Efficient test of speech perception in noise for Mandarin-speaking pre-school children
What is it about?
It is widely recognized that standardized material should be used to assess speech perception abilities in clinical applications, but there is limited material in Mandarin Chinese and even fewer is available for young children. This study compiled 32 sentence lists from a corpus of 288 Mandarin sentences in babble, and evaluated whether the sentence lists were equivalent in difficulty by testing 64 adults and 54 children (aged 4 to 6 years) in different listening conditions. The study also examined the sensitivity of performance to different signal-to-noise ratios and determined the critical differences of the test for adults and young children separately.
Why is it important?
This study resulted in a new tool using Chinese sentence material for efficient assessment of speech perception in noise abilities in Mandarin-speaking children from 4 years of age. A recorded test of 27 lists that are equivalent in difficulty, with proven sensitivity and reliability, is available for young children; and 28 lists for adults.
