Verification Measurements for Acustica Paper Complete

I just finished taking verification impulse responses in the physical locations that I conducted subjective experiments in this past semester. These results will be used in an upcoming Acustica paper that I am submitting.
ABSTRACT:
The subject of auditory visual integration has become increasingly important with the introduction of high-resolution playback devices that allow for a high level of granularity in ob ject segregation on-screen. What, if any effect does the visual impression of a ob ject in a scene have on the sub jective impression of that ob ject’s auditory stimulus? Several studies have looked at the phenomenon in recent years, but limit the testing condition to static images, speech-only signals or photographs to represent the visual scene. In this paper we examine, with a high-definition visual presentation, the impact of a musician’s visual performance on the sub jective impression of that musician’s auditory performance. Moreover, this study reveals listener resiliency in the presence of forced auditory visual mismatch; respondents are able to adjust the acoustic modeling algorithm using the salient parameters of direct to reverberant ratio and reverberation time to match the acoustic performance given the visual test condition. Sub jective results of the experiment are presented, as well as objective verification measurements.
