Product Details
Sound insulation treatment at pipeline cable interface
Product Introduction
A compact sound masking jammer that generates specific vibration frequency sound waves when turned on, providing vibration interference to pipes passing through indoor enclosure structures, achieving the purpose of sound vibration interference protection.
It can be powered independently by a battery or centrally by a dedicated power supply. It can be switched on and off using a remote control and deployed at the location of the pipeline passing through the enclosure structure of the confidential conference room.
The system complies with the national confidentiality standards: BMB26-2012 "Confidentiality Requirements and Testing Requirements for Confidential Meeting Rooms" related technical requirements.
PRODUCT FUNCTION
According to the different mechanisms of sound leakage, it can be divided into air sound leakage and vibration sound leakage. For air sound leakage, the thief can directly listen to it with human ears at the boundary or use directional microphones and other instruments to eavesdrop. For vibration sound leakage, the thief can use pipelines as carriers to pick up sound signals based on the principle of sound vibration leakage, and use vibration eavesdroppers to eavesdrop. The main characteristic of this type of sound leakage is that sound waves first act on solids in the room, and then propagate to the far end through solid sound transmission.
To prevent possible remote eavesdropping of vibration sounds, a pipeline sound interference system is installed on a metal pipeline, and voice interference vibration signals are applied to the metal pipeline to attach the interference signals to the possible vibration sound waves returned by the vibration eavesdropper, annihilating the normal voice signals and preventing the vibration sound wave eavesdropper from receiving and restoring the normal voice signals, in order to achieve the purpose of protecting the voice signals.
