What do I need to consider when calculating Standard conform STI calculations?
EASE 5 supports the latest standard edition IEC 60268-16:2020. To perform standard compliant STI calculations, we recommend to proceed as follows:
In the IEC 60268-16:2020 standard, since Edition 2020 (Edition 5.0), only a male speaker is provided as the excitation signal. To enable that signal, go to the ACOUSTIC PARAMETERS Window and click on the INPUT SIGNAL Tile. In the PROPERTIES - INPUT SIGNAL Window select Speech.
After running a Mapping calculation, in the VIEW CALCULATION Window go to the OPTIONS tab and select Edition 5.0 and STI weighting Male (these are the default options). For more realistic results, you could also select Consider Noise Levels or Signal Masking which are included in the IEC 60628-16 as optional features. Those selections are post processing settings for the MTI and STI calculation.
