Audio jammer and speech protection
Working principle:
The audio jammer uses ultrasonic mixing technology to emit ultrasonic signals that cannot be perceived by the human ear, but can be picked up by the microphone in cell phones and voice recorders. The ultrasonic have strong directionality and large sound pressure level, which can cover the normal speaking voice, making the audio picked up by the microphone just meaningless noise, thus avoiding verbal information leakage.
Application Scenario：
You can apply the audio jammer in any scenario where you need to protect the conversation, or you can choose the right audio jammer according to different application scenarios to achieve the best jamming effect. Its application scenes include:
- High-level confidential conference rooms: audio jammer can be installed on the conference table and under the table to form a full coverage of jamming signals to interfere with the possible existence of eavesdropping devices in the conference room.
- Centralized management of cell phones during meetings: Uniformly placing cell phones centrally outside the conference room makes it difficult for participants to accept the possibility of missing important calls. You can arrange audio jammer in the conference room, and then uniformly place cell phones in it, which not only protects the confidentiality of the meeting but also avoids the possibility of missing important calls, which is more acceptable to the participants.
- Prevent apps or viruses in the cell phone from eavesdropping on the conversation: there may be malicious apps or viruses in the smart phone, in order to prevent them from eavesdropping on the conversation, it is necessary to jam the microphone of the cell phone during the important conversation.
- To protect the temporary initiation of the conversation: some important conversations cannot be carried out in a confidential conference room, this time there is a need for a portable, but also more covert audio jammer to protect the temporary initiation of important conversations.
