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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Elina Arvidsson; [2022]
    Keywords : 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;

    Abstract : 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.

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

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

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

    Abstract : 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. READ MORE

  4. 3. Designing a better soundscape for the home office : Devlopment of acoustic furniture

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Hanna Mattsson; Theodor Mihel; [2021]
    Keywords : Industrial design engineering; Human centered design; Acoustic design; Furniture design; Product development; Home office; Sound environment; Teknisk design; människocentrerad design; Akustisk design; Möbeldesign; Produktutveckling; Hemmakontor; Ljudmiljö;

    Abstract : As Covid-19 spread throughout the world in the early months of 2020 many people’s lives changed drastically. The situation forced millions of workers and students to start performing their work remotely from home. Currently in Sweden statistics shows that every third person working does it from home at least once a week. READ MORE

  5. 4. Characterization of Agarose Microdroplet Properties for Acoustic Trapping of Encapsulated Bacteria and On-chip DNA Extraction

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Tinde Höjer; [2021]
    Keywords : ;

    Abstract : The aim of this project was to investigate if the translation of a DNA extraction protocol to on-chip, for the purpose of reducing the total assay time, would be possible. This was to be enabled by encapsulating bacteria in hydrogel microdroplets that would then be acoustically trapped in a microfluidic system. READ MORE

  6. 5. Sonar Sea : The acoustic experience of the Baltic Sea dynamics

    University essay from Konstfack/Inredningsarkitektur & Möbeldesign

    Author : Elin Stampe; [2021]
