Discussion sessions - Friday, June 2nd, morning
Session chairs: Volker Hohmann (Oldenburg), Chas Pavlovic (Palo Alto)
Short description: Open source solutions and publicly accessible development platforms for hearing device research and prototyping have appeared on the screen as a kind of “Linux for Hearing aids”. The NIH has even launched a program to support such solutions. The session will discuss the utility, perspectives and possible risks of these developments.
10.00 Volker Hohmann (University of Oldenburg) and Chas Pavlovic (BatAndCat Corp.): Introduction
10.05 Chas Pavlovic (BatAndCat Corp.): NIH (NIDCD) initiative to develop real-time portable signal processing tools for advancing research on hearing loss compensation
10.25 Bradford Backus (Oticon Medical): Hacking into the auditory nerve-can we open source the brain?
10.45 Hendrik Kayser (University of Oldenburg): The open Master Hearing Aid
11.00 General discussion, Part I
11.15 Coffee Break
11.45 Stefan Launer (Sonova): Open DSP platforms for hearing instruments - the manufacturer’s perspective
12.05 Stefan Stenfelt (Linköping University): A master hearing aid system for auditory tests of hearing impaired people
12.25 Inga Holube (Jade University of Applied Sciences): An open-source mobile device for outside-lab sound field research
12.40 General discussion, Part II
12.55 End of session
II. Signal processing and algorithms
B) Binaural hearing aid fitting, superdirectivity and evaluation
Session chair: Peter Derleth (Sonova)
Short description: Binaurally fitted hearing aids with superdirective beam-forming techniques will become more widely spread in the market. From the fitters and customers perspective there is the question for whom (candidacy) and when (listening situation) these technologies should be selected. This session tries to put some light on the benefits and challenges of this technology under real world conditions.
10.00 Michael Syskind Pedersen (Oticon): Directivity for real world benefit
10.15 Michael Akeroyd (Nottingham): Environmental awareness vs. focused listening & SNR improvement vs. spatial hearing
10.30 Markus Hofbauer (Sonova): Binaural beamforming in theory and practice
10.45 Henning Puder (Sivantos): Possibilities for the evaluation of the benefit of binaural algorithms using a binaural audio link
11.00 Peter Derleth/Harvey Dillon: General discussion, Part I
11.15 Coffee Break
11.45 Tao Zhang (Starkey): Robust adaptive binaural beamformer (no slides available)
12.00 Rob de Vries (GNResound): Biomimicry-based Spatial Unmasking Design in Beamforming
12.15 Dirk Oetting (Oldenburg): Binaural loudness compensation: beamforming without amplification?
12.30 Peter Derleth/Harvey Dillon: General discussion, Part II
12.55 End of session
III. Psychoacoustics and fitting
B) Borderline patients and the bridge between hearing aids and cochlear implants
Session chair: Richard Dowell (Melbourne)
Short description: Cochlear implants can now outperform hearing aids for some people with severe hearing loss for whom hearing aids provide significant benefit. This session will address the question of when are cochlear implants the best solution, when are hearing aids the best solution, and when the best solution requires both to be worn by the same person. The session may also cover theoretical reasons why, in the latter case, the processing in the two different devices should be coordinated in some way, and whether there is as yet any evidence that doing so provides benefit over having two devices with independent processing systems.
10.00 Richard Dowell: Introduction
10.15 Tom Francart: What can hearing aids do well (better than cochlear implants)?
10.30 Volkmar Hamacher: What can cochlear implants do well (better than hearing aids)?
10.45 Andreas Büchner: What factors are important in predicting success with a cochlear implant?
11.00 Coffee Break
11.45 Tom Francart: How well do cochlear implants work with hearing aids in the opposite ear?
12.00 Waldo Nogueira: Electrical and auditory stimulation in the same ear (EAS)
(no slides available)
12.15 Volkmar Hamacher: Latest results for preservation of residual hearing after cochlear implantation
12.30 Tim Jürgens: Bilateral cochlear implants
12.45 Andreas Büchner: Evaluation and fitting cochlear implants – what is required?
13.00 End of session
