02_Double leaf door installed ready for soundproofing test

The SKYDAS PREMIUM double leaf door is ready for the soundproofing test. Sound of different wave lengths is generated through dozens of speakers. The sound intensity on this side of the door is measured with a microphone. The intensity of the transmitted sound on the far side of the door is measured with a second microphone. The data from both microphones are read in to the computer software which calculates the soundproofing of the door.
