Abstract
THE technique of recording and reproducing sound for the purposes of “sound-picture films” has created a new problem, that of testing the quality of the reproduced sound. A very obvious method of testing the quality is of course just listening to the reproduction and comparing it with the original speech or music, if you remember it. But it is known very well that the human memory and our ears arc not very reliable. Asking different hearers in the audience, shows you almost as many opinions as there are hearers. I wish to remind you here of what A. O. Rankine, in a paper<sup>1</sup> on sound recording, said about the small effect of changing the density of sound records, on the clearness of reproduction. He thinks “only a rough approximation to the original vibrations is necessary in the reproduction of sound for ordinary audition.”
