  1. 6. Drum sound from floor coverings - objective and subjective assessment

    Författare :Ann-Charlotte Johansson; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; hydraulik; Maskinteknik; vacuum technology; vibration and acoustic engineering; hydraulics; acoustic standard; Mechanical engineering; tapping machine; veneer flooring; parquet flooring; binaural recording; foot impact; loudness; sound quality; listening test; paired comparisons; walking sound; drum sound; building acoustics; psychoacoustics; laminate flooring;

    Sammanfattning : Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound.

  3. 7. Factors Governing Acoustical Comfort In Vehicle Compartments

    Författare :Oliver Jung; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driving Noise; Lombard Effect; Sound Quality; Psychoacoustics; Acoustical Comfort; Emotions; Vehicle Acoustics; Speech Communication; Cognition Psychology; Speech Quality;

    Sammanfattning : A pleasant interior sound field is an essential comfort criterion for vehicle occupants.The pleasantness is mainly influenced by a low overall sound pressurelevel. Further minimization of driving noise, however, is constricted on thelower end by physical limitations. LÄS MER

  4. 8. Hearing in increasing age. Epidemiological and psychoacoustic aspects

    Författare :Radoslava Jönsson; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 9. Perceptually motivated speech recognition and mispronunciation detection

    Författare :Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

    Sammanfattning : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. LÄS MER

  7. 10. Sound perception and design in multimodal environments

    Författare :PerMagnus Lindborg; Anders K. Friberg; Daniel Västfjäll; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sound; perception; design; multimodal; environment; soundscape; music; listening; crossmodal; psychoacoustics; psychophysiology; personality trait; emotion; appraisal; aesthetics; colour; correlation; regression; classification; sonification; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of  methods, and integration of science and art. LÄS MER
