  1. 1. 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. 2. 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.

  6. 5. Integrated Speech Enhancement Technique for Hands-free Mobile Phones

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : ANEESH KALUVA; [2013]
    Keywords : Beamformer; Speech enhancement; Hands-free communication; Spectral subtraction; anechoic; Noise suppression;

    Abstract : 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. READ MORE
