      Sound level management at live events has been made immeasurably easier over the past decade or so through use of commercially-available sound level monitoring software. This paper details a study conducted at a large-scale multi-day music festival in Chicago, USA. The focus was twofold: first to explore how the use of noise monitoring software affects the mix level from sound engineers and second on how crowd size, density and distribution affect the mix level. Additionally, sound levels at various points in the audience were monitored to indicate audience sound exposure over the duration of the festival. Results are presented in relation to those from previous studies with key findings pointing towards recommendations for best practice.
    • A case study on the impact list event sound level regulations have on sound engineering practice

      Sound level management at live events in becoming increasingly common at live events in the UK, Europe and beyond. An inspection of regulations across the globe reveals a lack of standardization for sound level limits and averaging times. This case study is formed around a dataset generated on a recent tour by a well-known British musical act. The same sound engineer mixed the band throughout the tour using sound level monitoring software throughout. As the show’s configuration, engineer, musicians and running order were generally consistent day-to-day, the direct inspection of the influence of sound level limit and averaging time, as well as venue capacity and type (indoors or outdoors), is possible. The results from this study highlight both good and bad sound management practice, with key stakeholders’ experience and hearing safety in mind.
    • Understanding and managing sound exposure and noise pollution at outdoor events

      Hill, Adam J.; University of Derby (Audio Engineering Society, 2020-05-22)
      This report is intended to present the current state of affairs surrounding the issue of outdoor event-related sound and noise. The two principal areas of investigation are sound exposure on-site and noise pollution off-site. These issues are different in nature and require distinct approaches to mitigate the associated negative short-term and long-term effects. The key message that is presented throughout this report is that the problems/ambiguities with current regulations are due to a lack of unbiased, scientifically-based research. It is possible to deliver acceptably high sound levels to audience members in a safe manner (minimizing risk of hearing damage) while also minimizing annoyance in local communities, where solutions to the on-site and off-site problems should begin with a well-informed sound system design. Only with a properly designed sound system can sound/noise regulations be realistically applied.
