Summary
This study establishes reference values for temporal processing tests in Poland. The duration pattern test (DPT) and frequency pattern test (FPT) showed lower norms, while the gaps in noise test (GIN) aligned with international data.
Area of Science:
- Audiology
- Neuroscience
- Occupational Health
Background:
- Workplace neurotoxin exposure necessitates central auditory deficit assessment.
- Standardized central auditory processing tests are lacking for the Polish population.
- Temporal processing deficits can impact individuals exposed to occupational hazards.
Purpose of the Study:
- To evaluate reference values for three temporal processing tests: duration pattern test (DPT), frequency pattern test (FPT), and gaps in noise test (GIN).
- To establish normative data for the Polish population, aiding in occupational health assessments.
- To investigate potential associations between test results and demographic factors like age and gender.
Main Methods:
- Study included 76 healthy adults (18-54 years) with normal hearing.
- Standard ENT examinations were performed on all participants.
- Three auditory processing tests (DPT, FPT, GIN) were administered.
Main Results:
- Reference ranges: DPT ≥ 55.3% correct, FPT ≥ 56.7% correct.
- GIN test mean threshold: 6 ms.
- No significant associations found between DPT, FPT, GIN results and age or gender; symmetry between ears was observed.
Conclusions:
- Polish reference ranges for DPT and FPT are lower than international norms; GIN results align with existing literature.
- Discrepancies in normative values require further investigation.
- Adaptation of these tests for occupational medicine in Poland is recommended.
