Czech Radio Dvojka, Room Acoustics in the Studio Complex

As part of the modernization of the studio and the control room of Czech Radio Dvojka, we have ensured the complete installation of acoustic interior modifications according to the architectural design, including the documentation of production.

  • For the walls of both rooms, we have made perforated joinery and acoustic panels printed according to the wishes of the marketing ČRO department, we installed a grid ceiling with plasterboard elements to ensure the access to the cable distribution.
  • We designed a special acoustic window for the walls between the rooms to provide the necessary visual contact, but they do not let any sound through the three layers of glass of different thicknesses and the tilt of their vertical axis to reflect the sound towards the ceiling with absorbent material.
  • Before the installation, we performed acoustic measurements and based on them we adjusted the calculations and refined the original design.
