Abstract ODEON modeling software is widely used by acoustic engineers to design rooms so they contain a set of desired acoustical characteristics, such as the reverberence of a concert hall or the privacy of an office complex. ODEON is also used by research groups to simulate environments, which can be used for, amongst other things, speech intelligibility experiments. However, the validity of such speech intelligibility experiments is called into question as no direct comparison between real room speech intelligibility results and simulated room speech intelligibility results has been made. This project compares speech intelligibility measurements made in real room situations with speech intelligibility measurements made in equivalent ODEON-simulated rooms. Comparisons of speech transmission index values in the real rooms and the ODEON-simulated rooms are carried out. Speech intelligibility results from 15 test subjects have been measured and are presented.
