HEARING AID SYSTEMS

摘要

This invention relates to a hearing aid system for the education of deaf children, and permits the incorporation of such children in a class of normal children. The child carries a conventional hearing aid provided with an integral inductive audio-frequency signal pick-up loop. The child also carries an audio-frequency signal inductive transmitting loop of such size that it can be worn in close proximity to the pick-up loop of the hearing aid. The teacher uses a microphone coupled by a suitable transmission system to the inductive transmitting loop. Thus the standard hearing aid enables the child to hear both ambient noise and a relatively distant teacher, with both signals at convenient sound levels.
