Description

For the audiological assessment of the speech-in-noise abilities of children with normal or impaired hearing, an appropriate test material is required. The purpose of the current study was to develop a Danish sentence material suitable for school-age children. Based on the 600 test sentences from the Danish DAT corpus (Nielsen, Dau & Neher, JASA 2014), 11 test lists comprising 20 sentences each were carefully constructed. These 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 recognition thresholds (SRTs) were measured twice per list and participant at two separate visits. The analyses showed an overall SRT of -2.0 dB SNR, an average test-retest improvement of 0.5 dB, and a within-subject standard deviation of 1.1 dB. Furthermore, eight test lists produced mean SRTs that were within 1 dB of each other. Altogether, it is concluded that the developed sentence material is suited for assessing speech-in-noise recognition of Danish school-age children.
