Protection
of acoustic data

• The WallNoise device consists of a control unit connected to magnetostrictive transducers (resonators).
• The vibration generated by the magnetostrictive transducer is transmitted to the wall through the transducer tip on the wall.
• The WallNoise device creates special acoustic samples, including the possibility of generating white noise, or street noise, which are transmitted by transducers to the wall, or the engineering wiring of the building, including window panels.
• WallNoise will completely nullify the original acoustic signal (room speech), with the original acoustic signal being uncorrectable.
• The unique system can perfectly secure the entire room against tapping from the outside.
• The WallNoise is controlled by a remote controller.

• Easy installation.
• Unique resonator mounting system.
• Use of magnetostriction means long service life, and safe operation in environments with high humidity.
• Possibility to connect up to 6 resonators to one control unit.
• Extremely high performance, yet compact.
• Suitable equally well for walls, floors, ceilings, window panels, or other structures, including engineering distribution of water, heat, gas, or air conditioning.
• Converts most of the generated signal into the desired form of acoustic-mechanical vibrations.
• Frequency characteristics optimally match the spectrum of human speech.
