Abstract

In this interview organized through the Acoustical Society of America, Per Brüel discusses his life and career, focusing especially on his introduction to the field of acoustical instrumentation and his work in industry. It also discusses his association with ASA and other national acoustical societies. Brüel recalls his upbringing in Jutland, education at what is now called the Technical University of Denmark, experiences during World War II, early R&D work in Sweden, and his relationship with figures such as P. O. Pedersen and Viggo Kjær. He also discusses his work on architectural acoustics and the origins and successes of such Brüel & Kjær products as the constant percentage analyzer, level recorder, and condenser microphone, as well as his criticisms of the A-weighting curve used in noise measurement. He reflects on Brüel & Kjær management issues, including his division of responsibilities with Kjær, how they made decisions jointly, relations with universities, advertising, and the strategic decisions leading up to the sale of the company in 1992. The interview concludes with discussions of Brüel’s interest in cars and flying, his family, and his activities following the sale of Brüel & Kjær.
