  1. 1. Design Investigation of Passive Radiators in Loudspeakers

    Master-uppsats, Lunds universitet/Innovation

    Författare :Fabrice Dufberg; Valter Hamberger; [2024]
    Nyckelord :passive radiator; loudspeaker; speaker tuning; Thiele Small parameters; frequency response; Technology and Engineering;

    Sammanfattning : Passive radiators are components that can be integrated into loudspeakers to amplify the bass frequencies. To ensure good sound quality, the passive radiator, the speaker driver, and the loudspeaker enclosure must all be well-dimensioned and fine-tuned in relation to each other. LÄS MER

  3. 2. Prototypmetoder för hornhögtalare

    Master-uppsats, Lunds universitet/Innovation

    Författare :Linn Andersson; Alice Nivestam; [2022]
    Nyckelord :prototyping; additive manufacturing; horn loudspeakers; acoustics; mechanical engineering; Technology and Engineering;

    Sammanfattning : The aim of this project was to investigate suitable prototyping methods to be used during the development of horn loudspeakers. Different methods were tested to investigate how well they replicated the original loudspeaker based on acoustical performance. LÄS MER

  4. 3. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Felix Gustafsson; [2022]
    Nyckelord :Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Sammanfattning : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

  5. 4. A Numerical Approach for Wind Tunnel Noise Control

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Hampus Dall; Robert Palm; [2021]
    Nyckelord :Technical Acoustics; ANC; Active Noise Control; Superposition; Wind Tunnel; Wingsuit; Indoor Wingsuit; Higher Order Modal Acoustic Field Beyond Plane Wave Region; Numerical Acoustic Simulations; Teknisk Akustik; Aktiv Brusreducering; Superposition; Vindtunnel; Flygning med ekorrdräkt inomhus; Högre ordningens akustisk modanalys bortom planvågsteori; Numeriska akustiska simuleringar;

    Sammanfattning : A wind tunnel from the 1950s located in Bromma, Stockholm, once used for military research is today used for commercial activities. Today the tunnel is used for indoor wingsuit flight and the facility has an interest in reducing the overall noise generated by the tunnel. Acoustic measurements indicate noise problems in the 50 Hz range. LÄS MER
