Before to establish if the use of TACS cellular phones may be dangerous for man, it is useful to know the bioelectromagnetic interactions related to the SAR at frequencies and power used by TACS. In order to study the interaction mechanisms it is important to identify some biological response stimulated by electromagnetic exposition. A study on bioelectromagnetic effects induced by the use of TACS phones, evidencing a variation of the natural response of the auditory system was performed . This research was effectued applying a method based on the registration of the evoked acoustic emissions (transients and distortion products).The results of the experiments show that modulated electromagnetic fields modify the distortion products in about all the examined subjects.
