Abstract: An amusement and entertainment system where participants try to continuously speak and/or sing while simultaneously listening to their own voices on a ½ second sound delay. The confusing feedback does not act as a sound enhancement echo but instead causes confusion, disorientation and amusement to the participants and others watching the participants. The system can be used by one or more participants and a third person can switch signals so that one or more participants or others watching can hear the resultant effects of another participant. The system can be table mounted so that participants can be seated about a table. Alternatively, the system can be mounted in a mobile vehicle. Video cameras and monitors can be used to further add to the amusement of participants and others watching the participants. Each headphone can include microphones built into the headbands.
