  1. 1. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Bill Claesson; [2023]
    Nyckelord :;

    Sammanfattning : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. 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. Acoustic Characterization of Catalyst

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Surachit Dokson; [2023]
    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER

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

    Kandidat-uppsats,

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

    Sammanfattning : 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. LÄS MER

  7. 5. Buffer modification: A case study with polystyrene beads, DU145-, and MCF7 cell lines

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Olivia Hansson Rengbrandt; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Separation of cancer cells gives advantages in understanding the disease, guiding treatment decisions, and facilitating drug development. Overall, separation plays an important role in biological research. Acoustophoresis is a technique that utilizes acoustic waves to separate particles and cells suspended in a buffer medium. LÄS MER
