The paper, titled A Practical Comparison of Three Tetrahedral Ambisonic Microphones, discusses the microphones (an experimental microphone, a Sound Core TetraMic, and either a Soundfield MkV or SPS422B) and equipment chosen to make these recordings and the results of two listener surveys, each comparing segments of different recordings made simultaneously with the three microphones. Listeners were asked to play the recordings in a location and on equipment with which each was familiar. Typically, that was their home audio system. The survey was not an attempt to determine which microphone was "the best," rather, to gather critical subjective analysis about what they heard, or did not hear, from the different microphones. The survey respondents concluded that the experimental mic and Soundfield tied as "favorites."

Hard copies of the paper were available for distribution at the AES Convention in Munich. The paper is currently available online and via download as a pdf. Click AES_126_7676 to view or download the paper.
