马大猷先生长期从事物理声学和建筑声学研究工作。于1937年进入美国加州大学洛杉矶分校,在声学家努特森(Vern Oliver Knudsen)教授指导下开始科研生涯。1938年提出的简正频率分布定律是波动声学的基本定律之一。同年转入哈佛大学,师从韩特(Frederick Hunt)教授从事房间声场混响研究,与韩特、白瑞奈克(Leo Beranek)合作发表的论文《矩形房间中的声衰变分析》被声学界视为建筑声学发展的里程碑。他 Mr. Ma Dayu has long been engaged in physical acoustics and architectural acoustics research. He joined the University of California, Los Angeles in 1937 and began his research career under the direction of Professor Vern Oliver Knudsen. The law of normal frequency distribution proposed in 1938 is one of the basic laws of fluctuating acoustics. In the same year she moved to Harvard and studied under Professor Frederick Hunt’s room sound field reverb study. The paper “Analysis of Acoustic Decay in Rectangular Rooms,” in collaboration with Hante and Leo Beranek, was considered by the acoustic community to be A milestone in the development of architectural acoustics. he
