What devices can make sounds that block recording or eavesdropping devices?

I heard that there is a voice to prevent eavesdropping, is it true? Yes, through research, scientists have found that all recording equipment is suppressed by technology, so that the recording equipment cannot record normally; more precisely, it uses a device called "Anti recording jammer" to emit irregular white noise technology.

How White Noise Technology Works?

Generally speaking, white noise interference can be understood as when you turn on the radio or use a music player to play music while chatting with your friends, and the two of you talk about some more private topics under the cover of the sound of the radio or player. Wiretapping or recording equipment can only record noisy background sounds, and your voice is completely drowned out by background interference. The premise is that your voice should not be higher than the volume of background interference, and this natural interference sound is different from the white noise of professional recording jammers. This natural interference sound can be stripped by professional sound processing software in the later stage. Professional anti eavesdropping jammers cannot be stripped even with professional sound processing software.

There are two types of phone encryptors: those that block and jam radio waves, and those that make speech unintelligible. Both can be used to prevent eavesdropping.

A walkie-talkie-sized anti-tap jammer can protect the privacy of your apartment or room from eavesdroppers. However, this method of preventing interference has some caveats.

The 3G/4G mobile phone jammers that the general public can buy have very limited performance. The models that shield and prevent radio wave interference can reach up to 2.4Ghz, but cannot exceed 2.4Ghz.

In addition, the types of unpleasant sounds are not as the name suggests, as long as you make it unpleasant, you can completely eliminate your own voice. Also, in some locations, a license may be required for the use of interfering devices. If used by an unlicensed person, it may violate the Radio Management Act and heavy fines may be imposed.

If you also plan to install anti-tapping jammers in your home and office to prevent eavesdropping, you can browse jammermfg's radio jammer page, where there are different styles of professional anti recording jamming devices to provide you with privacy protection.
