Neville Thiele

Biography

For more than 40 years, Neville Thiele's and Richard Small's Thiele-Small (TS) parameters have been the de facto criteria for assessing the performance of loudspeakers. Their unified approach analyzes the electromechanical behavior of a speaker's components and the interaction with each other and with the air inside and outside the speaker cabinet. The resulting equation is mathematically identical to that describing a circuit. Then, sound produced by the speaker can be calculated by a simple circuit analysis. By using the TS parameters in computer models, users could design the loudspeaker/cabinet interface without having to manually build a speaker cabinet.

Neville Thiele worked at EMI Australia Ltd. for 10 years designing consumer audio radio and video equipment, and with the Australian Broadcasting Corporation for 23 years, designing and assessing equipment and systems for sound and television broadcasting. His honors include the Institution of Radio and Electronics Engineers Australia's Norman W.V. Hayes Medals for best papers and its Award of Honour, as well as the Silver Medal of the Audio Engineering Society (AES). He is a member of the Society of Motion Picture and Television Engineers and a Fellow of the Institution of Engineers Australia and the AES Mr. Thiele is an active member of the ITU-R's Australian National Study Group and Standards Australia's committee on digital audio and video.
