ASA 143rd Meeting Lay Language Papers -When Sound Effects Are Better Than The Real Thing Over 70% of the time (a statistically significant percentage), listeners preferred the synthesized event to either the real or Foley stimulus for the �walking in mud� stimuli. This was also found for the �walking in leaves� stimuli. No significant preference was determined for the �crushing eggshells� stimulus. Future tests will apply this technique to a broader range of sounds.
