Summary
Children as young as 16 months can participate in play-conditioned audiometry. This study shows that by age 3, most children can establish multiple hearing thresholds, aiding clinical assessments.
Area of Science:
- Pediatric Audiology
- Developmental Pediatrics
- Hearing Science
Background:
- Accurate hearing assessment in young children is crucial for early intervention.
- Traditional audiometry methods are challenging in pediatric populations.
- Play-conditioned audiometry (PCA) offers a behavioral approach for assessing hearing in children.
Purpose of the Study:
- To determine the minimum age at which children can participate in play-conditioned audiometry (PCA) in a clinical setting.
- To establish age-related benchmarks for successful threshold determination using PCA.
- To compare the efficacy of PCA with other pediatric audiometric techniques.
Main Methods:
- Conducted play-conditioned audiometry (PCA) on 294 children (182 boys, 112 girls) aged 16 months and older.
- Recorded age, gender, audiometric method, and number of successfully determined thresholds.
- Total of 449 examinations were analyzed, with some children tested multiple times.
- Results were compared with studies using visual reinforced audiometry (VRA) and condition-orientation reflex audiometry (COR).
Main Results:
- Over 35% of children aged 16 months and older could achieve at least one threshold via PCA.
- By age 2, approximately 50% of children could establish thresholds at three frequencies.
- By age 3, nearly 75% of children could establish six or more thresholds.
Conclusions:
- Play-conditioned audiometry (PCA) is feasible in clinical settings for children from 16 months of age.
- PCA provides valuable hearing threshold data in young children, complementing objective tests.
- VRA, COR, and PCA should be considered alongside objective measures like auditory brainstem response (ABR) and otoacoustic emissions (OAE) for comprehensive pediatric hearing evaluations.
