  1. 1. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesper Brunnström; [2021]
    Nyckelord :Active noise control; Secondary path modelling; Spatial; Adaptive filter; Multichannel; Least mean squares; Aktiv brusreducering; Sekundärvägsmodellering; Spatial; Adaptiv Filtrering; Multikanal; Minsta kvadratmetoden;

    Sammanfattning : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. LÄS MER

  3. 2. Sound Source Localization and Beamforming for Teleconferencing Solutions

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Angelica Kjellson; [2014]
    Nyckelord :statistical digital signal processing; microphone array signal processing; sound source localization SSL ; beamforming; uniform circular array UCA ; teleconferencing;

    Sammanfattning : In teleconferencing the audio quality is key to conducting successful meetings. The conference room setting imposes various challenges on the speech signal processing, such as noise and interfering signals, reverberation, or participants positioned far from the telephone unit.

  4. 3. Using your Smartphone as a Game Controller to your PC

    Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Marcus Löwegren; Rikard Johansson; [2013]
    Nyckelord :Game Controller; Natural Mapping; PC Game; Phone-Computer Interaction; Smartphone Game; Human-Computer Interaction; HCI;

    Sammanfattning : Many people in the world today own a smartphone. Smartphones of today usually have an advanced array of inputs in forms of tilting, touching and speaking, and outputs in forms of visual representation on the screen, vibration of the smartphone and speakers for sound. LÄS MER

  5. 4. Improved speech communication in a car

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Mårten Nygren; [2003]
    Nyckelord :Reglerteknik; Automobile; Speech enhancement; Microphone array; Communication; Bil; Tal förstärkning; Mikrofon array; Kommunikation; Reglerteknik;

    Sammanfattning : In modern cars a lot of effort is put on reducing the background noise level. Despite these efforts it is often difficult for persons in the rear seat(s) to hear the persons in the front seat. This is partly due to the background noise, but also geometry and acoustics properties of the passenger compartment. LÄS MER
