Testing time comparison between two procedures with new technologies of Automated Auditory Brainstem Response (AABR)

Area of Science:

• Audiology
• Neonatal screening
• Neuroscience

Background:

• Hearing impairment is a common congenital condition.
• Early detection of hearing loss in newborns is crucial for optimal development.
• Automated Auditory Brainstem Response (AABR) is a standard method for neonatal hearing screening.

Purpose of the Study:

• To compare the efficiency of two AABR protocols.
• To evaluate the impact of repetition rate and detection mode on AABR testing time.
• To identify optimal parameters for faster neonatal hearing screening.

Main Methods:

• A comparative study involving 30 newborns.
• Two AABR procedures were tested: Procedure 1 (53 Hz, one-sample test) and Procedure 2 (90 Hz, q-sample test).
• Auditory Brainstem Response (ABR) with click stimulus served as the gold standard.

Main Results:

• Procedure 2 (90 Hz, q-sample) was significantly faster, averaging 27.9 seconds.
• Procedure 1 (53 Hz, one-sample) averaged 84.8 seconds, approximately three times longer.
• Statistical analysis confirmed a significant difference in testing times between the two procedures.

Conclusions:

• The AABR protocol utilizing a 90 Hz repetition rate and the q-sample detection test offers a faster screening method.
• Optimized AABR parameters can improve the efficiency of neonatal hearing screening.
• Faster screening times may lead to quicker diagnosis and intervention for hearing loss.
