Resumen
Today, the evaluation of the acoustic quality of classrooms is mainly based on parameters such as late reverberation and noise level. However, when designing/optimizing classrooms the teaching situation must be considered, too. Especially the speech perception under the influence of deficient noise and reverberation in various classroom types are of high acoustic interest. In addition, the speech perception is heavily affected by different kinds and levels of noise inside the classroom. Thus, the whole binaural room acoustic situation has to be taken into account for a more realistic evaluation. Furthermore, recent investigations have shown that the differences between head-related transfer functions of children and adults are significant and cannot be neglected. In this contribution room acoustic simulations of classrooms are presented and discussed. In order to gain an impression of the room's influences on speech perception, the simulations are carried out with various setups using deficient noise and three different types of receivers (microphone, child, adult).
