Voice Amplified 1,000,000 Times
A loudspeaker so powerful that it can amplify the human voice 1,000,000 times and which may find application in the Fire Department field, has been developed by the Western Electric Company.
Measured at the horn’s mouth, sound is about 1,000 times louder than the roar at the foot of Niagara Falls. In spite of the tremendous amplification, the designers have obtained clarity. The giant voice, it is said, can reach firemen working inside buildings amid the crackle of flames. An officer on the outside of a burning building could direct the operation of the men within and facilitate rescue work.
