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 […]
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 […]
American healthcare acoustics research presented at ICA 2019
Healthcare acoustics on the agenda What a privilege to attend ICA this year. Not only were we invited to a concert in the cathedral of Aachen but in the healthcare acoustics session, we had the opportunity to explore research from all over the world. Including 3 American papers on both noise reduction in neonatal care, […]
Finnish study finds that the sound environment affects children’s listening skills
Noise and a poor sound environment can hinder linguistic development of nursery school children, says Doctor of Philosophy Elina Niemitalo-Haapola in her dissertation. According to the study, more attention should be paid to children’s sound and learning environments. While working as a speech therapist, Elina Niemitalo-Haapola went to kindergartens, schools and homes to find out […]
Good acoustics as an extra source of income in restaurants
Internoise 2019, Madrid It’s all about money! Juan Negreira held a really inspiring presentation at Internoise 2019 – about how a room acoustic intervention in a restaurant lead to better income. Below are his findings and discussion and if you want to know more about the project and get access to the original paper, you […]
