  1. 1. Simulation of low frequency acoustic waves in small rooms : An SBP-SAT approach to solving the time dependent acoustic wave equation in three dimensions

    University essay from

    Author : Alva Fährlin; Olle Edgren Schüllerqvist; [2023]
    Keywords : room acoustics; numerical methods; SBP; SAT; acoustic wave equation.;

    Abstract : Low frequency acoustic room behaviour can be approximated using numerical methods. Traditionally, music studio control rooms are built with complex geometries, making their eigenmodes difficult to predict mathematically. READ MORE

  3. 2. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.

    University essay from KTH/Tillämpad fysik

    Author : Abel Hugot; [2022]
    Keywords : Hybrid quantum systems; Acoustics; Impedance matching; SQUIDs; Hybrida kvantsystem; Akustik; Impedansanpassning; SQUIDs.;

    Abstract : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. READ MORE

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

    University essay from KTH/Teknisk akustik

    Author : Oscar Lundin; [2022]
    Keywords : 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.;

    Abstract : 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. READ MORE

  5. 4. Self-reported voice symptoms and voice handicap during virtual teaching compared to face-to-face teaching : A survey-based study on Swedish teachers in high schools and institutions of higher education

    University essay from Uppsala universitet/Blom Johansson: Logopedi

    Author : Maria Allebeck; Olivia Åberg; [2022]
    Keywords : Voice disorders; Work environment; School teachers; Distance learning; COVID-19; Röststörningar; Arbetsmiljö; Skollärare; Distansutbildning; Covid-19;

    Abstract : Purpose: Since the beginning of 2020, teachers all over the world have had to switch over to virtual teaching because of the COVID-19 pandemic. This change of teaching mode has unknown consequences on the vocal health of teachers. READ MORE

  6. 5. Improving bright-field images for tracking particles with Defocustracker

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Carl Lundin; [2022]
    Keywords : Defocustracker; GDPT; particle tracking; bright-field; acoustophoresis; Laplacian of Gaussian; Technology and Engineering;

    Abstract : Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. READ MORE
