The Behavior of OpenSound Navigator in Complex Environments
Course: #33066Level: Intermediate 1 Hour 469 Reviews
Signal processing in hearing aids must be able to give the user benefits in a broad range of these complex environments. In this presentation, recorded waveforms from a range of different sound situations through several different advanced technology hearing aids will be presented, along with a discussion on how well the design and function of the various approaches handle different types of listening environments.
Learning Outcomes
- After this course learners will be able to explain how different signal processing approaches in high end hearing aids attack the speech in noise problem in different ways.
- After this course learners will be able to explain how to glean information about dynamic device performance by looking at various advance visual representations (such as spectrographs, waveforms, etc.).
- After this course learners will be able to explain how some systems can meet certain performance criteria (such as reduction of noises arising from behind) at the expense of other criteria (such as maintenance of a full gain response).
