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’. 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 chains of thought […]
To create a school environment that works well from an auditory perspective, the acoustics must meet the needs associated with the purpose of the premises. Good acoustics are an investment in teachers’ occupational wellbeing, learning and comfort. “I have teaching spaces that work well for me.“ This is what Heikki Ylhäinen, fifth-grade teacher for a […]
Professor Arianna Astolfi’s tireless work within the field of architectural acoustics culminated in the publication of the Italian acoustic standard for schools, UNI 11532-2. This standard broke new ground in 2020 by including an expanded set of acoustic parameters ensuring optimal communication and speech perception in the classroom. Following the standard is now a legal […]
Sustainable building practices are here to stay and the number of building projects involving Thermally Activated Building Systems (TABS) is growing rapidly. However, from an office worker’s perspective, exposed concrete walls and ceilings create acoustic environments where it’s virtually impossible to communicate and concentrate. This detailed TABS Knowledge Guide explains how acoustic ceiling coverage impacts cooling […]
The Italian government has distinguished itself by allowing its building policies for school environments to be guided by overwhelming scientific evidence linking classroom acoustics to academic performance. Now the world has a strong example to follow in the shape of the newly published Italian acoustic standard for schools, UNI 11532-2. In 2020, Italy initiated a […]
What is good acoustic conditions in elderly care? Recently, a new study in an elderly care home in Denmark was finalized. The motivation for this study conducted by the two Architectural Engineers Cecilie Søgaard Petersen and Stine Sonne Nautrup was that we see demographic changes all over the world and this also means that the […]
IO ASCOLTO (I LISTEN) is an innovative research project tested in Turin to improve children’s learning abilities at school and intended to combat specific learning disorders experienced by children with special education needs (SEN) such as dyslexia – the inability to read words and texts quickly and correctly – which, according to AID (Italian Dyslexia […]
Designing a holistic indoor environment can be challenging. It will often entail several compromises between quality of different aspects of well-being. It is extremely rare that a solution comes along that both enhances indoor comfort, reduces complexity of design while also saving money and lowering emissions. It definitely is extremely rare, but it happens. Diffuse […]
We at Acoustic Bulletin writes for both acousticians and sound enthusiasts of all types and levels of experience. This post is for anyone who is just entering the field of room acoustics. It contains only very simple and basic descriptions of the the main terms, but should provide enough detail to give you a firm […]
In anticipation of the next Ecophon International Acoustic Seminar (EIAS) we bring you these 4 presentations on acoustic descriptors from EIAS 2015. Much in the world has changed since 2015, but the need for more technical descriptors in evaluating room acoustic quality is not one of them. Technical objective descriptors provides us to more accurately […]
