| The EASE 4.3 Tutorial states the following (page 177)
| Quote: | New STI Intelligibility Calculations
EASE and EASE JR now calculate STI using the MTI (Modulation Tranfer Index) values in accordance with the current IEC16 Standard
IEC60268-16:2003. ALcons and RaSTI intelligibility figures are then derived from the STI figures. |
The current version is 2011, the only aspect that I think would impact STI calculations would be the addition of the Upward Spread of Masking.
Does anyone have any thoughts on what that missing factor would do to results or have any thoughts on how we can correct for this?
I'm assuming the Upward Spread of Masking was added because it had an appreciable impact on STI results. |

| Answered my own question.
I noticed that in View Calculation on the Options Tab you can select IEC 60268 Edition 4.0 (2011)

| Hi,
Yes, IEC 60268-16:2011 has been incorporated already in EASE v4.4.5. Current version is 4.4.13.
As you said, the tutorial contemplates EASE 4.3 and will be updated. 
Latest changes can be checked in the upgrade history here: http://ease.afmg.eu/index.php/update-history.html
Kind Regards!
Pedro Lima |
