Impact sound insulation compared.

For the first time, DIN 7396 describes clear test conditions for measuring the acoustic properties of impact soundproofing elements. Tests are performed on common staircase geometries and under the loads usually occurring in buildings. The characteristic values specified in DIN 7396 can be used for soundproofing certification according to DIN 4109. All Schöck Tronsole® types have been tested using this procedure.

Schöck Elodur®

Schöck Elodur® is an elastomer support that was developed specifically for impact sound insulation. It is the key component in Schöck Tronsole®. Unlike conventional impact sound insulation supports, Schöck Tronsole® achieves an improvement of about 10 dB in impact sound insulation performance by using the elastomer support, Schöck Elodur®. This is approximately equivalent to about half the perceived loudness level.
