| Abstract | Legally enforced sound level limits are typically expressed as a single A-weighted equivalent continuous sound level (LAeq) for sound system operators. LAeq is not guaranteed to always align with perceived loudness, and there are potential health implications due to sound exposure in spectral bands that are suppressed with A-weighting. This paper discusses the appropriate application of EBU R 128 loudness normalization metering for sound reinforcement systems, applied with reference to pre-determined sound level limits at a venue. The proven application, which is standard practice in the broadcast industries, enables skilled operators to focus upon delivering an electrical system input signal of repeatable and consistent loudness. A feasibility study analyzing the relationship between weighted and unweighted sound levels will be presented, including results from a small sampling of recent events in the UK. |
