  1. 1. Acoustic perception of Metal live performance in a multipurpose hall (Black Box) : A study into the influence of the acoustical quality of a Black Box regarding Metal live performance.

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

    Författare :Sam Soliman; [2023]
    Nyckelord :Metal; room acoustics; influence; live performance; parameters; acoustics;

    Sammanfattning : A study has been implemented regarding the acoustical characteristics of a black box and its influence on rock and metal music live performance. Objective acoustical measurements have been made as well as a subjective evaluation in form of a listening test. LÄS MER

  3. 2. Room Impulse Response Interpolation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Daníel Thor Wilcox; [2023]
    Nyckelord :Virtual Acoustics; Machine Learning; Signal Processing; Room Impulse Response; Virtuell Akustik; Maskininlärning; Signalbehandling; rumsimpulssvar;

    Sammanfattning : In Virtual Reality (VR) systems, the incorporation of acoustics allows for the generation of audio-visual stimuli, facilitating applications in engineering, architecture, and design. The goal of virtual acoustics is to create a realistic sound field in continuous space. LÄS MER

  4. 3. Speckle suppression in ultrasound images of heterogeneous materials

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Simon Johnsson; [2023]
    Nyckelord :Ultrasound; non-destructive testing; wiener filter; signal processing;

    Sammanfattning : Performing non-destructive testing (NDT) on materials is a helpful tool for maintenance and quality control because the materials are not destroyed or disturbed; ultrasound imaging is one type of NDT. Ultrasound imaging of heterogeneous materials contains many echoes from the material itself. LÄS MER

  5. 4. Market for Reuse - Investigating reuse of acoustic ceilings from a market perspective

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Oscar Nilsson; Anton Gunnarsson; [2023]
    Nyckelord :Green Building Certifications; Circular Economy; Circular Logistics; Circular Marketing; Construction Product Regulation; Management; Reuse; Reverse Logistics; Technology and Engineering;

    Sammanfattning : Context: Today, 96% of Sweden’s materials come from virgin resources and only 3.4% of resources used in Sweden are retained in the value chain. From a total of 266 million tonnes fed into the economy each year, 46.9% consist of construction materials. LÄS MER

  7. 5. The effect of age and different speech tasks on the Acoustic Voice Quality Index

    Magister-uppsats, Umeå universitet/Logopedi

    Författare :Rosanna Rehn; [2023]
    Nyckelord :AVQI; acoustic voice quality index - acoustic evaluation - overall voice quality - multiparametric voice assessment - sustained vowel - continuous speech;

    Sammanfattning : Background Previous research has emphasized the importance of objectivity in voice quality evaluation. Acoustic voice quality index (AVQI) is a multiparametric objective index, that quantifies overall voice quality. Over the past decade, international studies have demonstrated strong diagnostic accuracy and sensitivity of AVQI to voice disorders. LÄS MER
