  1. 1. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Huong Nguyen; [2023]
    Nyckelord :Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

    Sammanfattning : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.

  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. Creative development of lightweight façade constructions in modular housing : The struggle to shut out the noise of the world

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Johan Albihn; [2022]
    Nyckelord :Acoustical engineering; façade wall construction; modular housing; traffic noise reduction; lightweight construction; industrial design engineering; Akustik; fasadväggkonstruktion; modulhus; reducering av trafikbuller; lättviktskonstruktion; teknisk design;

    Sammanfattning : Modular construction of housing is an industry on the rise. The prefabrication of construction modules gives a greater control over material consumption, promotes standardization, and lessens the disturbance during the construction time in the field. Lindbäcks Bygg AB prefabricates housing modules in their factory at Haraholmen, Piteå. LÄS MER
