The initiatory description of the physical nature of sound leads to the specific characteristics of low-frequency and especially infrasound. Findings about perception and threshold are discussed for low-frequency and infrasound. In an excursus on the almost 100 year old history of infrasound research the range of applications, technical developments and aims are presented. Methods and results of the experimental research on the physiological effects of infrasound are summarized for the last 50

The problem of lacking systematization in infrasound research is taken on and enriched with some progressive ideas. In addition to evaluation of the scientific errors in research effective methods for production, measurement and weighting of very low-frequency sound as well as the need for further research are presented. Furthermore methodical problems of experimental research are illustrated and proposals on improvement made. Even after a hundred years infrasound research has by no means come to an end as it constantly has to deal with new needs in the steadily changing living environment. In the bottom line of this paper the future of research on infrasound and low frequency noise is seen in education and prevention of noise pollution.
