Abstract
A combination of active and passive techniques was used to reduce the sound levels in magnetic resonance imagers. These techinques were integrated into an existing audio sytem. Measurements of sound reduction varied with the protocol being used and averaged 9.9 dB with coaxial cabling and 14.2 dB with fiberoptic conduction of the feedback signal to a controller. Patient comfort and communication were improved.This publication has 2 references indexed in Scilit:
