Binaural Beamforming Algorithms and Parameter Estimation Methods Exploiting External Microphones (2020)
Abstract / truncated to 115 words
In everyday speech communication situations undesired acoustic sources, such as competing speakers and background noise, frequently lead to a decreased speech intelligibility. Over the last decades, hearing devices have evolved from simple sound amplification devices to more sophisticated devices with complex functionalities such as multi-microphone speech enhancement. Binaural beamforming algorithms are spatial filters that exploit the information captured by multiple microphones on both sides of the head of the listener. Besides reducing the undesired sources, another important objective of a binaural beamforming algorithm is the preservation of the binaural cues of all sound sources to preserve the listener's spatial impression of the acoustic scene. The aim of this thesis is to develop and evaluate advanced ... toggle 10 keywordsspeech enhancement – multi-microphone – hearing aids – binaural hearing – acoustic sensor networks – binaural cues – beamformer – mvdr – lcmv – relative transfer function
