NEW GRAMOPHONE NEEDLE.
ELIMINATING SCRATCH. It is not often, surely, that a psychologist turns inventor. In London, recently a specially-invited company of musicians and critics listened to a new gramophone invention by Mr. Ramsey, who has been for some time head of the Department of Experimental and Industrial Psychology in the University of South Africa. This invention was a needle, nonmetallic, which does away with what are known as extraneous frequencies. No metallic substance can, of course, be set in vibration without these cmbarrassfng phenomena/—the first cause of musical distortion—and the inventor of this new needle, who is already known as the inventor of the Burmese Colour Needle, certainly proved that he has added purity to tonal reproduction and abolished a good deal of surface noise and record scratch.
Tho new needle is fo bo called the Electrocolor. Occasional repointing, it is claimed, enables ono to outlast upward of 200 ordinary steel needles.
