Abstract The present study aimed to provide preliminary information on the effi cacy of noise desensitization training in children with poor speech-in-noise scores. The participants were ten children, aged 8 to 11 years, who had poor speech perception in the presence of noise. Five children underwent training (experimental group) and fi ve children served as a control group who did not receive training. After 15-20 sessions of noise desensitization training for the experimental group, pre- and post-training performance for three speech comprehension tests was compared within and between the two participant groups. The non-parametric Mann-Whitney U test revealed that there was a signifi cant improvement in the scores of the experimental group following training. The experimental group had signifi cantly higher posttraining scores than the control group. These preliminary fi ndings warrant further research on the benefi ts of noise desensitization training for children who have diffi culty understanding speech in noisy conditions.

La présente étude avait pour but de fournir des renseignements préliminaires sur l’effi cacité de la pratique de désensibilisation au bruit chez les enfants ayant de faibles résultats de perception de la parole dans le bruit. Les participants étaient dix enfants, âgés de 8 à 11 ans, qui avaient une faible perception de la parole dans le bruit. Cinq enfants ont fait la formation (groupe expérimental) et cinq enfants ne l’ont pas fait (groupe témoin). Après 15 à 20 séances de désensibilisation au bruit pour le groupe expérimental, les résultats de trois tests de compréhension de la parole effectués avant et après la formation ont été comparés dans les deux groupes participants et entre les deux groupes. Le test non paramétrique U de Mann-Whitney a révélé qu’il y avait une amélioration importante des résultats dans le groupe expérimental après la formation. Le groupe expérimental avait des résultats plus élevés que le groupe témoin après leur formation. Ces conclusions préliminaires justifi ent la poursuite de la recherche sur les avantages d’une formation de désensibilisation au bruit chez les enfants qui ont de la diffi culté à comprendre la parole dans un environnement bruyant.
