These ceilings work excellently for us. Our room has sloping ceilings up to 7m high, and a floor area spread over approximately 75sqm. There are large glass surfaces without curtains or drapes. The entire ceiling area is flush-mounted with the Ligno Trend elements. Most visitors simply find the ceiling beautiful and have no idea about its function – they don't miss anything acoustically either. There are simply no noticeable issues like reverberation, echo, tonal distortion, or the oppressive feeling of overly damped rooms. I work a lot with musicians. They immediately notice the absence of room acoustic peculiarities and ask about it. You can come by sometime.
