| Abstract: | A group of 8 pupils born in 1962 and a group of 8 future teachers between 25 and 40 years of age, were submitted in 1975 to two types of tests in the presence of environment noises at various levels (45 to 75 dBa), in order to assess the influence of this nuisance on the pedagogic efficiency. The results show a nocivity threshold for the pupils at around 55 dBA and for the teachers at aroung 65 dBA. Furthermore, backward pupils suffer more in this context from the interference of noise than the advanced ones. |
