INVITATION to the lecture on "Sound Quality of Audio Systems" 

A lecture series on Electro-Acoustic will be presented by Prof. Dr. Wolfgang Klippel, Institute of Acoustics and Speech Communication, Dresden University of Technology, Germany.

This series consists of three parts:

PART 1: Basic Modeling (lumped and distributed parameters, linear, lonlinear, thermal, perceptive, ...)
PART 2: Measurement (Sound Quality Assessment)
PART 3: Electrical Control (linearization, protection, 3D-Sound, ...)

PART 2 "Measurement (Sound Quality Assessment)" will be the main topic of the next lecture taking place from March 11th to March 13th, 2013.

The lecture, presented as a block seminar, addresses the evaluation of sound reproduction systems using physical and perceptive measurement techniques. The generation of signal distortion is modeled by linear, nonlinear and time-variant systems with lumped and distributed parameters. New measurement techniques based on those models are presented using test signals and music as well. The course makes the relationship between symptoms and physical causes of the distortion more transparent and discusses the impact on the perceived sound quality by combining listening tests, auralization techniques with physical methods. This knowledge is important for defining target performance, designing small, light and cost-effective loudspeakers reproducing the sound at high efficiency and sufficient sound quality and for quality control in manufacturing. The new methods and diagnostic tools are illustrated on loudspeakers used in telecommunication, automotive, multi-media and professional applications. The lecture is supplemented by practical sections giving each participant further opportunities for learning by doing.
 
NEW TOPICS addressed in 2013: 
 Differential auralization technique to evaluate rub & buzz and other loudspeaker defects
 Holographic methods for assessing the near-field of personal portable audio devices
 Large Signal performance of balanced armature transducer 
 Automatic defect classification in audio devices using cluster analysis 
 New standard for output based assessment of active loudspeaker systems
 Transforming R&D specifications into production limits
