PURPOSE To analyze the presence of auditory cortical potential and its correlation with psychoacoustic detection of speech sounds as well as the latency of the P1, N1 e P2 components presented in free field in hearing impaired adults with and without amplification. METHODS We evaluated 22 adults with moderate to severe symmetrical bilateral sensorineural hearing loss, regular users of bilater...

Chronic otitis media in early childhood has often been related to subsequent difficulties in speech and language development. Our interest has been in the sequelae of the transitory hearing losses assmiated with otitis media wjth effusion (OME) on the development of auditory functions after the return of normal hearing senshivity in quiet. In parallel to this, we have also been interested in ch...
