Room acoustics is an important factor to create sound, healing environments. Having a proper indoor climate can raise productivity by more than 15%[1] For more than a decade, ‘Evidence-Based Design (EBD) has been part of our DNA regarding building healthcare facilities. When it comes to the indoor climate we know that lighting, air quality, and […]
classroom acoustics
Language students in Slovakia now appreciate the importance of good acoustics
Improved language lessons at Bilingual Grammar School in Žilina Slovakia. Before the acoustic improvements, students had to cope with poor speech intelligibility and excessive reverberation during their language lessons. It was not only the students who complained about the poor acoustics, but also teachers were angry about the environment because they had to strain their […]
Healthcare and hearing impairment
People who are cut off acoustically from the external world not only lose their hearing, they are at risk of becoming socially and intellectually isolated. The less stimulation the brain receives, the more quickly its capacity diminishes[1]. Hearing impairment is connected to more than just hearing. Hearing loss and mental health Research all over the […]
Is it really possible to predict the room acoustic values in a non-diffuse room?
We made acoustic measurements as part of a remodelling of our training area at our head offices during the different phases of the acoustic treatment in the refurbishment. This is outlined in a previous Acoustic Bulletin post which highlighted the need for wall absorbers to remove the flutter echos, thus reducing the reverberation time and […]
Designing out “Chinook” flutter echoes in speech communication rooms
In September, it was a pleasure to present a work in progress “Optimising the acoustic design for a multi-purpose room used for speech communication activities” at ICA 2019 in Aachen. One of our inhouse head office rooms recently remodelled to accommodate a mixture of training functions. The sound environment for a room designed for speech […]
Better speech communication and learning in the classroom
At this years Transitions18 Education research seminar in Copenhagen, Viveka Årlander Lyberg Associate Professor at Lund University, presented the latest developments around Suvi Karjulainen’s PhD “Better communication and learning in the classroom”. This unique and applied study around the quality of speech communication for teachers and students also links to the investigation of the classroom […]
School acoustic research overview says minimise sound levels whilst maximising speech intelligibility
Professor Emeritus Bridget Shield recently presented a comprehensive school acoustic research overview at the Transitions18 education research symposium in Copenhagen. Bridget’s overview highlighted that the importance of acoustics in schools has been know about for a long time although the research has only really accelerated over the last 50+ years. BS looked at the typical […]
Euronoise 2018 – Reduce Noise to Improve Life
This year Euronoise was held in lovely Crete (close to the Knossos Palace) from the 27th to 31st of May – and in the impressive surroundings more than 700 delegates from all over the world attended more than 50 structured sessions in total. Room acoustics were on the agenda every conference day and this article aims to […]
School acoustics in 5 European countries
How does the view of school acoustics vary between five European countries? Working across several countries, it’s interesting to reflect on the differences we see in terms of the role of acoustics. In some countries the sound environment barely gets a mention in a building process, in others only in certain types of specialist spaces […]
Conference on inclusion and hearing impaired children
So, the iCARE research project (improving Children’s Auditory Rehabilitation) is coming to an end, and I had the privilege to participate in one of the last major milestones, recently executed (November 20-21 in Leuven, Belgium) – namely the iCARE conference. Professor Dr Astrid van Wieringen has been project managing all of us during these years, […]
