Background
In the research and development of new hearing devices, it is essential that evaluation is thorough and rigorous.
There is evidence to suggest that ‘listening performances’ in current laboratory settings do not adequately replicate performances in real life, thus limiting the evaluation outcomes. This discrepancy is likely to increase with the increased sophistication of signal processing in new generation hearing devices.
At least three factors are thought to influence the listening performance in the laboratory:
1. monophonic and stereo presentations do not sound realistic
2. non-aural information is not available
3. the listening task is unfamiliar or unrealistic, or both.
Detail
While the project Laboratory simulation of 3D real-world environments addresses points 1 and 2, this project addresses the third factor and aims to develop interactive tests for evaluation of sophisticated signal processing in hearing devices in a simulated 3D real-world environment.
This project will develop new laboratory tests that better predict the real-world performance of sophisticated signal processing in hearing devices when presented in a 3-dimentional loudspeaker array with visual cues.
