”Good evening, good morning or good afternoon…” – that was how Internoise 2020 was kicked off today Sunday the 23rd of August at 20.00 KST – live on youtube for the whole world to attend. For the first time ever Internoise is held as an e-congress and The Korean Society for Noise and Vibration Engineering […]

Heart rate is a medically recognised stressor – Noise reduction gives teachers a significant long-term benefit
This is not new, however it is a fundamental aspect to consider when designing optimal sustainable indoor environments. By measuring/recording the heart rate of teachers, an indicator of stress was apparent in lessons and also over a longer more sustained period. Here is a short insight overview on stress as stated by ASA (American Heart […]
How close are we to understanding how buildings affect our emotion?
Having met Isabella Bower while she was a research associate with the research team LEaRN we have been following her own research about how buildings affect our emotion. So we asked her to share insights from her research examining how design characteristics of buildings modulate neural networks involved in emotion regulation. Isabella’s work explores what […]
Effect of room acoustics on sound-field steady-state response (ASSR) measurements
PhD defense, effect of room acoustics Thursday the 28th of May 2020, Valentina Zapata-Rodriguez defended her PhD at DTU. Because of the Corona situation the PhD defense was planned to be online (on Teams) and I am impressed by the way Valentina handled this. Normally, you can interact with the audience and the committee in […]
Diffuse sound fields in healthcare facilities?
Diffuse sound fields – calculate right! Some years ago Saint-Gobain Ecophon published a new tool for calculating room acoustics. The tool makes it possible for the user to see both Sabine calculations on reverberation time, speech clarity, and room gain. It makes it possible for the user also to see calculations based on air flow […]
The impact of noise in education – a research summary
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 […]
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 […]
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, […]
Our visual focus (part 1) – Ocularcentrism
It is often stated that modern society is overly focused on the visual. But is this true and why is it even important? And when it really comes down to it, aren’t we mainly just visual beings or are we missing something here? We hear it again and again, sentences like: “We are visual creatures,” […]
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 […]
