Abstract Employees and children in child day care centres are exposed daily to excessive noise levels which can be above 90 dBA over short periods. This study investigated the effectiveness of acoustic materials in reducing noise levels. Measurements were made of noise levels, reverberation time and acoustic radiation in 20 centres and noise dosimetry was carried out to evaluate worker exposure. Following an analysis of the results, various solutions for noise reduction were suggested. The addition of acoustic material on the ceiling and walls resulted in a reduction in noise levels of between 6 and 7 dBA.
