We believe this is the easiest way to infiltrate a meeting and steal secrets. Anyone who has a phone can be wiretapped and everyone has a phone. The purpose of Shield is to minimize the risk for wiretapping. The full report will be sent upon request. The tests confirm that Shield effectively stops devices from eavesdropping. ![]() Shield has been subject to testing in an independent acoustic laboratory. The sound masking can be played at two different volumes allowing the security team to customise it to the environment. To ensure the sound cannot be reverse engineered and removed from the recording, Shield plays a three-layered randomised sound algorithm that consists of a random (pink) noise and several synthetic voices.Ĭustomisable. Through detailed testing, a bass reflex channel has been calibrated to ensure the sound box produces a sound at the lower Hertz level that matches and therefore masks human speech. The speakers are positioned to create maximum effect. The sound box consists of two small speakers and a bass reflex channel. Shield has a noise box that is built into its interior cabin. It is of vital importance that sensitive information never reaches the microphones.
