Reverberation in experiments is graded by physical source-receiver distance

Evidence

Reverberation was added by convolution with real-room impulse responses recorded in a long corridor, at source-receiver distances of 0.32, 2.5, and 10 m (Tony Watkins; University of Reading, UK). We refer to these as “mild”, “moderate” and “strong” reverberation. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5031
