EduRa database: room models based on room acoustic measurements in primary and preschools

Abstract

This database provides five representative rooms in primary schools and preschools for acoustic simulations. A set of (binaural) room impulse responses (RIRs) simulated using an adult and a child artificial head are included for each room.Room acoustic measurements were carried out in Aachen’s primary schools and preschools, where 8 classrooms, 10 playrooms, 3 gyms, 3 multi-purpose rooms and 3 sports rooms were assessed. The dimensions and room acoustic parameters were then clustered to achieve five representative sceneries. Shoebox models with little furniture were created using the average dimension of each cluster, and room acoustic simulations yielding for the average reverberation time of each cluster were done to obtain the (binaural) RIRs.
