Abstract

315,333. Ohagen, H. April 5, 1928. Drawings to Specification. Eliminating needle-scratch by using damping- means during reproduction from loud-toned records.-A method of eliminating needle scratch in the reproduction of sound from gramophone records consists in (a), using records in which the amplitude of all the recorded sounds is such that, if reproduced on a gramophone in the ordinary way, the needle scratch would be masked by the sounds intended to be heard, but the latter would be too loud for satisfactory audition, and (b), during the reproduction, using a damping device which tones down the sounds intended to be heard, to a suitable amplitude, whilst it damps out entirely the extraneous sounds. Any suitable damper may be used, such as a plate fitted over the mouth of the horn, or a cone, lined with felt, inserted in the horn.
