  5. 4. Integrative Analyses of Perception and Reaction to Information and Warning Sounds in Vehicles

    Författare :Anders Sköld; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methods; Emotions; Physiological reactions; Mediation; Auditory Icons; Auditory Alerts; Sound Quality; MDU;

    Sammanfattning : The aim of the present thesis is to establish procedures to connect different types of data on auditory perception. This knowledge will lead to both a better understanding of perception in general, but also more efficient and cost effective methods for analyzing auditory perception data. LÄS MER

  7. 5. Perception of rolling noise

    Författare :Alice Hoffmann; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auralization; Rolling Noise; Perception; Tyre Road Noise; Psychoacoustics;

    Sammanfattning : Due to improvements on combustion-engines and electric-engines for cars, tyre noisehas become the prominent noise source at low and medium speeds. Models existthat simulate the noise produced by a rolling tyre, as do models that auralize differenttraffic situations from a basic data set. LÄS MER
