Discussion sessions - Friday, June 14th, morning

  

I. Hardware & Acoustics

2) Comparing hearing aids and personal sound amplifiers

Session chair: Andrew Dittberner (GN Hearing)


Short description:
Personal listening devices, also known as assistive listening systems or personal sound amplification products (PSAPs), share some functionalities with hearing aids, but can be bought without a prescription. Based on a review how PSAPs compare to hearing aids in technology, target users, legal regulations, cost, or functionality we will discuss what might be learned from PSAPS to be put into Hearing Aids and vice versa. How can Hearing Aids be compared to PSAPs with respect to near-to-normal listeners, e.g. by supporting premium sound quality for music perception and speech intelligibility as well as acoustic transparency?

II. Psychophysics & Evaluation

4) Hearing aid performance assessment in real life as compared to the lab: Refined concepts and new ideas

Short description:
The session will focus on laboratory tests and comparisons between results obtained in the laboratory and field. Further, various aspects of audio-visual presentation and context will be dealt with.

III. Algorithms  & Software

6) Using software tools and models for objective evaluation

Session chairs: Lars Bramsløw, Rainer Huber


Short description:
During the development of a hearing device or algorithm, the device under test must be evaluated using relevant outcome measures. Ideally, a listening test can be applied, at a given time and effort. Alternatively, objective metrics and models can be used to explore the algorithm and obtain an estimate of the expected performance. What tools are ideal for different problems and what are the limitations? The session focuses on recent tools and results in both approaches.
