SPAT distance vs. "real world" distance

Spat
#1

Hi!

Just out of curiosity, have you made experiments comparing the distance sensation of a “real world” experiment with loudspeakers placed at different distances, and using the SPAT distance slider, with drop mode (log2), air absorption (on) and drop (6 dB). (This should be the most “natural” settings for the distance, right?).

And if so - what were the results, are the two sensations equivalent? Are the paper available for reading?

good day! :slight_smile:

Interesting question.

  • I’m not personally aware of any such experiments.
  • Yes, the settings you proposed are the most “natural” ones.
  • The spat paradigm kind of implicitly assumes that the speakers are far enough, well oriented (i.e. towards the listener-centred sweet spot) and calibrated (delay/gain aligned, frequency response compensated, etc), so that they can be considered as “perfect”/omnidirectional transducers.
    Given these assumptions, and if you properly adjust the “radius” slider according to your speakers layout, the distance slider should create similar auditory “sensations”.

That sounds good! I will see if I can get an opportunity to make the comparison :slight_smile: Thank you for your reply!
