Abstract:
An apparatus and method for presenting high-quality auditory stimuli, receiving patient communication and providing noise cancellation within the environment of magnetic resonance imaging (“MRI”) equipment. A microphone is positioned in a noise attenuated channel for recording of the patient's voice. A microphone is disposed outside of a noise attenuated channel to directly record the sounds of MRI equipment during its operation. The signals generated by the microphones are employed to reduce the output of noise generated by MRI equipment.
