    Sammanfattning : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. LÄS MER

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

    Magister-uppsats, Jönköping University/JTH, Industridesign

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

    Sammanfattning : 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. LÄS MER

  4. 23. Akustisk eller digital orkester? : En undersökning om hörbara skillnader mellan akustisk och digital orkester och vilken som föredras

    Kandidat-uppsats, Högskolan Dalarna/Institutionen för kultur och samhälle

    Författare :Denniz Nordin; [2023]
    Nyckelord :akustisk orkester; digital orkester; dynamik; mixning; trovärdighet; rumsklang; stereobredd;

    Sammanfattning : I denna studie undersöks skillnader mellan akustisk och digital orkester och vilken versionden allmänna lyssnaren utan särskilda musikproduktionsförkunskaper föredrar. Studien utgårfrån den digitala versionens perspektiv och fokuserar på hur en digital orkester kan redigerasför att låta akustisk. LÄS MER

  5. 24. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Alice Fracchia; [2023]

    Sammanfattning : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. LÄS MER

  7. 25. Prediction of Reverberation Time in Office Spaces by Investigation of the Scattering Factor in Odeon

    Master-uppsats, KTH/Teknisk akustik

    Författare :Viktor Söderlund; [2023]
    Nyckelord :Scattering Factor; Reverberation Time; Odeon; Sabine; Arau-Puchades; Spridningsfaktor; Efterklangstid; Odeon; Sabine; Arau-Puchades;

    Sammanfattning : Accurate estimations of the reverberation time of furnished office spacesis essential as an acoustic consultant. A time efficient way to predict thefurniture’s effect is to investigate it by software modelling. The room acousticsoftware Odeon is suitable for doing this. LÄS MER
