(TU Delft Indoor Environment) Tenpierik, M.J. (TU Delft Building Physics) Bluyssen, P.M. (TU Delft Indoor Environment) Date 2019 Abstract The acoustic conditions of classrooms received a lot of attention in the last decades because of its important role in school children's comfort and performance. In a previous field study of 54 classrooms from 21 schools in the Netherlands, more than 85% of the 1145 primary school children reported that they were bothered by noise in the classroom. The objective of this study is to identify the effect of background sounds on children's performance, sound evaluation and influence assessment based on a lab study conducted in the SenseLab. 335 school children (9 to 13 years old)from the previous studied schools participated in the lab study. They were subjected to a series of listening tests and evaluations in two acoustic test chambers (acoustically treated or untreated)with one of seven randomly played background sounds: 45 dB(A)or 60 dB(A)traffic noise, 45 dB(A)or 60 dB(A)children talking, 45 dB(A)or 60 dB(A)music, or no sound (≈30 dB(A)). A two-way ANOVA was applied to analyse the interaction effect of sound type and sound pressure level (SPL)on children's performance, sound evaluation and influence assessment in each of the chambers. Statistically significant interactions between the impact of sound type and SPL on children's phonological processing performance and their influence assessments were found in the untreated chamber.
