New system for neonatal hearing screening based on auditory steady state responses

Area of Science:

• Audiology
• Neuroscience
• Biomedical Engineering

Background:

• Hearing loss diagnosis traditionally relies on subjective patient responses.
• Objective measures are crucial for accurate and efficient hearing assessment, especially in difficult-to-test populations.

Purpose of the Study:

• To introduce NEURONIC-A 6.0, an automated system for objective hearing loss detection.
• To detail the system's methodology for recording and analyzing auditory steady-state responses (ASSRs).

Main Methods:

• The system generates digitally Amplitude Modulated tones across various frequencies and intensities.
• Simultaneous stimulus presentation via earphones and bone vibrators is supported.
• Automated artifact rejection and frequency-domain quantitative analysis are employed for response detection.

Main Results:

• The system automates the entire recording and analysis process.
• Objective, binary (pass/fail) results are generated without examiner intervention.
• Quantitative indicators ensure reliable control over response acquisition.

Conclusions:

• NEURONIC-A 6.0 provides an automated and objective method for hearing loss screening.
• The system enhances efficiency and accuracy in auditory response assessment.
• This technology facilitates rapid identification of potential hearing impairments.
