This paper presents the research that was aimed at examining the possibilities for improving the multifractal method for detecting early reflections in the room impulse response. Multifractal method for the detection of early reflections uses distribution of Hölder’s exponent calculated for the acoustic impulse response. Modifications of algorithm proposed in this paper perform filtering of the distribution of Hölder’s exponent to improve the detection of significant early reflections. The results obtained in this way provide guidance how to improve detection of early reflections and to make it more precise
