1. Low Complexity Beamformer structures for application in Hearing Aids
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : Background noise is particularly damaging to speech intelligibility for people with hearing loss. The problem of reducing noise in hearing aids is one of great importance and great difficulty. Over the years, many solutions and different algorithms have been implemented in order to provide the optimal solution to the problem. LÄS MER
2. Real-Time Multiple Audio Beamforming System
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : The Cocktail party problem is a known problem within audiology and relates to a person’s ability to understand and separate speech from a noisy background with multiple speakers. This master’s thesis, in collaboration with Eriksholm Research Center, part of the company Oticon, developed a real-time system to help people with Hearing Impairment (HI) handle this problem by using a microphone array and a Minimum Variance Distortionless Response (MVDR) beamformer.

3. Array Element Localisation
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Abstract—This article have been written in cooperation with The Swedish Defense Research Agency (FOI). The article proposes a method to calibrate hydrophone positions for improved underwater survailence in The Baltic Sea. LÄS MER
4. BEAMFORMING TECHNIQUES USING CONVEX OPTIMIZATION
Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : The thesis analyses and validates Beamforming methods using Convex Optimization. CVX which is a Matlab supported tool for convex optimization has been used to develop this concept. LÄS MER
5. Integrated Speech Enhancement Technique for Hands-free Mobile Phones
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : This thesis investigates the systems for hands-free mobile communication. In hands-free communication, there are various kinds of disturbances in the microphone reception due to the distance between the source and the receiver. The disturbances are mainly background noise and reverberation. LÄS MER
