A sound coding strategy based on a temporal masking model for cochlear implants

Individual speech intelligibility results of the second study.
The blue line presents the average result from two HSM sentence lists (circles) for each temporal masking half-life (0.4, 0.5, 0.8 and 1.1 ms). The SNR for these measurements depends on the performance of the individual patient and ranges from 15 to 5 dB SNR as stated in Table 1. The subjects are ordered in columns according to the temporal masking half-life with the best speech intelligibility (indicated by a red arrow): patients with best results without temporal masking in the first column and patients showing best speech intelligibility with temporal masking constant T½ = 0.8 ms are in the fourth row. No patients showed optimal speech intelligibility with the strongest temporal masking constant of 1.1 ms.
