The microphone b is connected by flexible leads to a battery i and telephone receiver h, the latter being placed close to the ear of the person under treatment. The volume of sound passing to the microphone b is varied by a rotatable collar k having an opening which may be placed in or out of register with an opening j in the side of the tone-arm.
