3D-printed Acoustic Directional Couplers
(2014)Acoustic Directional Couplers permit separation of forward and reverse sound pressure waves. This separation opens the way to traceable precision acoustic reflection measurements. In order to span the audio frequency range, ... -
A calibrated dual-port acoustic Vector Network Analyser
(The University of Waikato, 2022)The Vector Network Analyzer (VNA) is a workhorse in electrical engineering, and has been refined over the last fifty years to offer many advantages. This technology is continually expanding and branching into other fields ... -
Development and Basic Calibration of an Acoustic Vector Network Analyser
(2017)This project aims to develop a method that drastically improves measurement of the acoustic properties of objects. Previously research at the University of Waikato has made progress with acoustic technologies as a precursor ... -
Full 2-port vector-corrected network analyzer in the acoustic domain
(Audio Engineering Society, 2022)This manuscript presents the theory and design of a Vector-corrected Network Analyzer (VNA) realized in the acoustic domain. This is a novel measurement instrument based on the established microwave vector network analyzer. ... -
Realizing an Acoustic Vector Network Analyser
(2019)Acoustic absorption, reflection, and transmission is typically measured using an impedance tube. We present the design and initial measurements of a radically different measurement system. The instrument builds on the rich ...
