Advice
The shaping and positioning of the material is of major importance to achieve an optimal sound-dampening effect. Sontech has long experience of practical noise control projects in a wide range of industrial fields. These experiences can be a valuable addition to the laboratory data given in the datasheet. Sontech can also assist with advice and sound measurements for noise control and in the manufacture of customised material sets.
