What does a sound blocker do?
Jul 19,2024 XinShengHeng
A sound blocker is a device used to protect recording in a specific environment and can effectively interfere with digital and tape recorders, cameras, and microphones.
The white noise emitted by the damper is out of the frequency range of the human ear, so the recorder can only record a "buzz" and cannot record the content of the conversation of the speaker. After post-processing the sound, the recorded sound cannot be restored to the speaker's voice because the recording device captures only the noise. The device operates without any visible sound, effectively protecting conversations from being secretly recorded.
The features of the sound blocker include:
Digital recording: Interference can interfere with the sound of digital recording devices, digital recorders, recorded noise levels will be the longest distance from a specific distance, but even a distance that is mainly noise and recorded sound is difficult to hear the content of the speech.
Wireless or wired listening interference: Wireless or wired listening devices can be locked so that the sound collected through devices such as capacitive sensors is almost all noise and no speech can be heard.
Recording interference from wireless camera devices: It may interfere with the recording function of wireless camera devices, thereby converting sound collected through these devices into noise without affecting the image.
Microphone interference: Has the function of interfering with special superconducting microphones, which can effectively prevent the microphone from capturing sound at a specific distance.
In addition, the recording interceptor is also equipped with wireless detection remote control function, which can achieve remote control. This makes audio blockers an effective tool for protecting privacy and information security, especially in situations where confidential conversations or meetings need to be protected.
