Description

For the audiological assessment of the speech-in-noise abilities of children with normal or impaired hearing, an appropriate test material is required. However, in Denmark there is none. The purpose of the current study was to develop a Danish speech material suitable for school-age children. Based on the 600 test sentences of the Danish DAT corpus (Nielsen, Dau & Neher, JASA 2014), 11 test lists comprising 20 sentences each were carefully constructed. The lists were evaluated in terms of their perceptual similarity and reliability with a group of 20 typically developing, normal-hearing children aged 6-12 yrs. Using stationary speech-shaped noise and diotic stimulus presentation, speech reception thresholds (SRTs) were measured twice per list and participant at two separate visits. The analyses showed that six test lists were perceptually equivalent. These lists are characterized by an overall SRT of -2.5 dB SNR, an average test-retest improvement of 0.4 dB, and a within-subject standard deviation of 1.1 dB SNR. The other test lists produced slightly higher SRTs, but were generally also usable. Altogether, it is therefore concluded that the developed test material is suited for assessing speech-in-noise reception in Danish school-age children.
