Compensation of Loudspeaker Frequency Response for a Wider Listening Area
Beránek, Šimon ; Říha, Kamil (referee) ; Schimmel, Jiří (advisor)
This bachelor thesis studies problematics of calculating average impulse responses of rooms. Measuring signals like MLS or linear/exponential sine sweep are described. Basic methods of interpolation are explained and their applicability in frequency response calculations is described. Digital filters are explained as a tool for frequency response equalization. First part of this thesis tests methods of interpolation on 64 measured impulse responses. These methods have been further optimized and one was chosen to calculate the average impulse response for each of the measured rooms. Second part consists of AB*X listening tests deployed to find subjective aural differences of the interpolated impulse responses and few of the measured impulse responses. These interpolated impulses responses were further compensated using a warped filter library.
