Abstract:
The present invention relates to a communication disruption system. In a first audio path, a microphone receives input sound, an amplifier system amplifies the sound, and a sound system transmits a first output sound. In a second audio path, the microphone receives input sound, a delay circuit delays the sound, the amplifier system amplifies the sound, and the sound system transmits a second output sound. A target speaker will hear the first and second output sounds, with the first output sound being a reproduction of their speech heard nearly simultaneously with the original speech, and the second output sound being a reproduction of their speech heard slightly after the original speech. Due to the delayed auditory feedback effect, the target speaker's concentration will be disrupted, making it difficult for them to continue speaking.
