“…Consistent with several studies (Chandrasekaran et al, 2009;Ziegler et al, 2009;Poelmans et al, 2011), dyslexics' performance was comparable to controls' when the stimuli were presented in quiet, but was significantly worse than that of age-matched controls in all noisy backgrounds. This deficit held true for the three consonant features examined here, which tempers previous finding of a specific impairment of reception of voicing and/or place of articulation in noise in dyslexic individuals (Hazan et al, 2013;Ziegler et al, 2009).…”

“…Interestingly, dyslexics' deficit was even observed when compared to younger, reading age-matched control children, suggesting that their speech perception deficit was not related to a mere delay in reading acquisition, but constituted a core difficulty inherent to dyslexia. Later studies replicated this finding using either vowel (Poelmans et al, 2011) or sentence (Chandrasekaran et al, 2009) identification tasks presented in a SSN background. However, Dole et al (2012) showed that dyslexic adults exhibited preserved perception of speech under SSN, but were impaired when presented with babble noise.…”

Studies evaluating speech perception in noise have reported inconsistent results regarding a potential deficit in dyslexic children. So far, most of them investigated energetic masking. The present study evaluated situations inducing mostly informational masking, which reflects cognitive interference induced by the masker. Dyslexic children were asked to identify a female target syllable presented in quiet, babble, unmodulated, and modulated speech-shaped noise. Whereas their performance was comparable to normal-reading children in quiet, it dropped significantly in all noisy conditions compared to age-, but not reading level-matched controls. Interestingly, noise affected similarly the reception of voicing, place, and manner of articulation in dyslexic and normal-reading children.

“…Independent work in Dutch has found similar results (Poelmans et al 2011), although a negative result was reported in Greek (Georgiou et al 2010). Brain imaging (EEG) studies suggest that the brains of children with dyslexia respond differently to slower rise times (90 ms but not 15 ms; see Stefanics et al 2011).…”

“…Poelmans et al, investigated sensitivity to frequency modulation, amplitude rise-time, speech in noise perception, and PA in children with dyslexia. They disclosed less sensitive to slow-rate dynamic auditory processing, speech in noise perception, PA, and literacy abilities in children with dyslexia than controls 23 . In other study of the same authors, carried-out in adults with dyslexia, researchers found deviant phonemic rate responses of the Auditory steady state responses 24 .…”

Objective Dyslexia is the difficulty of children in learning to read and write as results of neurological deficiencies. The objective was to test the Phonological awareness (PA) and Sinusoidal amplitude modulation (SAM) threshold in children with Phonological dyslexia (PD). Methods We performed a case-control, analytic, cross sectional study. We studied 14 children with PD and 14 control children from 7 to 11 years of age, by means of PA measurement and by SAM test. The mean age of dyslexic children was 8.39 years and in the control group was 8.15. Results Children with PD exhibited inadequate skills in PA, and SAM. We found significant correlations between PA and SAM at 4 Hertz frequency, and calculated regression equations that predicts between one-fourth and one-third of variance of measurements. Conclusion Alterations in PA and SAM found can help to explain basis of deficient language processing exhibited by children with PD.
