15.2.2 INTERACTION WITH THE A.P. CONTROL PANEL
It is possible to interact with the acoustical parameters control panel simply clicking
on the parameters data table.
To enter the impulse display mode simply click on the table first row and select
the desired octave band of interest; the selected column will change accordingly
and the decay (or ETC) will also follow. The Fig.15.1 shows the selection of the
1kHz octave to which corresponds the ETC calculated.
The leftmost column gives wideband parameters (Lin) calculated over the whole
available bandwidth. The rightmost column gives wideband parameters (A)
calculated applying an A-Weighting filter.
To enter the frequency display mode simply click on the table first column and
select the desired parameter whose behavior versus frequency should be displayed;
the selected row will change accordingly. The following figure shows the selection of
the RT20 row and its behavior vs. frequency (black curve); in comparison the
overlays show RT30 (green curve) and RTUser (red curve). It is not possible to
selects the three rows of the correlation coefficients (see below) of the calculated
RT60.
