as mentioned before, the floor reflection is a very strong distance cue at close range under semi-anechoic conditions (i.e. if you want to gauge the distance of that sabre-toothed tiger or the potential mating candidate).
uhm, i realise that the latter example is a bit dated - who meets significant others in the great outdoors, these days. for clubbing, the dominant cue should be direct-to-reverb ratio, unless you have to fall back to olfactory and visual cues entirely because of the extremely loud music.
if you're right next to the sound source, the floor reflection will have the longest delay. far away, the delay will be negligible. the general case is dly = 340 / (sqrt(ear_height^2 + half_distance^2) * 2)
minus the straight-path delay of course: dly = 340 / (sqrt(ear_height^2 + (distance/2)^2) * 2 - distance) -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
