Per Vilhelm Brüel (March 6, 1915 – April 2, 2015) was a Danish physicist and engineer who pioneered and made fundamental contributions to the development of the physics of sound and vibration. He also formed and founded the world's largest manufacturer and supplier of sound and vibration measurement equipment, systems and solutions, Brüel & Kjær. Brüel was a close friend of Niels Bohr, and despite danger Brüel traveled from Sweden to Denmark during the German occupation with important documents of Bohr's work.〔Per Brüel: An Interview Conducted by Frederik Nebeker, Center for the History of Electrical Engineering, 18 July 1996.〕〔Mowry, and Borring (2012).

Brüel's father was a forester, a tradition that he intended his son to continue. However, Brüel did not like the idea of becoming a forester, causing a family scandal. The family lived in the South of Jutland, away from schools and towns. When Brüel got older, he was sent away for "blacksmith" education, which then denoted a practical education in engineering. But he decided to attend university and reallocated to the technical university in Copenhagen. There Brüel pursued aerodynamics, electronics, and acoustics.〔Per Brüel: An Interview Conducted by Frederik Nebeker, Center for the History of Electrical Engineering, 18 July 1996.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Per Vilhelm Brüel」の詳細全文を読む スポンサード リンク
