Comprehensive Transducer Testing in 24 Minutes

This article illustrates how the latest Klippel Multi-Scanning Workbench solution allows measurements across several domains (acoustical, mechanical, electrical, and magnetic) while working from non-anechoic environments. The author uses a practical characterization of balanced mode radiator (BMR) loudspeakers, which require a more complex approach when compared to conventional cone-based woofers or dome-tweeters. This article was originally published in Voice Coil, May 2021.

Quantifying Acoustic Sources Through Sound Power Measurement - White Paper Available

Andrew Barnard, Ph.D., INCE Board Certified from The Pennsylvania State University, touches on the basic source-path-receiver paradigm for white goods sound generation, focusing on the source in his latest research article. Understanding the source-path-receiver model is becoming increasingly important when determining proper measurement techniques for white goods noise radiation. With easy access to white goods data, consumers are more educated than ever on making their purchasing decision.
