摘要

Improvements in the apparatus for hearing sound programs, characterized by the fact that the sound reproducing element and the receiving apparatus thereof, are linked through means of mutual relationship that are respectively coupled in the output stage of the sound player and the receiver's preamplifier input, which is powered by batteries and has a potentiometer and a switch, housed in a box mounted on a headphone helmet to be used by the hearing person, so that said means of relationship consent the distancing and displacement of that person with respect to the reproductive element within the scope of the room in which the latter is located, in order that the same person individually captures the hearing independently of other persons and without being interfered with by other auditions, voices or perceptible sounds in the cited field.
