New paper suggests that musical pitch information is not adequately provided by temporal information for cochlear-implant or normal-hearing listeners.
We have a new paper out in Trends in Hearing. In this paper, we played a song (Happy Birthday) using temporal information only to both cochlear-implant (CI) and normal-hearing (NH) listeners. Both groups were insensitive to changes in tuning (i.e. if the melody was played in or out of tune) when played using only temporal information. However, listeners were highly sensitive to changes in tuning when played using pure tones (i.e. with both temporal and place information). These results suggest that temporal coding of pitch is insufficient to convey proper musical intervals. Furthermore, listeners with a CI in one ear and NH in the other performed like NH listeners with the NH ear and CI listeners with the implanted ear, suggesting that the limitations in CI performance are not related to CI listeners’ lack of familiarity with music perception.

We've got a new paper out on the use of research interfaces with cochlear implants. Its also my first paper with Ruth Litovsky, Matt Goupell, and Alan Kan.

We received this really cool "Thank You" note from Matt Winn and the Listen Lab at the University of Washington. I love the handshake / high five between the Listen Lab mascot (left) and the Ear-Lab mascot (right). I've been meaning to post this for quite a while now.
This is where we provide updates from the lab
