Aalto University Researchers Measure Applause and CO2 Levels in Kapsäkki’s UKK Musical

The UKK musical, produced by Music Theatre Kapsäkki and Greta Production, is a vibrant cabaret about Finland’s political history during the era of President Kekkonen. Its impact is now being studied scientifically. The research, conducted in collaboration with Aalto University’s MAGICS infrastructure, Greta Production, and Kapsäkki, measures audience and performer experiences through innovative methods, including various sensors and surveys.

‘We are testing two new measurement techniques. Using microphones in the ceiling, we capture sounds from both the audience and the stage, allowing us to understand how and when the audience reacts, such as through applause, laughter, or comments. With CO2 measurements, we expect to detect moments when the atmosphere in the room is particularly heightened,’ says Antti Ruotoistenmäki, academic coordinator of the Magics infrastructure.

The CO2 levels in the auditorium reveal how the audience breathes during the performance. For instance, accelerated breathing can indicate heightened tension. According to the researchers, it will be interesting to observe whether the experiences of the performers and the audience are similar across different shows.

Data on experiences and emotional reactions are collected using more traditional methods as well. Touchscreens are available for audience members to immediately rate their experience, and they are also asked to complete a detailed questionnaire at home about their reactions. Additionally, the performers fill out a short survey after each show.

By combining innovative research and technology, the researchers hope to gather information that will benefit artists. Such measurement methods have rarely been applied in the field of performing arts.
