Musical note duration flattens reflection thresholds much like room reverberation does

Evidence

First, it appears that the slower paced, longer, notes in the music cause the threshold curves to be flatter than they are for the more compact syllables and consonant sounds in speech. This “prolongation” appears to be similar in perceptual effect to that occurring due to reflections in the listening environment (Figure 6.7). — Toole, Floyd E, Sound reproduction- the acoustics and…, 638
