ABR (Auditory Brainstem Response)
ABR is a neural response to an auditory stimulus by using scalp electrodes that pick up electrical potentials generated by the synchronous activity of neural populations in the brainstem.
It provides information about the inner ear and the central pathways for hearing. Hearing screening system provides auditory brainstem response screening to detect the presence or absence of potential hearing loss with speed and accuracy. The screening functions of this instrument are especially suitable for use with infants.

The Auditory Brainstem Response (ABR) is a diagnostic test that measures the electrical activity generated by the auditory nerve and the brainstem in response to sound stimuli. It is commonly used to assess the auditory system, diagnose hearing impairments, and evaluate the integrity of the auditory pathway. ABR has a range of applications in audiology and clinical settings.
Applications of ABR:
Newborn hearing screening: ABR is used as part of newborn hearing screening programs to identify infants with hearing loss. It is a non-invasive and objective test that can assess hearing sensitivity even in newborns who cannot provide behavioral responses.
Diagnosis of hearing impairments: ABR helps diagnose various types of hearing impairments, including auditory neuropathy spectrum disorder (ANSD), retrocochlear lesions, and auditory pathway abnormalities. It provides information about the integrity and function of the auditory nerve and brainstem.
Assessment of auditory function in difficult-to-test populations: ABR is particularly useful in evaluating auditory function in individuals who cannot provide reliable behavioral responses, such as young children, individuals with developmental disabilities, and individuals with severe cognitive impairments.
Intraoperative monitoring: ABR can be used during certain surgical procedures that may pose a risk to the auditory system, such as cochlear implant surgery or tumor removal near the auditory pathway. It helps monitor the integrity of the auditory system in real-time, reducing the risk of hearing damage during surgery.
Advantages of ABR:
Objective measurement: ABR provides an objective measure of auditory function without relying on subjective responses from the individual being tested. This is especially valuable in cases where behavioral responses cannot be reliably obtained, such as in newborns or individuals with communication difficulties.
Non-invasive procedure: ABR is a non-invasive test that does not require any surgical intervention. It involves placing electrodes on the scalp and earlobes to detect and record the electrical responses generated by the auditory system.
Early detection of hearing impairments: ABR can detect hearing impairments in newborns and infants at an early stage, allowing for timely intervention and appropriate management. Early identification of hearing loss is crucial for language development and overall communication skills.
Comprehensive assessment of auditory pathway: ABR assesses the entire auditory pathway from the cochlea to the brainstem. It provides information about the function and integrity of the auditory nerve, brainstem, and other auditory structures.
