AN institute for the study of sound has just been established in Prague under the management of Profs. K. Teige, M. Seemen and V. Vojtech. The purpose of the institute will be to bring together scientific and practical workers to investigate sound in its physical, technical and physiological aspects. In pursuit of these aims it is proposed to arrange inquiries, excursions, lectures, both scientific and popular, and to carry out experiments and publish the results. The first important step to be taken in this connexion will be the equipment of a research laboratory, and one of the first tasks of the institute will be to investigate noise and the methods of dealing with it. Another subject for early inquiry will be the technique of musical instruments.
