Architects will design venues with peerless acoustics. Builders will construct homes with perfect soundproofing. Events will adapt convention centres for music, theatre, and dance. Conductors will customise opera halls for their music. Orchestras will rehearse in replicas of real concert halls.<\/span><\/p>\n<p><span>But before those fantasies became reality, the digital twin was called for an audition. Salzburg provided two formidable tests: a fabled festival venue and the music of Mozart.<\/span><\/p>\n<h2>Digitising sound<\/h2>\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1409374 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/08\/hires-grosses_festspielhaus_2_c_sf_luigi_caputo-1.jpg\" alt=\"Photo of Salzburg's Festival Hall, which now has a digital twin that simulates Mozart's musi\" width=\"1640\" height=\"1158\"><figcaption>The Large Festival Hall was built specifically for the Salzburg Festival.

As the name suggests, the venue is also immense. The 100-metre stage is among the widest in the world. Around 2,200 people can attend each performance.<\/span><\/p>\n<p><span>Their seats offer different music experiences. They also <\/span><i><span>affect<\/span><\/i><span> the music. Their materials, locations, and the people sitting on them all influence the acoustics that resound throughout the hall. So do the carpets on the floor, the musicians on the stage, and the instruments they play.&nbsp;<\/span><\/p>\n<p><span>The architecture also dramatically impacts the sound. When the building pushes echoes and reverberations into cacophonous directions, acoustic panels are installed on walls and ceilings to soothe the strains.<\/span><\/p>\n<p><span>The digital twin had to model each of these effects. Siemens assigned the task to <a href=\"https:\/\/plm.sw.siemens.com\/en-US\/simcenter\/\" target=\"_blank\" rel=\"nofollow noopener\">Simcenter<\/a>, a software portfolio for developing and testing simulations.<\/span><\/p>\n<p><span>The software first analysed data on the shape, structure, and contents of the hall. All the underlying materials were then precisely defined. Each can cause sound waves to behave differently.&nbsp;<\/span><\/p>\n<p><span>Soft curtains absorb the waves, while metal furnishings reflect them. When they <\/span><span>bounce off concrete walls, they generate a distinct acoustic reaction. If they hit a seat, they will create another reaction.<\/span><\/p>\n<p><span>Siemens analysed these effects through two core techniques: <\/span><a href=\"https:\/\/www.mathworks.com\/help\/audio\/ug\/room-impulse-response-simulation-with-stochastic-ray-tracing.html\" target=\"_blank\" rel=\"nofollow noopener\"><span>impulse response measurements and ray tracing<\/span><\/a><span>. Together, they measured and simulated the flow of sound through the hall.<\/span><\/p>\n<h2>A virtual stage for Mozart<\/h2>\n<p><span>Engineers first installed <\/span><span>12 microphones around the auditorium. On the stage, they placed 11 high-quality speakers in the positions of the instruments.&nbsp;<\/span><\/p>\n<p><span>Each speaker then sent small signals around the room. For a set number of seconds, they transmitted a broad frequency band at a certain duration and precise volume.<\/span><\/p>\n<p><span>As the signals circled the hall, microphones recorded their effects. The results were then sent for analysis.<\/span><\/p>\n<p><span>\u201cWith that technology, we get the individual signature sound of the room,\u201d <\/span><span>Arnold Holler, an engagement manager at Siemens Simcenter, tells TNW.<\/span><\/p>\n<p><span>Siemens then embedded that signature into the digital hall.&nbsp;<\/span><\/p>\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1409375 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/08\/Picture1.png\" alt=\"Software showing the digital twin of Salzburg's Festival Hall, which now simulates Mozart's musi\" width=\"1640\" height=\"854\"><figcaption>The digital twin of Salzburg\u2019s Festival Hall.

Computer models then examined the acoustic behaviour.<\/span><\/p>\n<p><span>\u201cWe correlate the simulation with the measurements and map the model to reality,\u201d Holler says. \u201cWith that, you get the digital twin. Otherwise, you just have a digital model.\u201d.<\/span><\/p>\n<p><span>Assured that their replicant was fully developed, the team released the virtual doppelganger.&nbsp;<\/span><\/p>\n<p><span>The finished twin replicates endless musical configurations. Users can then explore the impact <\/span><span>on every seat in the hall.<\/span><\/p>\n<p><span>From remote locations, they can experiment with sounds, <\/span><span>materials, and layouts. All their tweaks could transform the acoustics. By simulating them in a digital twin, they will create evidence for decisions in the real world.<\/span><\/p>\n<p><span>More acoustic digital twins are already in the works. But technology still has to convince sceptics. To dispel their doubts, Siemens has turned to <\/span><span>Salzburg\u2019s favourite son.&nbsp;<\/span><\/p>\n<h2>Mozart enters the digital stage<\/h2>\n<p><span>Siemens built the digital twin into an XR application. Named the \u201cSound of Science,\u201d the <a href=\"https:\/\/thenextweb.com\/topic\/apps\" target=\"_blank\" rel=\"noopener\">app<\/a> transports us into a 3D model of Salzburg\u2019s Large Festival Hall. We then explore the music playing in the venue, adjusting sounds and structures as we listen.&nbsp;<\/span><\/p>\n<p><span>We move instruments, expand orchestras, add acoustic panels, and listen to the effects from different seats in the venue. Every change has an audible impact on the acoustics.<\/span><\/p>\n<p><span>Stephan Frucht, the artistic director of the Siemens arts programme, chose <\/span><a href=\"https:\/\/www.youtube.com\/watch?v=X3j5f9ggN-4\" target=\"_blank\" rel=\"nofollow noopener\"><span>Mozart\u2019s 29th Symphony<\/span><\/a><span> for the experience. Blending transparent textures with sophisticated techniques, the music showcases the digital twin\u2019s capabilities.<\/span><\/p>\n<p><span>An esteemed composer in his own right, Frucht cut the track in a Berlin studio. One instrument after another was recorded onto individual files. All were integrated with the digital twin. The audio signals were then fed into the XR software.<\/span><\/p>\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1409382 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/08\/Screenshot_20240808_191111_VLC.jpg\" alt=\"The XR app for the digital twin that plays Mozart's music\" width=\"1074\" height=\"608\"><figcaption>The app provides views \u2014 and listens \u2014 from the conductor\u2019s perch, the stalls, and the upper circle.

It also shines a new light on Siemens.<\/span><\/p>\n<h2>Music\u2019s digital future<\/h2>\n<p><span>Founded back in 1847, Siemens has a lengthy history of engineering excellence. The Munich-based firm is also Europe\u2019s largest industrial manufacturer. But the current company has another focus: <a href=\"https:\/\/thenextweb.com\/topic\/software\" target=\"_blank\" rel=\"noopener\">software<\/a>.&nbsp;<\/span><\/p>\n<p><span>Digital twins are a central component of today\u2019s business. They\u2019re used to monitor and improve various industrial operations, from manufacturing plants to energy grids.&nbsp;<\/span><\/p>\n<p><span>The Salzburg system shows the twins can also optimise acoustic conditions. Frucht has even loftier ambitions for the project. He believes the music can influence industrial applications.<\/span><\/p>\n<p><span>\u201cAfter all, innovation can also come from culture,\u201d he says.<\/span><\/p>\n<p><span>He points to a precedent set by Salzburg\u2019s second favourite musical son: Herbert von Karajan. A celebrated (<\/span><a href=\"https:\/\/www.classical-music.com\/articles\/trouble-karajan\" target=\"_blank\" rel=\"nofollow noopener\"><span>and controversial<\/span><\/a><span>) Austrian conductor, Karajan inaugurated the Large Festival Hall. He was also involved in developing the compact disc. One of his recordings was the first work ever pressed onto the plastic.<\/span><\/p>\n<p><span>Legend has it that he also set the CD\u2019s parameters. He reputedly demanded that a single disc must have space for Beethoven\u2019s 9th Symphony. The outcome was a 74-minute capacity.<\/span><\/p>\n<p><span>If music has a similar impact on digital twins, Mozart could have a whole new breed of descendants.<\/span><b><\/b><\/p>\n<p> <a href=\"https:\/\/thenextweb.com\/news\/mozart-and-siemens-acoustic-digital-twin\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Although Mozart has no living descendants, his music still has countless inheritors.
