07_Test results of Skydas security class 3 double leaf door soundproofing

Our tests were carried out with the door installed in a wall that had 70 dB sound resistance. The test report for the SKYDAS STANDARD-3 double leaf door was 43 (-2; -7) dB. If your wall has less than 70 dB resistance your results may be from two to seven decibels worse.
