Sound environment in the Intensive Care Unit

Noise – 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 findings. […]

EIAS 2015 throwback: Four presentations on room acoustic descriptors

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 […]

Combination of Absorbers and Diffusers – An Experimental Study in a Classroom

This study provides information on how different acoustic treatments can be used to obtain different room acoustic qualities, and can be used to improve and fine-tune the room acoustic parameters for better speech and listening conditions in classrooms. The background overview The most common acoustical treatment in ordinary classrooms is a suspended sound absorbing ceiling. […]

Our Visual Focus (part 3) – Deafly Designed

What do modern human societies sound like? Have we neglected the soundscapes of human society, and how may our cultural focus on our sense of sight have affected how we design buildings? The World Health Organization (WHO) categorizes noise as the most significant environmental health threat right after air pollution (1). This should also be […]

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 […]
