TABLE 5.

A list of stimuli used in experiment 2

Stimulus No. Left Ear Right Ear Set A Set B Description
1 Full bandwidth — x x Normal hearing ear only
2v — Vocoded full bandwidth x x CI simulation only
3v Full bandwidth Vocoded full bandwidth x x Acoustic and CI simulation
4 Low-pass filter: 250 Hz — x — Hearing loss simulation
5 Low-pass filter: 500 Hz — x — Hearing loss simulation
6 Low-pass filter: 1000 Hz — x — Hearing loss simulation
7v Low-pass filter: 250 Hz Vocoded full bandwidth x x Bimodal user simulation
8v Low-pass filter: 500 Hz Vocoded full bandwidth x x Bimodal user simulation
9v Low-pass filter: 1000 Hz Vocoded full bandwidth x x Bimodal user simulation
10v Low-pass filter: 250 Hz Vocoded high-pass filter: 250 Hz — x Bimodal simulation without overlapping frequencies
11v Low-pass filter: 500 Hz Vocoded high-pass filter: 500 Hz — X Bimodal simulation without overlapping frequencies
12v Low-pass filter: 1000 Hz Vocoded high-pass filter: 1000 Hz — x Bimodal simulation without overlapping frequencies
13 6-channel noise vocoder with 6.5 mm shift — x x Low quality anchor stimulus which presumably sounds worse than all other stimuli

Note that some conditions (1, 4, 5, 6, 13) are identical to those in experiment 1 while other conditions represent vocoder versions of the corresponding conditions in experiment 1.
