Statistical Analysis of the results

Aim: possible correlation between objective parameters measured inside the theatres and subjective descriptors.

Objective parameters choosen:

- Monophonic parameters: reverberation times T10,T20, T30, EDT; clarity C50 e C80; center time Ts; D50.

- Spatial parameters: Lateral Fraction(Lf) and Inter Aural Cross Correlation (IACC)

- Tonal parameters: Tonal Balance (TB) and Bass Ratio (BR)
