The acoustic characterisation of indoor spaces is crucial for a wide range of applications. While global metrics provide convenient descriptors of a room's overall behaviour, a more spatially detailed analysis offers deeper insight into the spatio-temporal structure of the sound field, albeit at a higher experimental cost. This paper proposes a methodology that leverages the predictive capabilities of sound field reconstruction methods to estimate room acoustic parameters as a function of position. The approach is experimentally evaluated in an auditorium, where it achieves accurate estimation of temporal; energetic room acoustic parameters across the entire audience area. In addition, the reconstructed field yields higher intelligibility indices compared to the raw measurements. Overall, these results highlight the potential of sound field reconstruction techniques as a practical tool for room acoustic characterisation; for supporting assistive listening technologies.
