Introduction: The Auditory Neuropathy/ Auditory Dys-synchrony (AN/AD) nowadays called the Auditory Neuropathy Spectrum Disorder (ANSD) is a hearing disorder characterized by a neural dyssychrony. Objective: To study the auditory and language in children with ANSD. Method: A descriptive and qualitative research was made, through the study of three clinical cases with diagnosis of ANS. Procedures included audiological testing, speech perception tests and evaluation of communication skills. Results: Clinical case 1 has deep hearing loss, detects the presence of the speech signal and differentiates words by suprasegmental features. This child responds assistematicaly to oral language, however, presents intentional multifunctional communication with broad participation in a dialogic activity through non-verbal symbolic means. Clinical case 2 has mild/moderate fluctuating hearing loss and is starting to identify words. He is able to differentiate words based on phonemic information, understands orders up to two actions related to immediate context and has intentional multifunctional communication with broad participation in dialogic activity through verbal means connected to the immediate context. On the other hand, clinical case 3 has deep hearing loss, does not detect speech, and does not understand the spoken language. Shows intentional multifunctional communication with broad participation in dialogic activity by symbolic and non-verbal means. Conclusion: All clinical cases of this study have classical audiological features of ANSD, preserved otoacoustic emissions, absence of auditory brain stem responses registration, with presence of cochlear microphonic. The hearing aid did not contribute to speech perception and oral language development in these children. However, they have communicative multifunctional intention based on gesture and signs. Therefore, these studied children are able to maintain a more effective communication when the interlocutor is familiar to this type of communicative strategy
