Abstract
A system that allows the teammates of an individual (such as a quarterback on a football team) to hear signals being called by that individual during the course of a sports competition, despite noise generated by an audience. The system includes a microphone positioned within the helmet of the signal caller connected to an audio amplification device, either positioned in the helmet or in some other part of the clothing or equipment worn by the signal caller. The amplified signal is then directed to one or more loudspeakers, again positioned either on the helmet of the signal caller or on the clothing or equipment worn by the signal caller. The loudspeakers are directed to the signal caller's teammates, positioned typically along a line of scrimmage. The system may be time-limited in operation in that the signal caller must specifically activate the system which thereafter remains activated only for a pre-set period of time before automatically shutting off. The components of the system may be connected to each other by wired or wireless signal lines.
