Optimizing Teaching Room Acoustics: A Comparison of Minor Structural Modifications to Dereverberation Based on Smoothed Responses
In this work a comparison between traditional acoustical treatment, such as building material substitution, and digital room acoustics dereverberation is presented for teaching rooms. Measured responses for a number of listening positions for two rooms are shown as well as relevant parameters namely T30, EDT, C-50 and STI. Corresponding values are calculated by employing a simulation model in order to verify its accuracy; minor changes are then introduced to the model aiming to improve speech intelligibility and a new set of parameters is obtained. Finally, dereverberation achieved from inversion of appropriately modified measured room responses based on Complex Smoothing is employed and the acoustical parameters from the filtered impulse responses are derived.
