Abstract

A research was undertaken to investigate the loss of Italian language word intelligibility in classrooms caused by low signal to noise ratio and too high reverberation. In the first part of the work, impulse responses and background noises were measured in two primary schools using different mono, binaural and B-format probes. A dummy head with child morphology was also used for the first time in this context. It was thus possible to compare the performance of a child head to the conventional adult one. Then the restitution of the recorded sound fields in a dedicated listening room was accomplished, using stereo dipole and ambisonics technologies.
