    Sammanfattning : The aim for this thesis is to investigate and explore how to build more sustainably with wood. The understanding of climate change has in this day and age become a social and development issue. LÄS MER

  3. 27. Ingjutna ventilationskanalers påverkan på luftljudsisolering i flerbostadshus

    Kandidat-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Emma Näslund; [2022]
    Nyckelord :;

    Sammanfattning : Good sound insulation is highly valued by Swedish tenants. To be able to achieve that, one must look at many aspects, such as room volumes, floor planes, flooring, but also what materials that are to be built with and how it ́s constructed.  The use of cast-in ventilation ducts in the load-bearing structures is a common method in Sweden.

  4. 28. ROOM MAPPING FOR TUNING OF HIGH FIDELITY SOUND SYSTEMS

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Nabaz Sherif; Nils Sundelius; [2022]
    Nyckelord :;

    Sammanfattning : Using autonomous drones for positioning and tuning speakers in a room, could give the owners of the speakers a better and more personalized sound experience, if the speakers are tuned for the environment. As a first step towards that goal this project investigated methods that could use data gathered from a Crazyflie drone to identify interesting acoustic properties of a room. LÄS MER

  5. 29. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Elina Arvidsson; [2022]
    Nyckelord :Esrange Space Centre; Flame deflector; Acoustic estimation; Liquid rocket engine; Rocket Factory Augsburg; Jet acoustics; Esrange Space Centre; Flammdeflektor; Akustisk estimering; vätskedriven raketmotor; Rocket Factory Augsburg; strömningsakustik;

    Sammanfattning : The noise of a rocket engine is a complex and complicated phenomenon which has been studied for more than half a century [1]. There are many sources to this noise, but due to its great potential impact to the surrounding structures, including the vehicle itself, it is important to have a model to estimate the acoustic environment the engine produces.

  7. 30. Bild och akustik : Klassrummets ljudlandskap

    Uppsats för yrkesexamina på avancerad nivå, Konstfack/IBIS - Institutionen för bild- och slöjdpedagogik

    Författare :Emma Jansson; [2022]
    Nyckelord :Bildsalen; ljud; akustik; trygghet; koncentration;

    Sammanfattning : Around Sweden there are thousands and thousands of classrooms, and the majority of those classrooms adapt after the subject and what practice that is taking place within the space. In my experience (both during and before Konstfack) where I could find a classroom where art practice is taking place, the space tends to expand. LÄS MER
