In April 2009 Sofia Airport finished the construction of a noise protection screen at the aircraft engine testing platform. Constructing the screen and centralizing aircraft de-icing procedures at two platforms, Sofa Airport demonstrated its social commitment to the people living in the regions immediately affected by the airport operating activities.

The unique for the Balkans region equipment secures noise reduction through a solid acoustic barrier placed between the noise producer and the people exposed to its harmful impact. Its noise abatement effect during aircraft engines testing is about 17 dB(A), with 15 dB(A) prognosticated.
