1. Design Investigation of Passive Radiators in Loudspeakers
Master-uppsats, Lunds universitet/InnovationSammanfattning : 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
2. Prototypmetoder för hornhögtalare
Master-uppsats, Lunds universitet/InnovationSammanfattning : 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
3. Extraction of Loudspeaker- and room impulse responses under overlapping conditions
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och systemSammanfattning : 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.

4. A Numerical Approach for Wind Tunnel Noise Control
Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWLSammanfattning : 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
