ABSTRACT:
Introduction: Several subjects exposed to neurotoxins in the workplace need to be assessed for central auditory deficit. Although central auditory processing tests are widely used in other countries, they have not been standardized for the Polish population. The aim of the study has been to evaluate the range of reference values for 3 temporal processing tests: the duration pattern test (DPT), the frequency pattern test (FPT) and the gaps in noise test (GIN). Material and Methods: The study included 76 normal hearing individuals (38 women, 38 men) at the age of 18 to 54 years old (mean ± standard deviation: 39.4±9.1). All study participants had no history of any chronic disease and underwent a standard ENT examination. Results: The reference range for the DPT was established at 55.3% or more of correct answers, while for the FPT it stood at 56.7% or more of correct answers. The mean threshold for both ears in the GIN test was defined as 6 ms. In this study there were no significant associations between the DPT, FPT and GIN results and age or gender. Symmetry between the ears in the case of the DPT, FPT and GIN was found. Conclusions: Reference ranges obtained in this study for the DPT and FPT in the Polish population are lower than reference ranges previously published for other nations while the GIN test results correspond to those published in the related literature. Further investigations are needed to explain the discrepancies between normative values in Poland and other countries and adapt tests for occupational medicine purposes. Med Pr 2015;66(2):145–152
