  1. 1. A comparison of binaural recordings performed in six different room configurations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Denice Perkhed; [2021]
    Nyckelord :Binaural recordings; absorbtion coefficient; reverberation time; anechoic chamber; listening test; Psychoacoustics; Technology and Engineering;

    Sammanfattning : Children in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. LÄS MER

  2. 2. A General Approach to Inaudible Adversarial Perturbations in a Black-box Setting

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

    Författare :Johan Sörell; [2021]
    Nyckelord :;

    Sammanfattning : Deep learning is currently being deployed in many speech recognition systems. While these systems can achieve state-of-the-art performance, they are known to be susceptible to adversarial perturbations. These are minor perturbations to the input data, crafted specifically to cause erroneous behavior from the system. LÄS MER

  3. 3. Exploring Urban Soundscapes

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Kristin Nedlich; [2020]
    Nyckelord :Architecture; urban; environment; sound; psychoacoustics; exploration; Arts and Architecture;

    Sammanfattning : My intent with this thesis is to explore urban sound and architectural drawing techniques which can be used to represent sound qualities in existing or projected areas. By using experiential data, I will investigate methods and various sets of diagrams and drawings to illustrate psychoacoustical qualities in urban environments... LÄS MER

  4. 4. An indicative case-control study of noise perception due to environmental noise sources

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Marcus Johansson ; [2020]
    Nyckelord :Noise perception; Psychoacoustics; Environmental noise; Bullerpåverkan; Psykoakustik; Samhällsbuller;

    Sammanfattning : The subject of the thesis was proposed by the acoustic consultancy firm Brekke & Strand, which is of relevance for their additional understanding and development of services and contribution to robust solutions. The aim with this thesis is to give indicative results and to dig deeper into the relation between environmental noise and the perception of the same, specially focusing on construction related noise but also permanent noise sources that originates from infrastructure.

  5. 5. Evaluation of outdoor environment in preschools using the soundscape approach

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Teknisk akustik

    Författare :Semir Caban; [2020]
    Nyckelord :Soundscape; statistical analysis; psychoacoustics; outdoor sound environment; sound environment in preschools.; Technology and Engineering;

    Sammanfattning : Exposure to high levels of noise may affect a person’s health and behavior. A lot of education in Swedish preschool occurs outdoor, which makes having good sound environment important for the children and the teachers. LÄS MER
