ABSTRACT:
A MRI sound system transducer and headset provides music and operator communication for the Magnetic Resonance Imaging (MRI) patient. The inventive system includes a pneumatic, non-magnetic transducer which converts electrical output from a music source or operator microphone to moving air, and delivers this pneumatic audio signal through plastic tubes inside the high magnetic field area to a headset which attenuates the ambient noise in the area.
