Subclaims¶

q2 i? With stationary noise, signal-to-noise ratios must be 5–7 dB higher for young children than adults to achieve comparable identification of speech or nonspeech signals, with adult-like performance reached at about 6 years of age. → Klatte M 2013 q2 i? With fluctuating maskers such as single-talker speech, adult-like performance is usually not reached before the age of 10 years. → Klatte M 2013

Evidence¶

Klatte M 2013¶

Klatte M, Bergström K and Lachmann T (2013) Does noise affect learning? A short review on noise effects on cognitive performance in children. Front. Psychol. 4:578. https://doi.org/10.3389/fpsyg.2013.00578

q2 · i? · review · r3

The review reports psychoacoustic studies showing children's speech identification in stationary noise requires "5–7 dB higher" SNRs than adults, with adult-like performance at about 6 years; with fluctuating maskers adult-like performance is usually not reached before age 10.

"With stationary noise makers, signal-to-noise ratios (SNRs) have to be 5–7 dB higher for young children when compared to adults in order to achieve comparable levels of identification of speech or nonspeech signals, with adult-like performance reached at about 6 years of age"

Learner Variables¶

• Age and Developmental Stage — predictor: learners who differ on it differ in outcomes
