  1. 11. Measurement and Evaluation of Scattering Coefficient for Diffusing Panel

    Master-uppsats, KTH/Teknisk akustik

    Författare :Frida Ekner; [2023]
    Nyckelord :Mechanics; acoustics; scattering; Mekanik; akustik; spridning;

    Sammanfattning : In this work the aim was to determine the scattering coefficient for a diffusing panel by measurements and also examine the difference between scattering and diffusion. Similar measurements have been carried out in the past in slightly different ways, the method that was chosen was to follow a given standard for the measurement of the scattering coefficient.

  3. 12. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    Master-uppsats, KTH/Teknisk akustik

    Författare :Oscar Lundin; [2022]
    Nyckelord :Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Sammanfattning : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. LÄS MER

  4. 13. Variable acoustics in multi-functional stadiums

    Master-uppsats, KTH/Teknisk akustik

    Författare :Felix Vernersson; [2022]
    Nyckelord :Variable acoustics; Reflections; Gain; Reverberation; Clarity; Frequency masking; Perception of reflected sounds; Variabel akustik; Reflektioner; Rumsförstärkning; Efterklang; Klarhet; Frekvensmaskering; Uppfattning av reflekterade ljud;

    Sammanfattning : This paper handles the background theory, methods and results of the master thesis project titled "Variable acoustics in multi-functional stadiums". \\ The purpose of the project was to investigate whether variable room acoustics could be applicable to large multi-functional stadiums to improve their ability to adapt the soundscape in the stadium for different types of events.

  5. 14. 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.

  7. 15. 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
