The SLH sound power hemispheres, designed as an "all for one" solution for a wide range of measurement tasks, are among others a contribution to ensure the legal requirements for sound emission of industrial and consumer equipment and more.
Noise reduction is only one side of the coin. Product sound design for industrial products is equally important for comfort, well-being and, above all, safety.
Thus, consumer-oriented sound design is becoming increasingly important in product development.

The sound intensity probes SIS 194 3D allow a simultaneous sound intensity measurement at one point of a room in all three dimensions.
For this purpose an arrangement of three one-dimensional sound intensity probes is formed, thus all three axes of the microphone pairs cross in one point and are in a plane perpendicular in each case.
Each of those microphone pairs constitutes a one-dimensional sound intensity probe in conventional design.
