There are many studies in the literature that study the sensory profile of children with autism spectrum disorder (ASD), which can essentially have three types of behavior: (1) Registration, (2) Seeking, (3) Sensitivity, and (4) Avoiding. However, there are few studies dedicated to the study of the sensory profile of children with autism. A child's sensory profile is closely related to the way they deal with the world and their social interaction. The existence of tools that allow the study of the behavioral response to the sounds of children with autism spectrum disorder, will allow the application of targeted therapies in the future. Therapies targeted and adjusted to each profile observed in these children will allow to attenuate these maladjusted behavioral responses, or even overcome these deficits, if there is an early and precise intervention.

Inclusion Criteria:
* Case group: children diagnosed with ASD according to the DSM-V criteria (Diagnostic and Statistical Manual of Mental Disorders 5th edition) and performed by a Pediatrician, Pedopsychiatry or Pediatric Neurologist; age between 3 and 6 years at the time of the audiological assessment; children with indication for BAEP; children who reveal thresholds within the normal range in the BAEP.
* Control group: children with typical development for their age; children with indication for BAEP due to the presence of risk factors for deafness (included in the universal neonatal auditory screening program) or due to delay in language development alone requiring clarification; age between 3 and 6 years at the time of audiological examinations; children who reveal thresholds within the normal range in the BAEP.
Exclusion Criteria:
* Case group: late diagnosis of ASD (\> 6 years); associated pathology, such as: neurological (epilepsy, neurodegenerative disease, severe hypoxic-ischemic encephalopathy), congenital infections (TORCH group infections) with hearing impairment, chromosomal abnormalities (Down syndrome, fragile X syndrome), neurocutaneous syndromes, endocrine disorders and metabolic disorders (phenylketonuria), cleft palate or facial malformations; active ear pathology at the time of audiological evaluation (otitis media, external auditory canal infection or malformation); increase in auditory thresholds in BAEP.
* Control group: associated pathology, such as: neurological (epilepsy, neurodegenerative disease, severe hypoxic-ischemic encephalopathy), congenital infections (TORCH group infections) with hearing loss, chromosomal abnormalities (Down syndrome, fragile X syndrome), neurocutaneous syndromes , endocrine and metabolic disorders (phenylketonuria), cleft palate or facial malformations; active ear pathology at the time of audiological evaluation (otitis media, external auditory canal infection or malformation); increase in auditory thresholds in BAEP.
Primary outcome measure(s)
Findings in Brainstem Auditory Evoked Potentials (BAEP) — 3 years Brainstem Auditory Evoked Potentials will be performed under propofol sedation. Absolute latencies (ALs) of waves I, III, and V and interpeak latencies (IPLs) I-III, III-V, and I-V were measured, as well as the amplitudes of waves I and V. These values will be compared between the group of cases (children with ASD) and controls (children without ASD). It will be evaluated whether any of these values will be persistently outside the values considered normal in children with ASD.
