This new research summary is now available and lifts out evidence from a variety of research studies around the world. These studies address a broad range of important aspects which need to be considered in learning environments. It is based on a recent extensive literature review by Professor Emerita Bridget Shield made for Ecophon. We […]
room acoustics
A good hospital is well built!
The population is aging, we are living longer and new methods of treatment are constantly emerging. Growth is sought in the productivity of nursing care and the skills it requires will be more demanding. This creates pressure to build resilient, functional, and technology-efficient hospital buildings with a long technical lifespan. Good facilities, their indoor climate, […]
Groundbreaking initiative from Quiet Mark with new Acoustics Academy launch
During the Surface Design Awards 2020 at the Business Design Centre in London, Quiet Mark launched their new Acoustics Academy. with a TED-style master-class event. The Acoustics Academy is a new online platform. which is intended to further equip and empower architects, builders and designers with an expertly verified guide of leading acoustic solutions for […]
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 […]
Reverberation room vs Anechoic Chamber
Here is a short film where our editor Juan Negreira demonstrates some aspects around the acoustic free field, and the broad range of acoustic dynamics which can be found between two acoustic opposites. This is a chance to experience and share difference between being inside a room coated with highly absorptive material versus in a […]
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 […]
Find out what a room can sound like – with the Ecophon Acoustic Calculator
Today almost all room acoustic calculations are based on the Sabine formula. Even though it is known that you often get different values when you compare calculations with actual measurements in a room. Therefore, Ecophon has developed a calculator in which the intention is to have more accurate acoustic values before measurements. The Ecophon Acoustic Calculator is […]
Euronoise 2018 – A cochlea in the floor carpet caught my eye
Euronoise 2018 was a great acoustic event, and we at Acoustic Bulletin are proud to have covered 6 sessions on room acoustics in particular. This is the last post written by our development engineer, Heléne Sallenhag – she has covered the session 18:3 – Voice accommodations in room acoustics and noise. How much would you spend […]
The effect of scattering in rooms with acoustic ceilings
Rooms with acoustic ceilings Today we see a lot of public rooms with acoustic ceilings – and that is good! But in these rooms especially the reverberation time and speech clarity does not only depend on the absorption material in the room. Scattering plays an important role for the room acoustic design and therefor furniture […]
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, […]
