This study showed that the overlap of practically-used bandpass filters can influence the octave band decay curves, especially if the decays are calculated from a filtered impulse response that has been created from octave band energy responses. Energy from a frequency band with a long reverberation time can leak into a neighbouring band with a shorter reverberation time. This also means that neither octave band decays from a measured response are independent, nor are measured octave band reverberation times.
