Noise-Robust Speech Source Localization and Tracking Using Microphone Arrays for Smartphone-Assisted Hearing Aid Devices
Speech Source Localization (SSL) (or Direction of Arrival estimation) is a powerful pre-processing tool that helps identify the direction of the talker of interest in a noisy environment using multiple fixed microphones ...
Smartphone-Based Single and Dual Microphone Speech Enhancement Algorithms for Hearing Study
Speech Enhancement (SE) is elemental in many real world applications. In the last two decades, extensive studies have been carried out on single and multi-channel SE techniques. In this thesis, three novel SE algorithms ...
Acoustic Feedback Cancellation Techniques for Hearing Aid Applications in Noisy Environments
Acoustic feedback cancellation is a problem of great interest to researchers in Hearing Aid Device (HAD) applications. Acoustic feedback effect arises due to the acoustic leakage from the loudspeaker to the input microphone. ...
FPGA System Design of a Cochlear Research Platform to Support Bimodal (EAS) and Variable Rate Electric Stimulation
The extensive research and continuous improvements in sound processing strategies play a significant role in the advancement of cochlear implants and hearing aid technologies. Cochlear implants are characterized by different ...
Development and Analysis of Real-Time Acoustic Feedback Cancellation and a Clinical Testing Simulator for Hearing Studies
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 ...
Dual Microphone Speech Enhancement Algorithms on Android-Based Devices for Hearing Study
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 ...
