Room Acoustical Parameters as Predictors of Acoustic Comfort in Outdoor Spaces of Housing Complexes [PDF]

Frontiers in Psychology, 2020
Room acoustical parameters have frequently been used to evaluate or predict the acoustical performance in rooms. For housing complexes in urban areas with high population density, it is important to improve acoustic performance not solely indoors, but ...

A note on meaningful acoustical parameters for open-air theatres

Acta Acustica, 2023
The acoustics of performance spaces are usually characterized by the reverberation time and a handful of other acoustical parameters defined in ISO 3382-1. However, these parameters have been derived with closed spaces in mind, and it is not obvious that
