Table 1
Main experimental results in terms of measured T30, EDT, C80, TS, STI values in octave bands. The values refer to sound source position S1 (see Fig. 3) and they have been averaged over all the receivers in the ottangulo, as it is the core of the present study (see Fig. 2). The standard deviations are provided in brackets.
