Pure-tone and tympanometric screening: an ideal pair in identification audiometry
Journal of the American Audiology Society
|July 1, 1978
Summary
This study found that 42.8% of fourth graders had inconsistent hearing screening results between pure-tone audiometry and tympanometry. Integrating tympanometric screening is proposed for better identification of hearing issues in children.
Area of Science:
- Pediatric Audiology
- Hearing Conservation
- School Health Programs
Background:
- Hearing impairments in children can impact academic performance and development.
- Early identification of hearing issues is crucial for timely intervention.
- Current hearing screening methods may have limitations in detecting all types of hearing problems.
Purpose of the Study:
- To evaluate the consistency between pure-tone audiometry and tympanometry in a population of fourth graders.
- To determine the effectiveness of combined screening methods for identifying hearing concerns.
- To propose improvements for hearing screening protocols in schools.
Main Methods:
- A cohort of 140 fourth-grade students underwent both pure-tone audiometric and tympanometric screenings.
- Standardized pass/fail criteria were applied to both screening subtests.
- Results from both tests were compared to assess consistency.
Main Results:
- 52.2% of students passed both pure-tone and tympanometric screenings, while 5.0% failed both.
- A significant portion (36.4%) passed pure-tone but failed tympanometry, and 6.4% showed the reverse.
- Overall, 42.8% of the participants exhibited inconsistent results between the two screening methods.
Conclusions:
- There is a notable inconsistency between pure-tone and tympanometric screening results in school-aged children.
- Routine integration of tympanometric screening is recommended to enhance the detection of hearing losses and medically related ear conditions.
- This approach can improve the efficacy of hearing conservation programs in educational settings.
