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 […]

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 […]
Learning environments – how do they sound?
For many years, research has shown that good room acoustics is crucial in learning environments and the discussion is no longer whether good room acoustics is to be prioritized or not but rather what indicators should reach what levels. Rasmussen et al [1] give an overview of the trend in reverberation time criteria for classrooms […]
Designing quality learning spaces in over 600 schools in New Zealand
As part of their School Property Strategy, New Zealand’s Ministry of Education (MoE) has recently revamped their acoustic standard for education, Designing Quality Learning Spaces (DQLS), and aims to implement it across 3,000 learning spaces in over 600 schools. The initiatives were recently presented at the Internoise 2022 conference by James Whitlock from Marshall Day […]
Lily Wang and Maslow’s hierarchy of needs: Wonderful key-note at Internoise in Glasgow.
If Michael Jackson was King of Pop – Lily Wang is Queen of acoustics! We feel so lucky to have been part of a legendary keynote presentation that made us laugh, wonder, reflect, and a bit star-struck! Lily has skills that go beyond her impressive professional merits: This lady excels on stage! Add to that […]
New Ph.D: Acoustic Design with Regard to Human Perception
Friday the 13th of May Emma Arvidsson (EA) did her Ph.D. dissertation at Lund’s University (Sweden) under the title ‘Acoustic Design with Regard to Human Perception’. Acoustic design of Ordinary Public Rooms From many years of research, we know that ordinary public rooms (classrooms and offices) where complex tasks such as learning or following long […]
New research shows that a lower reverberation time helps children cope with multi-talker listening situations
How children make sense of the complex signals they hear in the classroom depends partly on their hearing and cognitive abilities. But newly published research shows more about the important part played by the acoustic environment in this process; specifically, the role of reverberation time. The ability to make sense of what you are hearing […]
Diffusion or absorption?
The Subjective Experience Depending on Type of Acoustic Treatment Recently, PHD student Emma Arvidsson, published an article regarding different acoustic treatments in ordinary rooms and how they are perceived. The article concerns how people subjectively experience different acoustic environments and furthermore, if the experience was different depending on where in the room they were sitting. […]
Baltic-Nordic Acoustics Meeting 2021
The Nordic Acoustic Association and the Norwegian Acoustical Society invited scientists and engineers to attend the Baltic-Nordic Acoustic Meeting for 2021 this week and despite an online set-up the program consisted of keynote lectures, invited and contributed papers in structured parallel sessions. Some of the really interesting presentations are described here but you can find […]
Noisier teaching methods pose serious challenges for classroom design
Teaching methods shape the classroom sound environment Teachers of today have the shared goal of maximizing student engagement whilst maintaining a controlled sound environment. This has resulted in decades of innovation in educational approaches, classroom design and acoustic standardization. When additionally considering the influence of advancements in technological tools which have further augmented the field […]
