  1. 1. The development of an acoustic insulation solution using mushroom mycelium as an alternative to synthetic foams

    University essay from Jönköping University/JTH, Industridesign

    Author : Adrián Brito Guerrero de Escalante; [2023]
    Keywords : mycelium composites; design thinking; design for emotion; sustainability; acoustic insulation; fungi; mushrooms.;

    Abstract : In the past decades, humanity is facing the consequences of the irresponsible production of plastics and the expansion of industries such as industrial agriculture, Therefore, the development of new sustainable alternative materials has become increasingly popular as a science field. That is the case of mycelium composites, a biodegradable material made out of agricultural and the thread-like roots of mushrooms called mycelium. READ MORE

    Abstract : Insulation in rotating machines is a common cause for failure. Therefore, research in the area is large and is important to further increase the knowledge of the phenomena related to insulation degradation. READ MORE

  5. 4. Attenuation of fan noise with passive methods : An experimental study in the implementation of a ducted fan inside the body of a blended wing body UAV

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mustafa Kulbay; [2021]
    Keywords : ;

    Abstract : This report is about a novel approach to attenuation of fan noise in aerial vehicles, by way of implementing a ducted fan in the chassis of a four meter blended wing body plane. Three different one meter PVC pipes were used and their performances as silencers were tested by measuring the sound power level and calculating the insulation loss compared to a fan by itself.
