Taking part in the activities is very important for the residents of a residential care facility. It keeps them active and it makes them feel good. However, the setting has to be optimal in order to accomplish these objectives. In Oostkamp, the multi-purpose hall of the care centre Sint-Jozef was not equipped optimally. Previous efforts of the director Frank Declerck, such as the nice cafeteria in a bistro atmosphere and the presence of a few cosy sitting areas required a finishing touch, namely optimum acoustics. Our expert recorded a truly terrible reverberation time, measuring up to 3 seconds. When every sound lingers in a room for such a long time, organising activities will be an impossible task.
