Research has shown that if two frequencies differing in 30Hz or less are presented in each ear, the brain will process these frequencies as an entirely separate third tone. This third frequency, or binaural beat, can stimulate production of brain waves if created in the correct frequency range. This study recruited 38 participants to determine if binaural beats in the beta range can increase at...

Cleft lip and/or palate (CL/P) disorders are commonly occurring congenital malformations and hearing impairment is a very common co-morbidity. Most previous research has only focused on middle ear disorders and related auditory consequences in this group. Studies of higher level auditory status and central auditory processing abilities of this group have been unsystematic. The present study was...
