|THE enormous power of loudspeakers now available is illustrated by the above photo of the famous scene when President Harding delivered his inaugural address. Investigation of audibility made it possible to plot the exact range of the amplifiers, as indicated in the picture.
It is remarkable that while the President's words were carried distinctly to listeners on the outskirts of the crowd, they were not made to sound too loud to people directly under the amplifiers. The reproduction of his voice by the loudspeaker was so perfect that those in the first row could not tell where the natural voice left off and where the amplified voice began. Walking away in a straight line from the platform, one could have detected no change in tone and but small variation in the volume.
Under a completely national system of government radio broadcasting such as that proposed by Mr. Howell in the accompanying article, it has been suggested that important public addresses and debates on vital practical problems, like the bonus, tariff, and prohibition, would be broadcasted over the whole country from Federal transmitting stations, and received not only by home radio users on their own sets, but also by huge crowds like the above, gathered around loudspeaking installations in the parks and other public meeting places of big cities.
