Eavesdropping Mike Listens In on Umpire’s Scraps at Ball Park (Dec, 1940)
Eavesdropping Mike Listens In on Umpire’s Scraps at Ball Park
So THAT baseball fans may eavesdrop on arguments between the umpire and players next spring, a “disappearing microphone” has been included in a new public-address system at a Wichita, Kans., stadium. Pressing a foot lever allows the microphone to pop from its underground box near the home plate. Through loudspeakers, the spectators then enjoy the novelty of hearing what is going on. In case a dispute becomes too heated for sensitive ears, the mike hastily retreats. As at left, it may also be used for announcements.
