In a quiet environment, even a small noise attracts the attention of the people around. In order to reduce the stress of speakers, listeners, and other people around them, we devised a tool to support conversation by converting voice into ultrasonic waves and outputting them from parametric speakers to deliver the sound to the conversation partner. Since light materials can be used for soundproofing ultrasonic waves, we used cardboard and newspaper as soundproofing materials. We confirmed that the sound converted by the tool can be used for conversation and soundproofed.
