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 […]
Classic Acoustics and Psychoacoustics – Similarities and Differences
Right after the grand opening of EIAS 2023, it was time for Alice Hoffman Senior Acoustician, PhD from Brekke and Strand, to make her entrance. She took us on a journey to see how Classical Acoustics can be compared to Psychoacoustics. Her own thoughts on this are that it often seems to be a lot […]
New Finnish acoustic standard paves the way
Finland paves the way for clear and science-based guidelines worldwide, with its revised standard for acoustic environments in buildings. Developed by the country’s leading acousticians, the standard is established in the business and among policymakers. In 2017, Finland’s Ministry of the Environment issued a decree on the Acoustic Environment of Buildings. Several parts of the […]
Digital design and acoustics at the School of Architecture
The iterative process of professionals providing expertise to the design students, using a file-to-factory approach and continual feedback, proved an effective way of learning and producing fast and high-quality prototypes at the School of Architecture, Sweden. Collaboration between architects and acousticians, and between designers and other specialists In line with our continued effort to raise […]
Sound environment in the Intensive Care Unit
Noise levels – how it is experienced by staff We have building regulations for room acoustics in hospitals in Intensive Care Units (ICU). But are they enough to create a good environment for both staff and patients? Recently a new study from Copenhagen hospitals was finalized so let’s take a look at some of the […]
