Applications of Multifractals in the Analysis of Room Impulse Response - Initial Research

Abstract

The analysis of impulse response has a central place in room acoustics. The research presented in this paper was aimed at examining possibilities for applying multifractal theory in room acoustics focusing on the analysis of room impulse response. Observing an impulse response as a signal with multifractal features gives an opportunity for a new approach in determining the acoustic properties of a sound field in a room. Through the use of characteristic values, gained from multifractal spectra, authors have tried to quantify impulse responses of different rooms. The method used in this paper, together with achieved results, is displaying some of the directions which can be followed when applying multifractals in the field of room acoustics.
