+Supplemental Audio
+- Audio 1
+    - Example audio excerpts for each of the 33 background conditions for Experiment 1. All of the three-digit sequences are delivered at an SNR -9 dB. Exemplars for each of the 11 background sound conditions are organized in a directory corresponding to the experimental manipulation performed (OR, PR, SE). Sounds are numbered from 1 to 11 in rank order according to the perceptual accuracy, as in Fig. 1C (Sound01.wav, Sound02.wav, etc.).
+- Audio 2
+    - Example audio excerpts for each of the background conditions for Experiment 2. The background conditions include the babble-8 and jackhammer backgrounds delivered at variable SNR and variable statistics (Spec, +Mar, +MPS, +Corr, and Orig). Sounds are organized in subdirectories corresponding to the SNR condition (-12, -9, -6, and -3 dB) and background name (EightSpeakerBabble or Jackhammer) and are labeled according to the summary statistics used to synthesize the background (SoundSpec.wav, SoundMar.wav, SoundMPS.wav, SoundCorr.wav, SoundOrig.wav).
