摘要
约150年前,亥姆霍兹用他发明的共鸣器在历史上第一次做了乐音和语音的频谱分析,并提出音乐理论和听觉理论,这是19世纪的重大科学贡献,亥姆霍兹共鸣器一直是频谱分析和选频接收、测量和控制的利器.理论上的发展更扩大了它的应用范围.单个共鸣器或共鸣器组合在乐器制造、厅堂建筑、噪声控制等方面都起很大作用.由共鸣器组合发展的穿孔板结构不仅在民用范围内起重要作用,在大型喷气飞机制造中也是不可替代的防止噪声污染的手段.本文对亥姆霍兹共鸣器的原理、应用和发展作一概述.
Some 150 years ago, Herrmann von Helmholtz, for the first time in the history, made frequency analysis of musical tones and speech sounds with the help of his newly-invented res-onators. The results were his theories of music and hearing-great contributions in the 19th century physics. Helmholtz resonators have always been the important tools in frequency analysis and in selective reception, measurement and control of sounds. Progress on the theo-retical understanding of Helmholtz resonator has enlarged Its usefulness. Individual res-onators and group of resonators are important in musical instrument manufacture. room acoustics and noise control. The preforated panel constructions, developed from the groups of resonators, are important in civilian use as well as indispensable to the noise pollution control in large jetliners. It is the purpose of the present article to review the principle, applications and development of the Helmholtz resonators.
