Abstract
Hearing is a complex ability that extends beyond the peripheral auditory system. A speech in noise/competition test is a valuable measure to include in the test battery when attempting to assess an individual’s “hearing”. The present study compared syllable vs. word scoring of the Greek Speech-in-Babble (SinB) test with 22 native Greek speaking children (6–12-year-olds) diagnosed with auditory processing disorder (APD) and 33 native Greek speaking typically developing children (6–12-year-olds). A three-factor analysis of variance revealed greater discriminative ability for syllable scoring than word scoring, with significant interactions between group and scoring. Two-way analysis of variance revealed SinB word-based measures (SNR50%) were larger (poorer performance) than syllable-based measures for both groups of children. Cohen’s d values were larger for syllable-based mean scores compared to word-based mean scores between groups for both ears. These findings indicate that the type of scoring affects the SinB’s resolution capacity and that syllable scoring might better differentiate typically developing children and children with APD.
Highlights
Hearing in everyday life requires skills that go beyond auditory sensitivity as measured by the pure tone audiogram [1]
SinB was administered as part of a diagnostic test battery for children seen for auditory processing disorder (APD) evaluation in the University Hospital of Thessaloniki Psychoacoustics Clinic
A three-factor (2 × 2 × 2) Analysis of variance (ANOVA) was used to test for statistical significance (Factors: group (APD vs typically developing), scoring type, ear)
Summary
Hearing in everyday life requires skills that go beyond auditory sensitivity as measured by the pure tone audiogram [1]. The term auditory processing disorder (APD) refers to a specific auditory deficit along the central auditory nervous system, including bottom-up and top-down neural connectivity [2]. Central auditory processing disorder is currently classified in the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10) as H93.25. Children with APD present with a wide range of auditory symptoms, most commonly difficulties understanding speech in background noise [3,4]. APD is associated with a range of functional deficits, including educational and psychosocial challenges [5,6]. APD is included in the World Health Organization’s (WHO) recent report on hearing [8]. While current audiological test batteries offer a relatively high degree of sensitivity and specificity in correctly diagnosing APD, approaches to improve efficiency, in non-English languages, are needed
