“…It is interesting that different abilities of auditory comprehension seem to mature at a similar speed, which could be due to shared neural substrates. 12,26,27,39,40 Importantly, these results demonstrate that age-related adjustments in normal performance standards for clinical practices can be done across tests for each age range.…”

Objective: To improve the diagnostic efficiency of current tests for auditory processing disorders (APDs) by creating new test signals using digital filtering methods. Methods: We conducted a prospective study from August 1, 2014, to August 31, 2019, using 3 low speech redundancy tests with novel test signals that we created with specially designed digital filters: the binaural resynthesis test and the low pass and high pass filtered speech tests. We validated and optimized these new tests, then applied them to healthy individuals across different age groups to examine how age affected performance and to children with APD before and after acoustically controlled auditory training (ACAT) to assess clinical improvement after treatment. Results: We found a progressive increase in performance accuracy with less restrictive filters (P<.001) and with increasing age for all tests (P<.001). Our results suggest that binaural resynthesis and auditory closure mature at similar rates. We also demonstrate that the new tests can be used for the diagnosis of APD and for the monitoring of ACAT effects. Interestingly, we found that patients having the most severe deficits also benefited the most from ACAT (P<.001). Conclusion:We introduce a method that substantially improves current diagnostic tools for APD. In addition, we provide information on auditory processing maturation in normal development and validate that our method can detect APD-related deficits and ACAT-induced improvements in auditory processing.

“…W testach wykorzystywane są zarówno słowa sensowne, jak i nonsensowne. W jednym z ostatnich badań [34] sprawdzano wpływ rodzaju bodźców językowych na wykonanie testu filtracji mowy. Prezentowano 80 jednosylabowych słów sensownych i 80 nonsensownych, które nie różniły się pod względem parametrów filtracji.…”

Zdolność do rozpoznawania zniekształconych bodźców słownych jest ważnym aspektem przetwarzania informacji słuchowej. Testy sprawdzające tę umiejętność powinny wchodzić w skład baterii przesiewowych czułych na wykrywanie ośrodkowych zaburzeń przetwarzania słuchowego (ang. Auditory Processing Disorder, APD). W prezentowanej pracy przedstawiono podstawy teoretyczne oraz wybrane testy do oceny zdolności do rozpoznawania mowy zniekształconej w wyniku filtracji częstotliwościowej, kompresji czasowej lub mowy prezentowanej w obecności sygnału zakłócającego.

“…The slightly higher failure rate on DD than on LPFS testing (24.6% and 19%, respectively) in children with LD suggests these children experienced greater difficulties in the skills assessed by DD than those assessed by LPFS. The exact nature of these skills remains a topic of debate, with DD thought to assess dichotic listening as well as attention and short-term memory (Hugdahl, 2000;Lawfield, McFarland, & Cacace, 2011;Moncrieff, 2006;Musiek, 1983;Parkinson, 1974) and LPFS thought to assess monaural low redundancy and auditory closure while being influenced by the person's lexicon (Arnott, Goli, Bradley, Smith, & Wilson, 2014;Bellis, 2003;Bellis & Ferre, 1999;Weihing et al, 2015). While these greater failure rates show that children with LD experienced greater difficulties with these two auditory processing skills, caution is needed before suggesting this represents a greater prevalence rate of auditory processing disorder, as diagnosis of auditory processing disorder typically requires a more comprehensive assessment than the two tests of AP used in the present study.…”

Evaluating auditory function in primary school children with learning difficulties in Australia

Children who experience poor academic performance at school have been described as having learning difficulties (LD). These children are thought to show reduced performances in reading, written language and numeracy, and to be inactive and inefficient learners. Hearing is one of several factors thought to influence a child's learning at school with students spending at least 45% of their classroom activities that require listening and 45 to 75% of their time in the classroom comprehending their teachers' and classmates' speech. Hearing impairment can include loss of hearing sensitivity and/or impaired auditory processing (AP). While rates of peripheral hearing loss (PHL) in the Australian primary school-aged population is estimated to be between 3.4% and 12.8%, rates of impaired AP in this population are not available in Australia. Children with PHL and/or impaired AP often show behaviours similar to those reported in children with LD, suggesting that LD and hearing impairment could be related in primary school child populations. The present thesis aimed to investigate LD and hearing impairment in a schoolaged child population in the greater Brisbane region of Queensland, Australia. The thesis considered two main research questions: (1) Do children with LD have higher rates of impaired hearing and/or impaired AP compared with typically developing (TD) children?; and (2) What models might best explain any relationships between LD and hearing impairment? The first study chapter conducted a systematic review where the rate of PHL in the general primary school child population in Australia was considered. A search of five electronic databases yielded three studies that had quantitatively reported the PH results of screening and follow-up assessment of hearing in primary school children in Australia. The review concluded that the overall rate estimate of PHL in the primary school child population in Australia was between 3.4% and xii Financial Support
