Abstract

The method and the device can be used in radio engineeringfor sound reproduction. They improve the reception of the lowfrequencies under 700 Hz. The sound transmission is effected by atransmission device (10) in a transmission line (11) to a lowfrequency filter (20), respectively, an amplifier (25) and a soundreproduction device (27) fitted in the region of the breast of aman, and to a high frequency filter (30), an amplifier (35) and asound reproduction device (37) exercizing an effect on theperson's eardrum.11 claims, 2 figures
