**4. Final considerations**

Electrophysiological tests are important objective measures to verify the effectiveness of auditory training. In addition, it is important to emphasize that an electrophysiological evaluation plays an important role in predicting the gains to be expected from auditory training programs. Evaluation makes it possible to gauge whether the auditory training program should be continued, adjustments should be made, or a whole new intervention program begun. Thus, electrophysiological assessment is extremely important: it can indicate whether neural plasticity is possible (through improved synaptic efficiency and increased neural density) or measure the degree of functional plasticity (from behavioral changes brought about by training in auditory skills).
