Abstract: An anti-eavesdropping device is provided which consists of a first structure for containing sound waves produced by a first person. This first structure includes a sound attenuating breathing device. This first structure includes a first mechanism for converting sound waves into electric waves, which are then transferred to a second structure which is for forming an acoustic seal about the ears of a second person. This second structure includes a second mechanism for converting the electric waves back to the sound waves. Because the device enables two or more people to engage in conversation, in such a way that no sound can escape into the environment to be detected in any way, by the human ear or by any kind of eavesdropping device utilizing direct or indirect interception of sound waves (such as microphones or vibration--detection equipment utilizing laser beams), the device can be used to produce confidential communications in the presence of eavesdroppers and eavesdropping equipment.
