Current projects

Hearing aid noise reduction – Measured short-term average gain reduction

Aim

As a follow-up to the project where various noise reduction algorithms were evaluated using long-term measurements, the current project aims at describing how the noise reduction algorithms work in the short time frame.

Predictive measures of the intelligibility and sound quality of speech processed by noise reduction algorithms

Aim

This project is a follow-up to the finished study on Noise reduction in hearing aids - Predictive ability of computational measures in terms of speech intelligibility, noise loudness and sound quality .

Now, data for 10 normal-hearing listeners will be included, and additional predictive measures will be tested.

ORCA speech test in Swedish

Aim

During 2008, ORCA Europe’s sister organization ORCA USA developed a speech test for the American language. The goal was to develop a test that could be used to detect and analyze the effects a given signal processing algorithm has on different phonemes and/or phoneme groups. The aim of the current project is to create a Swedish version of the ORCA Speech Test.

Participants for future research

For the research that is carried out at the group’s own research laboratory, participants are currently being recruited to a data-base. If you live in the Stockholm area and you have a hearing loss, you are welcome to contact us if you are interested in participating in future research.
