Calculations of STI for several modeled sound fields show that the values of STI for the field consist of direct sound and single reflection, which is higher or lower by a dB than the former, are same, the sound reflections at any delay time raise up the value of STI and even the high level early sound reduces the value of STI under certain condition. The early sound energy might be useful for high speech intelligibility, whereas the concept of STI contradicts with that. There are problems to consider STI to be an adequate measure of speech intelligibility.
