Expert tip

Joachim Egelhof, Technical manager:
"Why are our SILENT extractors so quiet? Some noises are more stressful than others. We  worked with psychoacousticians who  showed us the unpleasant frequency ranges. This allowed us to minimize the noises drastically in this frequency range and provide the units with a pleasant audio frequency."
