Neville Thiele has a long and distinguished career in electro-acoustics, loudspeaker design and sound and vision broadcasting. Neville authored a landmark paper in 1961 that gave scientific basis to the design of loudspeaker enclosures. This paper along with further work with Richard Small gave rise to the Thiele Small parameters, which have been adopted by textbooks as the basis of loudspeaker design for much of the last 40 years.

In 1968 and in 1992 he was awarded the Norman W.V. Hayes Medal of the Institution of Radio and Electronics Engineers Australia (IREE) for best paper published that year in the Institution's Proceedings. In 1976, he was invited by the Audio Engineering Society (AES) to lecture on loudspeaker design at a seminar at the University of Colorado, a convention and meetings of the AES throughout the United States. In 1994, he was awarded the Silver Medal of the AES for pioneering work in loudspeaker simulation. Neville is currently the Vice President - International for the AES.

He has published more than thirty papers on electro-acoustics, network theory, testing methods and sound and vision broadcasting. Some of his papers, notably on loudspeakers, television testing and coaxial cable equalization, have become accepted internationally as references on these topics, including origination of the Thiele-Small parameters for measuring and designing loudspeakers and the Total Difference-Frequency Distortion measurement of audio transmission and recording.

In 1991, he was appointed Honorary Visiting Fellow at the University of New South Wales, and since 1994 has been an Honorary Associate at the University of Sydney, where he teaches part-time in the Graduate Audio Program.

Mr. Thiele graduated with a Bachelor of Engineering (Mechanical and Electrical) in 1952, after five years of war service in infantry and in A.E.M.E. Joining E.M.I. (Australia) Ltd, he was employed as a design engineer on special projects, including telemetry. With the start of television in Australia, he spent six months of 1955 in the laboratories of EMI at Hayes, Middlesex and associated companies in Scandinavia and America. Upon his return to Australia, he led the design team that developed EMI's earliest Australian television receivers. He was appointed Advanced Development Engineer in 1957, and was responsible for applying advanced technology in EMI Australia's radio and television receivers and electronic test equipment.

He is at present a consulting engineer in the fields of Audio, Radio, Television and Electronic Filter Design. He has a long association with Whise®, including the origination of the Neville Thiele Method (NTM) for crossover filters in Whise® products and licensed to BSS Audio.
