Sound level meter KS-125 Klimatherm
Sound simulator FSG-50 Klimatherm

Noise is not only a burden, it can also cause health damage. Already at 45 dB, a relaxed conversation is more difficult, with more than 65 dB of external load, the windows are kept closed and balconies can no be used to stay. The minimum requirements for sound insulation in buildings were compiled in DIN 4109 (sound insulation in building construction).

The soundproofing properties of a component or a room can be measured with the sound simulator and sound level meter. Using the sound simulator, different frequencies are simulated. The resulting noise stress is measured with the sound level meter.
