-514 whether the sound is registered simultaneously or added afterward is of no importance, provided the synchronization is well done. Or there may be the exact and natural reproduction of sound and movement, when the perfection of the synchronization becomes of the first importance for the large majority of educational films. Another question interesting the users of educational sound films is the reproduction of the particular quality of the voice. Any sound, whether it be in the form of words or music or any other acoustic phenomenon has timbres which vary according to the size of the place where uttered or made and according to whether made in the open air or not. Various other factors, such as the way the walls of a room are draped or covered or the presence of people have their effect also. And since there is always a notable difference between the place where the sound was registered and where it is reproduced, a certain difference in the timbre of the voice will always be present, which is likely to undergo further alteration in the amplifier and the loud speaker. It is not therefore possible in the present state of cinematographic technique to register a sound film so as to be able to secure a mathematically exact reproduction of the timbre of the sounds. Though the matter is not of the first importance, care should certainly be taken to come as close as possible to exact reproduction. We may give as an example the filming of a bell foundry, where the resonance of the various metallic alloys has its instructional and scientific value. The matter is also of interest to radio technicians who are engaged in a special effort to solve the problem. (Translated from the German).
