IMAGINE a room so still that all you can hear is the beating of your own heart. A room as quiet as the depths of the sea - as silent as the stratosphere. It is double-walled and spring suspended. Inside, you have a feeling of absolute deadness. The soundless room we're talking about is in the Dictaphone Research Laboratory at Bridgeport, Conn. What a place to put history's prize renegade! Here he could meditate upon his crimes. With no sounds but those made by his own misbegotten self, each slightest move would be accusation, each whisper a shout of the vengeance to come. Frankly, we don't think a man with much on his conscience could stay sane for long in the Soundless Room. We may never have a chance to try it out on Der Fuehrer, but here at Dictaphone we're using the Soundless Room every day for his undoing. In this pool of profound quiet, some of the world's leading sound engineers are working to perfect new acous tical devices, some for war use, others for further development when peace comes. All the experience these sound scientists have gained through years of research on dictating equipment is now at Uncle Sam's disposal, to evolve better ways of recording and reproducing the human voice to meet the exacting requirements of the Army, Navy and vital war services. When peace comes, this same skill and experience will make these new conveni ences and services available to all business. Dictaphone Corporation, 420 Lexington Avenue, New York.
