New Paper: Determining the Minimum Number of Electrodes That Need To Be Pitch Matched to Accurately Estimate Pitch Matches Across the Array.
We've got a new paper out from our collaboration with Justin Aronoff and Julia Stelmach from the Binaural Hearing Lab at the University of Illinois.
In this paper, we found that nine pitch matches are sufficient for accurately determining pitch matches across the array. This requires approximately 7 min of testing, indicating that accurate pitch matching can be accomplished in a clinically feasible timeframe.
This new paper shows that spectral resolution improves with age for normal hearing children (green dots/line), but not with children with cochlear implants (blue dots/line). Furthermore, adults with cochlear implants (that lost their hearing after developing language; blue box plot) have better than spectral resolution than children with cochlear implants. As children with cochlear implants can perform very well, the data suggests that children and adults with cochlear implants may differently weight cues. If so, this would suggest that implanted children may benefit from different cochlear implant processing strategies than adults.
This paper is the first pediatric paper out of the EAR Lab as well as our first from our collaboration with Laurie Eisenberg and Amy Martinez at the University of Southern California.
