  1. 1. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Luke Postema; Johan Davidsson; [2019]
    Keywords : Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

    Abstract : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. READ MORE

  2. 2. Low Complexity Beamformer structures for application in Hearing Aids

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Eleni Koutrouli; [2018]
    Keywords : hearing aids; beamformers; MVDR algorithm; microphone arrays;

    Abstract : 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. READ MORE

  3. 3. Real-Time Multiple Audio Beamforming System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Johan Lindqvist; Martin Sollenberg; [2018]
    Keywords : Technology and Engineering;

    Abstract : 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.
