Inspired by Shogakukan’s Neo series of picture books, the Zukan Museum Ginza in Tokyo describes itself as an ‘experience-based facility’ that fuses the digital and the real. Supporting the immersive and interactive journeys on offer are cutting edge video technologies more than 100 Genelec loudspeakers.
‘The museum faithfully recreates the ecosystem of the natural world, with different creatures appearing in each area, such as the forest, savanna and underwater, where the act of observing and recording the creatures is interactive,’ explains Jun Fujiwara of invisi Ltd – who handled the sound production and UX design. ‘For example, if you get too close to a creature, it will be startled and run away.’
‘The acoustical element is made up of three components: sounds produced by living creatures; background environmental sounds; and musical elements,’ adds Takashi Miyamoto of coton Inc – who was responsible for implementing the audio system and sound design. ‘The environment changes according to the time of day, just as it does in the real world. The musical elements are generated using coton’s music generation technology called soundtope, which automatically produces the most appropriate music based on the season and time of day, for a truly authentic experience.’
With 150 channels of sound in play, these acoustical elements create different worlds in each of the multiple areas within the museum. There is no physical separation between areas, so it was particularly important to ensure that transitions from one area to another are smooth and coherent.
‘In order to ensure seamless transitions between naturescapes, we used a common tonal scale between adjacent areas to prevent sounds from clashing with each other,’ Miyamoto says. ‘Furthermore, in terms of timbre, the placement of intermediate common tones between areas has the effect of a boundary partition, like a sound curtain. Another acoustical issue that emerged was the panning system, which pans the sound produced by the creatures. The loudspeaker arrangements didn’t allow us to use existing panners, so we had to develop our own system.’
According to Miyamoto, the precise localisation achieved by Genelec loudspeakers with the panning was the deciding factor in using them in the museum. ‘Other loudspeakers used different mechanisms to achieve localisation, but that was problematic in multichannel set-ups, and in general, they lacked the accurate sound reproduction we were looking for. Genelec’s superlative acoustic characteristics and flexible installation were a major attraction.’
‘As we wanted to prioritise the atmosphere of the museum, we tried to make the loudspeakers as invisible as possible,’ Fujiwara agrees. ‘We explored various options, including high positions on the ceiling and gaps in the structure. This meant the loudspeakers had to be as small as possible – and when it came to the size/performance ratio, Genelec was the obvious choice.’
At the Zukan Museum, 85 compact 8010 active studio loudspeakers, 23 of the slightly larger 8020 models and seven 7360 subwoofers were installed throughout the space. The 8010 is used widely throughout the museum due to its combination of performance and small footprint, while the 8020 is used specifically for reproducing creature sounds that require more low-end. In addition, Genelec’s range of accessories also proved invaluable to the project, with the 8000-420 short wallmount and 8000-416 truss mount both employed in the installation.
‘To create the world that living creatures inhabit, we received supervision from Emeritus university professors and other experts,’ says Takayuki Kitai of AID-DCC Inc – who was involved in the overall creative process of the facility. ‘We believe that we managed to provide an experience unique to this museum that cannot be obtained in conventional facilities. Since its opening, the museum has received favourable reviews from various fields as a new form of experiential facility. I hope many people will experience it.’
