Audiometry and tympanometry in children throughout one school year
Insights
Hearing and middle-ear abnormalities are common and fluctuating in children. Educational deficits correlate most strongly with overall decibel loss, suggesting regular audiogram screening is beneficial.
Area of Science:
- Pediatric Audiology
- Educational Psychology
Background:
- Hearing and middle-ear function are crucial for child development.
- Subtle auditory impairments can impact educational outcomes.
Purpose of the Study:
- To assess the prevalence and duration of hearing and middle-ear abnormalities in children.
- To identify correlations between auditory function and educational achievement.
- To develop efficient screening models for early detection.
Main Methods:
- 100 children underwent regular audiometry and tympanometry over a school year.
- Auditory test results were compared with educational assessments (intelligence, language, achievement).
- Four screening models were evaluated for efficiency and correlation with educational outcomes.
Main Results:
- 62% of children showed some abnormality, with a constantly changing affected group.
- Abnormal episodes averaged six weeks in duration; 39% had multiple episodes.
- Total decibel loss was the strongest predictor of educational deficit.
- An audiogram pass/fail screen per term showed the highest correlation with educational results.
Conclusions:
- Hearing and middle-ear abnormalities are prevalent and transient in school-aged children.
- Regular, simplified audiometric screening is effective for identifying children at risk for educational deficits.
- Efficient screening protocols can optimize resource allocation in audiological services.
Abstract:
One hundred children had audiometry and tympanometry testing every two to three weeks throughout 38 weeks of a school year. The results showed an average prevalence of some abnormality in 62% and that the abnormal group was constantly changing. Abnormal episodes had a median duration of three to four weeks and a mean of six weeks. Thirty-nine percent of the children had more than one episode. Comparisons were made between the different measures of hearing and middle-ear function and between these and educational tests of intelligence, language and school achievement. Educational deficit was related most closely to total decibel loss. Four screening models were designed to allow economical use of testers' time. Resultant test patterns were related to two to three week testing and to educational test results. The closest correlation with educational test results proved to be an audiogram pass/fail screen each school term.
