Objectives: This study examined the use of auditory brainstem response (ABR) by classic clicks and verbal stimuli in young dyslexic adults to identify latency abnormalities.
Methods: Subjects included 10 dyslexic adults and 10 age-, sex-, IQ-, education-, and hearing sensitivity-matched normal subjects. Both groups had normal auditory status. Measurements included the absolute latencies of waves I through V; the interpeak latencies I-III, III-V, and I-V elicited by acoustic click; and the negative peak latencies of A and B waves, as well as the interpeak latencies of A-B elicited by the verbal stimulus "ma," created on a digital speech synthesizer.
Results: The measured latencies and interpeak latencies in response to both clicks and verbal stimuli were found delayed in eight dyslexic subjects, although they did not reach the level of significant difference. However, two dyslexic subjects had significantly delayed peak and interpeak latencies elicited by verbal stimuli.
Conclusions: There are dyslexic subjects who may have abnormalities in acoustic representation of a speech sound as low as the auditory brainstem, as elicited by the verbal stimulus "ma."

Investigating the effect of cochlear implant usage metrics on cortical auditory-evoked potential responses in adult recipients post-implantation.

Introduction: This study examines the effect of cochlear implant (CI) device usage metrics on post-operative outcomes in unilateral CI recipients. The primary objective is to investigate the relationship between CI usage frequency (average daily CI use) and duration (total years of CI use) on electrically evoked cortical auditory-evoked potential (eCAEP) response peak latency (ms) and amplitude (μV).
Methods: Adult CI users ( = 41) who previously exhibited absent acoustically evoked CAEP responses participated in the study.
Correlation between auditory brainstem responses, hyperacusis, and severity of autism spectrum disorder in young children with normal hearing at a tertiary referral center in Indonesia.

Introduction: Autism spectrum disorder (ASD) is a complex condition impacting social communication, behavior, and interests. ASD affects 1 in 100 children globally, with a higher prevalence in boys. Auditory disorders, including hyperacusis, are common in ASD, yet the correlation between Auditory Brainstem Response (ABR) wave latencies and ASD severity, especially with hyperacusis, is under-researched.

Article Synopsis
- The study compares the effectiveness of the Level-Specific CE-Chirp (LS CE-Chirp) stimulus versus the traditional click stimulus in auditory brainstem response (ABR) tests for diagnosing high-frequency hearing loss (HFHL).
- It involved 30 individuals with HFHL and 30 controls, measuring peak latencies and interpeak latencies of ABR waves after exposing them to both stimuli.
- Results showed that while the LS CE-Chirp had longer latencies at higher intensity in normal-hearing individuals, it did not show significant differences in the HFHL group compared to clicks, suggesting more consistent results with LS CE-Chirp but requiring further research for clinical effectiveness.

With technological advancement and economic competitiveness there is an exponential rise in the number of shift workers. Worldwide, healthcare workers constitute the single largest proportion of workers who work on shift duty in order to provide round-the-clock healthcare services to patients. Various studies have demonstrated an association between circadian cycle disturbance due to shift work and adverse health impacts.

Background: Animal audiology utilizes brainstem auditory evoked responses (BAER) as a non-invasive tool to assess hearing in animals, including Holstein dairy cows. Understanding cows' auditory capabilities is critical for their welfare, especially given their exposure to farm noise.
Objectives: This study provides preliminary normative BAER data for Holstein cows by focusing on absolute and interpeak wave latencies.
