Abstract

In a method for local reduction of the operating noise produced by a medical diagnostic or therapy device, antisound is produced locally by a sound source. The sound source used is a highly directional parametric loudspeaker. As a result, disturbing operating noises can be limited locally and suppressed effectively.
