  1. 1. Solving Partial Differential Equations With Neural Networks

    Master-uppsats, Uppsala universitet/Matematiska institutionen

    Författare :Håkan Karlsson Faronius; [2023]
    Nyckelord :Partial differential equations; neural networks; physics-informed neural networks; deep ritz method; fourier neural operator; importance sampling; inverse problems;

    Sammanfattning : In this thesis three different approaches for solving partial differential equa-tions with neural networks will be explored; namely Physics-Informed NeuralNetworks, Fourier Neural Operators and the Deep Ritz method. Physics-Informed Neural Networks and the Deep Ritz Method are unsupervised machine learning methods, while the Fourier Neural Operator is a supervised method. LÄS MER

  3. 2. Music Preferences, Perceived Loudness, and Preferred Listening Levels : An investigation of sound level preferences for live sound reinforcement in Swedish free churches

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Petrus Ericson; [2022]
    Nyckelord :Sound levels; live sound reinforcement; loudness; music preference; hearing impairments; sound level tolerance; church; congregation; mix philosophy; sound balance; role of sound; worship; worship music; Ljudvolym; ljudstyrka; musikpreferens; hörselskada; balans; kyrka; lovsång; kyrkomusik; församling; Pingstkyrkan;

    Sammanfattning : Sound levels in live sound reinforcement have long been a topic for debate in live concerts, but the subject is also important elsewhere. Swedish Christian free churches have also struggled for many years to optimize how sound reinforcement can serve the community. LÄS MER

  4. 3. An investigation into outside factors effect on ANC headphone performance

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Andreas Grahn; Eddie Lindgren; [2022]
    Nyckelord :ANC; ANC headphones; experiments; performance; reliability; quality testing;

    Sammanfattning : In the current studied literature there is a lack of data and documentation on how outside factors affect the performance of ANC headphones. The purpose of this thesis is to investigate how these factors affect ANC headphone performance. The investigation into these factors was done by gathering quantitative data with experiments.

  5. 4. Ljudmaskering i kontorslandskap : En studie om optimering av ljudmaskeringssystem

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Filip Garpensvärd; Anton Knutar; [2020]
    Nyckelord :;

    Sammanfattning : This thesis contains a study of how sound masking systems can be implemented in existing open-plan offices in order to lower the speech intelligibility. The purpose is to investigate how to optimize the sound pressure level and frequency response for a sound masking system. LÄS MER

  7. 5. The impact of onset transient duration onperceived transient loudness : Could transient level reduction be compensated by increasing transient duration?

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för konst, kommunikation och lärande

    Författare :Jakob Erlandsson; [2020]
    Nyckelord :Audio; Transient; Transient duration;

    Sammanfattning : When mixing and mastering modern music, many engineers strive for making the end product to be perceived as loud as possible without sacrificing audio quality. Achieving this will often involve reducing the dynamic range of a track through peak limiting. LÄS MER
