A SURPRISING THING about sound is that when the human voice is electrically amplified, the amplification sometimes causes harsh overtones that make it difficult to understand. One of the jobs of Dictaphone research is to assure that any voice will be clear and intel ligible when a secretary "plays it back" for transcription. HOW TO REMODEL A WHISPER Dictaphone engineers don't aim to repro duce sound with absolute fidelity. You might call them sound sculptors.

The experience gained in the production of this war equipment will be available to extend the usefulness of the Dictaphone method after the war is won.
