Acoustic design of Nordisk Film cinemas
The Nordic entertainment company Nordisk Film opened their first Swedish cinema on December 7th 2018 in Uppsala. This is the first cinema in Sweden that has a salon specially designed for and equipped with 4DX technology. The technology offers environmental effects such as seat vibrations, wind, rain and scents to enhance the movie experience.
A second cinema is now under construction in Malmö, and will open in 2020. Beyond the 4DX technology, the Nordisk Film cinemas offers high comfort and state-of-the-art technology in terms of video and audio. ÅF Sound & Vibration was commissioned by Atrium Ljungberg to carry out the acoustic design of the cinemas in both Uppsala and Malmö.
“With a comprehensive knowledge in the fields of building- and room acoustics, and expertise in cinema sound, this is a very exciting project, says Bengt Johansson, senior acoustic consultant. ”In a cinema salon, the focus is to create optimal acoustics that enables a comfortable experience.”
A good sound experience at the cinema is partly about the technical equipment, such as loudspeakers, but mainly about the acoustic conditions. ÅF Sound & Vibration was responsible for the building- and room acoustic. Building acoustics is about handling sound insulation and noise reduction, whereas the room acoustics aims at optimize audio distribution and reverberation in the salons.
In a cinema salon nothing should interfere with the movie experience. Traffic noise from outside the building or disturbing sounds from adjacent premises or adjacent salons must be avoided. Also, sounds from inside the salon should not disturb adjacent premises. “Sound insulation is of great importance and we have successfully developed a construction design that has been used in other cinemas” Bengt says.
Bengt explains that the cinema in Uppsala has a Dolby Atmos sound system installed in the ceiling and on the walls, allowing 60 separate channels. The acoustic solution is adapted to this loudspeaker system. “The Swedish audience can look forward to a comfortable experience with the introduction of innovative cinema technology” Bengt concludes.
