  1. 1. Despeckling Echocardiograms Using Generative Adversarial Networks

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Falk DIppel; [2023-10-23]
    Nyckelord :Generative adversarial network; deep learning; echocardiography; speckle noise; denoising; segmentation;

    Sammanfattning : Previous research had shown that generative adversarial networks (GANs) are capable of despeckling echocardiograms (echos) through image-to-image translation in real-time once trained. However, only limited information regarding the quality of denoised echos and explainability of useful GAN components is provided. LÄS MER

  3. 2. Speech Enhancement in Hands-Free Device (Hearing Aid) with emphasis on Elko's Beamformer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :TELAGAREDDI S N U V RAMESH; [2012]
    Nyckelord :Speech Enhancement; Speech intelligibility; Speech Communication and Beamforming ;

    Sammanfattning : In general, an uncontrolled environment may contain degradation components like background noise, speech from other speakers etc. along with required speech components. It is very tough to concentrate only on speech signals in presence of background noise for normal listeners and hearing impaired persons. LÄS MER

  4. 3. Attention to the periphery attenuates the EPN and LPP

    Kandidat-uppsats, Psykologiska institutionen

    Författare :Elmeri Syrjänen; [2011]
    Nyckelord :Attention; Emotion; Motivation; ERP; EPN; LPP;

    Sammanfattning : Current research shows that emotions have an important role in guiding attention and cognitions especially when the emotional stimuli are affective. Load theory proposes that when the perceptual load on attention is sufficiently high, irrelevant emotional stimuli is no longer attended to and thus will not produce a distracting effect. LÄS MER

  5. 4. Från förnekande till integration. En kvalitativ studie av kvinnors förhållningssätt inför audiologisk rehabilitering.

    D-uppsats, Göteborgs universitet/Institutionen för neurovetenskap och fysiologi

    Författare :Torborg Arvidsson; [2009-02-10]
    Nyckelord :Förvärvad hörselskada; audiologi; audiologisk rehabilitering; kvinnor; fenomenografi; lärande; Aquired hearing loss; audiological rehabilitation; audiology; women; phenomenography; learning;

    Sammanfattning : Adjustment to acquired hearing loss can be understood as a process of learning and change where the point of departure is the subjective apppraisal of a person’s hearing loss in a social and cultural context. The aim of the study was to describe women’s thoughts, emotions and actions prior to audiological rehabilitation, since these are considered important for the ongoing process of adjustment and for the planning of rehabilitation.

  7. 5. Combining Acoustic Echo Cancellation and Suppression

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Fredrik Wallin; [2003]
    Nyckelord :Reglerteknik; acoustic echo cancellation; acoustic echo suppression; hybrid system; subjective listening tests; PESQ; perception; Reglerteknik;

    Sammanfattning : The acoustic echo problem arises whenever there is acoustic coupling between a loudspeaker and a microphone, such as in a teleconference system. This problem is traditionally solved by using an acoustic echo canceler (AEC), which models the echo path with adaptive filters. LÄS MER
