  1. 1. Squeak and Rattle Prediction for Robust Product Development

    Författare :Mohsen Bayani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; simulation; product development; squeak and rattle; sound quality;

    Sammanfattning : Squeak and rattle are nonstationary, irregular and impulsive sounds that happen inside the car cabin. For decades, customer complaints about squeak and rattle have been, and still are, among the top quality issues in the automotive industry. LÄS MER

  3. 2. Annoyance, quality- and safety aspects of sound in truck cabins

    Författare :Anders Genell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral balance; low frequency; product sound quality; annoyance;

    Sammanfattning : For heavy vehicles the interior sound environment is still more or less just apassive result of the engineering of the different parts that make up the vehicle,although measures are taken to keep sound pressure level within legislatedboundaries. Additionally, the sound inside truck cabins is dominated by itslow frequency (LF) content, and is hence prone to impair task performance andreduce wakefulness as well as cause general annoyance and different adversehealth effects.

  4. 3. Methods for product sound design

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

    Sammanfattning : Product sound design has received much attention in recent years. This has created a need to develop and validate tools for developing product sound specifications. LÄS MER

  5. 4. Squeak and Rattle Prediction for Robust Product Development in the automotive industry

    Sammanfattning : Squeak and rattle are nonstationary, irregular, and impulsive sounds that are audible inside the car cabin. For decades, customer complaints about squeak and rattle have been, and still are, among the top quality issues in the automotive industry. LÄS MER

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

    Författare :Daniel Västfjäll; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
