New report shows that European schools neglect their sound environment

A new report finds that far too many European schools neglect their sound environment. Noise harms children’s learning and health and creates inequalities for students with special needs. More schools should regularly measure noise levels and design according to acoustic standards and recommendations in order to provide optimal learning environments, that have the added benefit […]

Thermally Activated Building Systems (TABS) and acoustics

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 […]

Keeping noise levels stable, while the hustle increase excessively

If we improve an acoustic environment, usually we reduce noise level and reverberation time. When an unexpected situation occurs, reductions are not reached, but… Consider activities before making your conclusion! This study was conducted in 2021 in the Customer Service Centre of ČEZ in Děčín. ČEZ Group is the biggest energy company in the Czech […]

Ventilation through acoustic ceilings – What is diffuse ceiling ventilation?

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 […]

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 […]
