Short course on PSYCHOACOUSTICS AND QUALITY OF PRODUCTS |
Place: Room 1.09, Lisbon Congress Center Lecturers: Prof. Dr.-Ing. Klaus Genuit (HEAD acoustics GmbH) Timetable: 09:00 - 13:30 (30 min. break) Sound quality of various technical products has become very important. It is interpreted as among the most relevant factors regarding perceived product quality, and is important in gaining market advantage. Furthermore, it is increasingly acknowledged that environmental noise influences the quality of life. To cover this effect adequately conventional community noise concepts and methods are insufficient. Thus, soundscape approaches are needed to consider noise and its perception from a different point of view. A profound knowledge of psychoacoustics, human signal processing, and an understanding of product-user or environment-visitor relations is required to comprehend the perception and assessment of sound. Moreover, listening experiments as well as advanced acoustical analyses must be applied to “measure” the quality of sound adequately. The short course will give an overview of recent methods and analyses with respect to psychoacoustics, design of experiments and measurement technology in the scope of sound quality and soundscapes. Here, several methods and procedures are introduced which are frequently applied. In addition, new qualitative and explorative methods are introduced, which allow for a thorough, in-depth investigation of perceived sound quality. Some case studies will be presented to illustrate the benefits and limitations of different methods. Main Program Topics: Introduction to Sound Quality; Basics of Human Auditory Perception; Basics and Principles of Psychoacoustics; Realistic Recording and Reproduction of Sound; Jury Testing: Data Collection and Analysis of Data; Development of Sound Quality Metrics; Explorative, Qualitative Methods; Measurement of Soundscape; Benchmarking, Target Sound Development |
