The spectrum of tasks not only covers the vast area of the manifold auditive impressions in daily life, but also applications of ultrasound whose frequencies are far beyond the range of audibility of the human ear. It is the aim of the department's work to perform scientific basic research concerning the realization of the acoustic units, and to contribute to the improvement of living conditions by developing methods of measurement, testing acoustic measurement devices, and cooperating in the drawing-up of standards and regulations.
