Development and Analysis of Real-Time Acoustic Feedback Cancellation and a Clinical Testing Simulator for Hearing Studies
(2018-07-18)
Acoustic feedback stems from acoustic coupling between the loudspeaker and microphone in
hearing systems. Unpleasant outcomes of acoustic feedback, such as howling and whistling
sounds, are major complaints of people ...
Real-Time Smartphone Apps Integrating Signal Processing Modules of Hearing Aids
(2018-05)
This thesis covers the integration of several signal processing modules that appear in digital
hearing aids as real-time smartphone apps. The modules that are considered for integration in the
developed apps in this ...

Dual Microphone Speech Enhancement Algorithms on Android-Based Devices for Hearing Study
(2018-08)
Speech Enhancement (SE) is a key module in the Hearing Aid (HA) signal processing pipeline
and improves the listening comfort. Over the last few decades, researchers have developed many
single and dual-microphone SE ...
Multi-Channel Dynamic-Range Compression Techniques for Hearing Devices
(2018-08)
Dynamic-range compression (DRC) is an important component in hearing aid devices (HADs).
Research of multi-channel DRC design and real-time implementation has been carried out in the
last few decades. The trade-offs of ...
Study of Real-Time Facial Expression Recognition on Noisy Images and Videos
(2018-12)
Automatic facial expression recognition (FER) and emotion recognition have aroused many
researchers’ interest in a variety of research fields because of an important role in human
centered interfaces and the advent of ...
