Because it was not possible to experiment with changes to the acoustic environment of the Hemicycle of the Spanish Congress while it was in session, a simulation model was created. Different methods were tested to improve the intelligibility after the simulated model was validated with measurements of the unoccupied space. From this work it was concluded that an overall redesign of the sound reinforcement system was required. Even though there were some 350 small loudspeakers for the deputies, they were often not at their seats. As a result, loudspeakers contributed to the background noise without enhancing intelligibility.
