Standardization in Room Acoustics Room acoustics and electroacoustic systems are critical components of building design that can impact the quality of sound and speech intelligibility in various environments, from concert halls to classrooms and offices. In Hungary, the journey towards standardization in this area began over a century ago, but it wasn’t until 2020 that […]

Background noise in classrooms: How it affects performance (EIAS 2023)
EIAS 2023: Chiara Visentin, senior researcher at Eurah Research in Italy, held an interesting presentation at the recent EIAS2023. It was about the topic of background noise in classrooms, and how this affects the pupils’ task performance. Even though a classroom meets the minimum acoustic requirements, there is no guarantee that the room is an […]
The Influence of Acoustics on People featuring Neurodisorders
Dr Marco Caniato – Free University of Bozen in Italy presented this paper at EIAS2023. The influence of acoustics on people featuring neurodisorders. State-of-the-art and new perspectives As recently by the World Health Organisation, the percentage of people in the world suffering from neurodisorders, neurocognitive or neurodevelopmental disorder (as referred and described in the Diagnostic […]
Acoustics and Air Quality – The Impact on Student Concentration and Fatigue
At EIAS 2023, findings from the former ISF (institute for interdisciplinary school research) and Gerhart Tiesler were presented by Rainer Machner. The research was initiated in 2005 by public discussion of air quality in offices and schools. One pattern for the research we found in “Handbuch der Schulhygiene” (handbook of hygiene in schools), 2nd edition […]
The large Epidauros Theatre – how did it sound with an audience and skene?
For practical reasons, most measurements of acoustics in ancient Greek theatres are made without an audience. Under those conditions much of the sound reaching the listener is in the form of reflections from the curved stone risers that form the seating. These reflections would be attenuated or eliminated by the audience. Let´s explore the Epidauros […]
Listening tests: linking objective room acoustic parameters with subjective human perception
Daniel de la Prida from Carlos III University in Madrid presented about his study into listening tests. He focussed on tests that can be used for linking objective room acoustic parameters with subjective human perception. Such tests have been in use for many years. However, different research usually employs different test protocols, with different operational […]
Acoustic metrics for innovative learning environments
Acoustics included as part of a major education research project Amanda Robinson has been a key researcher gathering acoustic metrics for innovative learning environments and she presented the findings at EIAS2023 this year. Traditional acoustic parameters are often used to describe the environment within learning environments. These include metrics such as ambient sound levels, reverberation […]
Optimal reverberation time in classrooms (Italian schools)
Arianna Astolfi Associate Professor at Politecnico di Torino, Department of Energy Torino, Italy has worked with acoustics since 2000. Optimal reverberation time in classrooms in Italian schools is her latest initiative. The study background and scope Arianna shared her thoughts and findings from a large study of Italian classrooms. This was specifically motivated to see […]
The effect of sound absorbers and diffusers in ordinary public rooms
Introduction Emma Arvidsson, Researcher and PhD ”Acoustic Design with Regard to Human Perception” presented her recent Phd study at EIAS2023. She focused on the objective and subjective aspects of acoustic design in ordinary rooms. Aiming to optimize room acoustics and examining the effects of different sound absorbers and diffusers. ‘Acoustic design plays a crucial role […]
Active room acoustics through electroacoustics: Amadeus Acoustics
One of the most common questions that you will hear in active room acoustics is: “what would be the best reverberation time for my room and how do I get there?”. The counterquestion needs to be: “what do you want to do in your room?”. And therein lies one of the common problems for room […]
