  2. 2. Comparative research in Room Acoustics Simulation Software

    University essay from Chalmers tekniska högskola/Institutionen för arkitektur och samhällsbyggnadsteknik

    Author : Neza Kravanja; [2018]
    Keywords : room acoustics; simulation; software; acoustic parameters; Odeon Audi-torium; CATT-Acoustics;

    Abstract : In rooms for speech and music, the suitable sound environment is one of the most important components of space design. Room Acoustics Simulation Software is often used to predict sound conditions in a non-existing room. However, the design process presents many unknowns such as the room geometry, settings, and materials. READ MORE

  3. 3. Development of Vessel Phantoms for Ultrasound Methods

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Benjamin Meirza; [2018]
    Keywords : Longitudinal movement of the arterial wall; Vasa vasourom; Micro vessles; SEBS; Ultrasound phantom.; Technology and Engineering;

    Abstract : Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation.

  4. 4. Enrichment of microparticles in droplets using acoustophoresis

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Klara Björnander Rahimi; [2018]
    Keywords : droplet microfluidics; acoustophoresis;

    Abstract : Acoustophoresis is a label free method where the acoustic radiation force is used to manipulate microparticles inside microfluidic channels. The magnitude of the force is dependent of several parameters, which include the density, speed of sound and size of the microparticles, as well as the amplitude of the pressure waves. READ MORE

  5. 5. Development of a general acoustic model for an arbitrary surveillance camera design

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Shenyang Fei; [2018]
    Keywords : MEMS microphone; Frequency Response; Thermoviscous Losses;

    Abstract : This thesis studies how the mechanical design of a surveillance camera affects the acoustic performance, mainly in terms of the frequency response within the human hearing range. During the project, the mechanical characteristics that affect frequency response were investigated by measuring the camera’s audio behavior in an anechoic chamber. READ MORE
