The Lahti Symphony Orchestra’s home concert hall is located at the Sibelius Hall in Lahti, a wooden congress and concert centre completed in March 2000. The orchestra’s new home concert hall has outstanding acoustics that are considered one of the best internationally. Sibelius Hall has provided the Lahti Symphony Orchestra more opportunities to expand its authentic sound. Main Hall like a grand Instrument
The Main Hall is an acoustic miracle. Its unique surroundings create unforgettable musical memories for the concert visitors. The auditorium, the stage and the balconies from an oval structure inside the so-called shoebox hall. Adjustable acoustics is achieved by a moving canopy above the stage, the reverberance chambers along the sidewalls with 188 acoustics doors and the woolen acoustic banners. The auditorium’s corrugated walls scatter reflecting sounds. Space has been reserved for a concert organ behind the stage balcony. The sophisticated colouring of the Main Hall is a combination of graphite grey, natural white and the warm red of old string instruments. The floor is made of oil- and heat-treated smoke birch parquet. A glass facade covers the massive wall elements, the sandwich-structured laminated veneer lumber panels, filled with sand (18 cm thick insulation) and mineral wool. The vast open space between the glass wall and the elements improves the hall’s sound insulation. All main Hall’s load-bearing structures are made of glued laminated timber.
