One of the methods for objective evaluation of the hearing system is based on acoustic otoemissions. Particularly promising is the method based on measurement of the distortion product of otoacoustic emission as it is connected to the problem of tinnitus. Slow-varying magnetic field of low induction has been used in therapy of many diseases and ailments. It is expected that magnetostimulation will be effective in treatment of certain types of tinnitus by inducing the return of the organism to homeostasis. The aim of this study was to identify the changes in distortion product of otoacoustic emission levels in patients, prior and after the magnetostimulation. However any significant changes were found among patients with tinnitus, for the control group statistically important changes in distortion product of otoacoustic emission levels were observed.
