Concerts and events can use a Target Level loudness to optimize sound exposure by ensuring parity of loudness between acts and show elements (broadband loudness normalization). This is not the case when using an \(L_p{_\text{,Aeq,}{_\textit{T}}}\) limit (A-weighted peak normalization).

The main benefit for stakeholders is parity of loudness across all show elements and acts – using a fairer, psychoacoustically correct measure. It’ll be useful to calibrate an electrical signal to \(L_p{_\text{,Aeq,}{_\textit{T}}}\), but what may be more beneficial is the improvement in sound quality.
