Wolfgang Klippel (Presenter)
This tutorial reports the development of new IEC standards addressing conventional and modern measurement techniques applicable to all kinds of transducers, active and passive loudspeakers and other sound reproduction systems. The first standard proposal describes important acoustical measurements for evaluating the generated sound field and signal distortion based on black-box modeling. The second standard is dedicated to the measurement of electrical and mechanical state variables (e.g. displacement), the identification of lumped and distributed parameters (e.g. T/S) and long-term testing to assess power handling, thermal capabilities, product reliability and climate impact. The tutorial gives a deeper insight into loudspeaker modeling, which is the basis for modern measurement techniques, and shows the practical relevance of this knowledge for transducer and system design.
This session is presented in association with the AES Technical Committee on Loudspeakers and Headphones
