From audio guide

to immersive visitor experience

Close-up of a person holding a tonwelt supraGuide ECO, a portable audio guide commonly used in museums and exhibitions. The device features a sleek black and red design with large tactile buttons, including a numeric keypad (1-9, 0 and a question mark), each marked in braille for easy accessibility. A central red button with play/pause function features prominently, along with a volume adjustment button above it. The display screen at the top shows text, including the product name ‘supraGuide ECO’ and a prompt: ‘Please press a number’. There is a cable connected to the device, leading to headphones, while a lanyard clip is visible at the bottom, enhancing portability. The background is a neutral beige wall, probably a museum or exhibition.

A visitor to the Reinhard Ernst Museum uses a supraGuide DIVA device from tonwelt, a digital audio-visual guidance system displayed on a smartphone-like screen. The user holds the device in one hand, wears a blue hooded sweatshirt and a black cap, and concentrates on an abstract artwork in the background. The artwork features soft, mixed tones of green, pink and purple. The device screen displays information about the artwork, with text, an audio play button and interactive options visible on the interface. The scenario highlights the integration of technology with art to enhance the museum experience. The user appears to be receiving information about the artwork in the background, as the supraGuide DIVA displays the same painting on its screen.

Two women participate in an interactive exhibition at the Pilsner Urquell experience, using tonwelt's supraGuide SPHERIC headphones for an immersive audio experience.

The exhibition features modern, illuminated circular panels on the wall, showing vibrant images related to the brewing processes, including a digital representation of fermentation or microscopic views of the ingredients. The brightly lit interactive stations have colourful touch points and other jars on display, creating a dynamic, high-tech environment that combines education with entertainment.

The guide uses a tour guide TG-48 from tonwelt, connected to a headset, while giving explanations to the group. In the foreground, two tour participants are seen: a woman in a denim jacket and another wearing a braid, hat and holding a TG-48 tour guide, both looking upwards, following the direction indicated by the guide. The setting shows a stone square with classical buildings in the background, highlighting a cultural and touristic atmosphere.

The audio guide has long since become a permanent feature in the toolbox of educational teams. There are clear reasons for this: The interpretation quality of the combination of hearing and seeing is particularly high. Visitors are given a curated key on how to discover your exhibition. The multilingual approach helps international guests to experience content in their own language.

Visitors with special needs can be integrated through low-barrier offers. So there are several reasons why you should use an audio guide in your exhibition. Our devices and solutions offer you even more: more flexibility, more options for technical integration, more accessibility, more interactivity, more satisfied visitors.

The natural lighting and artistic setting reinforce the idea of a professional curatorial or exhibition management meeting.

A smiling young woman in a white headset enjoys an immersive experience powered by artificial intelligence, surrounded by lights and circular shapes illuminated in shades of pink and purple.

Customised guided tours via audio guide or media guide are an important part of museum outreach and are now expected by many visitors as a common service. From audio-only guides with simple number entry or automatic triggering to fully integrated media guides with AV connection, interactions such as quizzes, collecting points for benefits, surveys, AR events and image recognition, there are a wide range of possibilities.

Decide for yourself how you want your exhibits to speak to your visitors and which visitor groups you want to address with your educational programmes. No matter which way you go, we have the perfect solution for your requirements and we're at your service.
