Comparison of frequency responses calculated across different time-windowed impulse responses for assorted types of rooms

Abstract

Recent work by Lokki et al. (2015) has shown that analyzing how frequency responses from concert halls change over different time-windowed periods of the impulse response across low, mid, and high frequencies correlates well with human perception of how well the space performs. In this project, such frequency response analyses across different time-windowed impulse responses are applied to spaces other than concert halls to include a variety of classrooms, worship spaces, and speech-centered performance spaces. Preliminary results from the study will be presented, with particular focus on comparing spaces designed primarily for speech, music, or both.
