| In EASE versions prior to 4.3, %Alcons was only available for 500, 1k, and 2k Octave bands, but only in a Standard EASE Mapping. When you predicted an Impulse Response in AURA, STI was calculated according to the IEC 60268-16 international standard. %AlCons has no such standard even regionally, so EASE 4.3 now calculates STI directly for both types of maps. With STI you can see the octave band contributions by looking at MTI (switchable on the options tab when viewing maps). This gives you the values for all octave bands. I t also allows you to include ambient noise and the effects of masking according to the standard.
HTH,
