  2. 1. Sound source localization from laser vibrometry recordings

    Author : Erik Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Acoustic holography deals with a typical inverse problem, to obtain the unknown from something that is known. From measurements of sound, most often using microphone arrays, reconstructions of the sound field are made in an attempt to find out what causes the sound. READ MORE

  4. 2. The psychophysics of human echolocation

    Author : Carlos Tirado Aldana; Mats Nilsson; Daniel Västfjäll; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Detection; Individual differences; Human echolocation; Lateralization; Localization; Echobot; Psychology; psykologi;

    Abstract : Echolocation is the capacity to detect, localize, discriminate, and, overall, gather spatial information from sound reflections. Since we began studying it in humans, we have learned several things. First, most humans can echolocate to some degree. READ MORE

  5. 3. Hearing in increasing age. Epidemiological and psychoacoustic aspects

    Author : Radoslava Jönsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aged; Aged; 80 and over; Audiometry; Demography; Ear; Epidemiology; Hearing; Presbycusis; Psychoacoustics; Questionnaires; Socioeconomic Factors; Sound Localization;

    Abstract : Presbyacusis, age-related hearing decline, is the most common cause of hearing impairment in the more developed countries. Planning of health services for the hearing impaired requires knowledge of hearing in increasing age and in demographic changes. READ MORE

  6. 4. Sound quality assessment using binaural technology

    Author : Donatas Trapenskas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : This licentiate thesis contains experimental work about the use of binaural technology for assessment of sound quality. Binaural technology aims to measure sound in the way compatible with human hearing. For that purpose artificial head with the microphones in the position of the ears is used. READ MORE

  7. 5. Minimal Problems and Applications in TOA and TDOA Localization

    Author : Simon Burgess; Mathematical Imaging Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Calibration-Free Localization; TOA; TDOA; RSSI Localization;

    Abstract : The central problem of this thesis is locating several sources and simultaneously locating the positions of the sensors. The measurements captured by the sensors are time of arrival (TOA), time difference of arrival (TDOA), unsynchronized TDOA, or received signal strength indication (RSSI), all a variation of distance measurement between sensors and sources.
