Role and responsibilities
Develop and maintain hearing device features to deliver exceptional user benefits and outstanding listening experiences. Parameterize hearing device functions using MATLAB, Simulink or Python and optimize performance to meet speech intelligibility and sound quality requirements. Use AI methods and tools to develop and optimize audiological features and evaluate sound performance of DNN-based solutions. Build firmware images and measure performance of hearing devices in an acoustic test box, a fully equipped acoustic lab (with KEMAR), or a dedicated electrical audio setup and provide evidence-backed performance metrics. Define the metrics and evaluation methods and develop tests for sound quality and feature performance evaluation. Create audio recordings with hearing devices and dedicated equipment to prepare stimuli for device testing. Conduct experiments with subjects to understand subjective performance in real-world scenarios. Contribute to feature integration and system verification activities, conduct tests and provide expert feedback on device sound performance. Closely collaborate with audiological research, signal processing, AI, data insights, software engineering, and other R&D teams. Support the marketing department by providing improvement ideas, claims metrics, conducting competitive intelligence studies and preparing technical setups for sound demos.
