A language-independent hearing screening self-test at school-entry.

Area of Science:

• Audiology
• Pediatric Health
• Global Health

Background:

• Hearing loss affects millions of children globally.
• Existing hearing screening methods lack cultural independence and accessibility.
• Early detection of hearing impairment is crucial for child development.

Purpose of the Study:

• To evaluate the validity and cultural independence of the Sound Ear Check, a tablet-based hearing screening tool.
• To assess the efficacy of three distinct testing procedures within the Sound Ear Check.
• To determine the potential of the Sound Ear Check as an international hearing screening solution for children.

Main Methods:

• Investigated the Sound Ear Check, a language-independent, tablet-based self-test using ecological sounds in background noise.
• Analyzed data from 692 children (aged 5 to 9 years, 4 months) across seven countries.
• Compared three test procedures: monaural adaptive, dichotic presentation in diotic noise, and fixed signal-to-noise ratio with a stopping rule.

Main Results:

• All three Sound Ear Check procedures demonstrated high sensitivity and specificity in detecting conductive, sensorineural, and mixed hearing loss exceeding 30 dB HL.
• Data collected from diverse countries showed consistency, with no clinically significant inter-country variations.
• The test proved effective across different cultural and linguistic backgrounds.

Conclusions:

• The Sound Ear Check is a valid and culturally independent hearing screening tool.
• It exhibits high accuracy in identifying significant hearing loss in young children.
• The Sound Ear Check presents a viable, scalable solution for international childhood hearing screening, addressing a critical global health need.
