The problem
Not only new constructions or modern glass buildings can suffer from poor acoustics. Ordinary homes with flat plaster and many hard materials in the furnishings can also suffer. This was also the case at Dr. Jan Fransis' general practice. When the fall of 2017 arrived, he decided to have us improve the acoustics in his practice. After all, both in his practice room and in the waiting room, he was experiencing a very unpleasant chilly sound and reverberation.
