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

    Författare :Ann-Charlotte Johansson; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  2. 2. Communication quality : a conceptual approach focusing on classroom assistive listening devices

    Författare :Johan Odelius; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : In a classroom an assistive listening device (ALD) is a system of external microphones that transmit sound from a sound source directly to students' hearing aids. An ALD can be a microphone close to the mouth which transmits a voice directly to listeners' hearing aids. LÄS MER

  3. 3. Wearing Sound : Foundations of Sonic Design

    Författare :Vidmina Stasiulyte; Clemens Thornquist; Daniëlle Bruggeman; Högskolan i Borås; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Sammanfattning : Fashion is primarily a visual ontology consisting of definitions, theory and methods that are based on visual language. This research revises fashion by approaching it from a different—sonic—perspective wherein sound is considered not as a negative aspect but as a potential source of a new theory and facilitator of the evolution of new methods.

  5. 5. Affect as a Component of Perceived Sound and Vibration Quality in Aircraft

    Författare :Daniel Västfjäll; Chalmers University of Technology; []
    Nyckelord :comfort; sound quality; evaluations; affective reactions; preference; interior aircraft sounds; propeller aircraft;

    Sammanfattning : The concept of product sound quality is becoming an integral component of product development and design. The research presented in this thesis test the notion that affective reactions (i.e. positive-negative feelings) are a major determinant of perceived sound quality. LÄS MER
