## Abstract The results published in the article __Gradient‐Induced Acoustic and Magnetic Field Fluctuations in a 4T Whole‐Body MR Imager__ by Wu et al. (Magn Reson Med 2000;44:532–536) appear to be consistent with the response of a time‐stationary linear system. Since a linear system is more simpl

High-"eld, high-speed magnetic resonance imaging (MRI) can generate high levels of sound within and around the scanner. The process that produces the gradient magnetic "eld is the primary cause of this noise. With the push to greater background magnetic "eld strength and gradient "eld switching spee
