Domain Adaptation in Acoustic Rainfall Sensors

Rainfall is increasing in frequency and intensity due to climate change. Hydrological models exist that can report bottlenecks in urban infrastructures. However, these require accurate rainfall estimations with high temporal and spatial resolution. The fulfillment of these requirements is challenged due to high costs. This can be solved with...

An automated ECG signal quality assessment method with supervised learning algorithm

Wearable health has become a striking area in our daily life.<br/>Electrocardiogram (ECG) is one of the biomedical signals collected by the wearable or portable devices, which is widely used in heart rate monitoring and cardiac diagnosis. However, automatic ECG signal analysis is difficult in real application because the signals are easy to be...

Interferer selection for binaural cue preservation in joint binaural linearly constrained minimum variance beamforming

Spatial cues allow a listener to determine the direction sound is coming from. In addition, recognising spatially separated sound sources facilitate the listener to focus on specific sound sources. Because of this, preservation of spatial cues in multi-microphone hearing assistive devices is important to the listening experience and safety of...

Outlier detection in multivariate time series: Exploiting reconstructions from random projections

Localization Algorithms for Conference Systems

This report details the design and implementation of a subsystem within a localization system designed for the Bosch DICENTIS wireless conference system. The goal of this localization system is to determine the location of individual units. These units each contain a microphone and a loudspeaker and are used by the participants at a conference....

The cocktail party problem: GSVD-beamformers for speech in reverberant environments

Hearing aids as a form of audio preprocessing is increasingly common in everyday life. The goal of this thesis is to implement a blind approach to the cocktail party problem and challenge some of the regular assumptions made in literature. We approach the problemas wideband FD-BSS. From this field of research, the common assumption of contineous...

Interactive Geometry-Based Acoustics for Virtual Environments Using the Graphics Card

The acoustics of a space contribute much to the perceived size and atmosphere of the environment. Modeling these acoustics in virtual environments can make a big improvement to the immersion of the player. There are very accurate models that can reproduce realistic acoustics in virtual spaces, but these are computationally very expensive....
