An integrated model of pitch perception incorporating place and temporal pitch codes with application to cochlear implant research
2017, Hearing ResearchCitation Excerpt :Furthermore, although the pitch perception theories are derived from normal hearing (NH) auditory behavior, listeners with cochlear implants (CIs) have been shown to employ similar pitch perception cues to make pitch decisions (e.g., Tong et al., 1983 and Nelson et al., 1995). In CI hearing, however, pitch perception cues are not as effective as in NH due to inability of implants to provide sufficient pitch information or due to cochlear changes caused by deafness (e.g., Blamey et al., 1996, Carlyon and Deeks, 2002, Schatzer et al., 2014). Researchers are still investigating how an implanted ear makes use of the pitch information present in electrical stimulation and what would be a more effective way of encoding pitch through trains of electrical impulses (e.g., Geurts and Wouters, 2004, Green et al., 2004, Vandali et al., 2005).
Frequency-place map for electrical stimulation in cochlear implants: Change over time
2015, Hearing ResearchCitation Excerpt :For a given angle of insertion, acoustic pitch matches tended to be lower in frequency than predicted by the Stakhovskaya et al. (2007) SG frequency map. Although there have been multiple reports of acoustic matches to single electrode stimulation, most previous reports have been limited by severely impaired acoustic hearing (e. g. Reiss et al., 2007, 2014; McDermott et al., 2009), adaptation to a speech coding strategy (e. g. Baumann et al., 2011; Schatzer et al., 2014; Zeng et al., 2014), or both (e. g. Blamey et al., 1996; Boëx et al., 2006). Carlyon et al. (2010) and McDermott et al. (2009) found place-pitch matches with inexperienced implant users to be closer to either the Greenwood (1990) organ of Corti estimate or the Stakhovskaya et al. (2007) spiral ganglion estimate.
Application of a pitch perception model to investigate the effect of stimulation field spread on the pitch ranking abilities of cochlear implant recipients
2014, Hearing ResearchCitation Excerpt :The structure of the cochlea and the distribution of the 200 auditory neurons were the same as described in the previous section. However, the depth of electrode insertion varies among implantees (see for example Ketten et al. (1998)) and the Greenwood frequency-position cannot be presumed for electrical hearing (Blamey et al., 1996; Schatzer et al., 2014). Thus, the auditory neurons are represented by their order (1–200, with one being the most apical) and not their CFs.
Electric-acoustic pitch comparisons in single-sided-deaf cochlear implant users: Frequency-place functions and rate pitch
2014, Hearing ResearchCitation Excerpt :Many of these studies found that the pitch elicited through stimulation of intracochlear electrodes was generally between one and two octaves below Greenwood's estimate (1961, 1990) for the frequency-place function in humans (Blamey et al., 1996; Boëx et al., 2006; Dorman et al., 2007). Blamey et al. (1996) conducted pitch-comparison experiments in 13 subjects with relatively poor hearing in their non-implanted ear. Results were quite variable across subjects, and the pitch elicited through stimulation of intracochlear electrodes was generally between Greenwood's prediction and three octaves below that prediction.
