beyond its specific results, this study highlights a range of difficulties in empirically assessing audio quality for music in a very large venue.
