TABLE III.

A LME model fit by REML for the response variable ΔSPL (dB) including as fixed factors the terms (1) style, (2) room, (3) panel, and (4) chronological order (“order”) with interactions of (5) room and style, (6) room and order, (7) style and gender, and the interaction of subject and time as a random effects term. As within-subject normalization was performed, it is not possible to appreciate whether or not there was a main effect of gender on ΔSPL. Reference levels are the normal style, the semi-reverberant room, absent panels, and female gender. R. = room; st. = style; Signif. = Significance; Semi-reverb = Semi-reverberant.
