Designing hospitals is a challenging task; anyone ever involved in such a project knows that! An increasing trend in Sweden, and probably other countries too, is to use ready-made modules for specialist areas. I have had the privilege to visit various building sites and completed projects where ready-made modules for Operating Rooms (OR) were used. […]

Internoise 2016 – do we have the right standards for elderly care?
I had the privilege to present a paper at Internoise 2016 based on an intervention study in a dementia clinic in Munich. The study was done in collaboration with Saint-Gobain Ecophon, the Technical University of Munich, the acoustic company PMI and the architect company Dietz Health Care Facilities. Do we have the right standards for […]
New world record for a reverberant space!
Photo: Allan Kilpatrick (RCAHMS) Trevor Cox, Professor of Acoustic Engineering at Salford University in the UK, recently visited and enormous former oil storage tank in Ross Shire in the Highlands of Scotland, where he recorded an incredible broadband reverberation time of 75 seconds across all the frequencies. It was 30 seconds at mid frequencies and […]

Reverberation Time is not enough….
Monika Rychtarikova Shortly after her presentation, Monika Rychtarikova was interviewed by Marielle Klijn. The title of her presentation was: “speech transmission index and articulation index in the context of open plan offices“. One of the conclusions of her session is that reverberation time is not an adequate quantity to fully describe the acoustical comfort. Please […]
Background to the European Standard EN 12354, part 6
In the latest issue of Acta Acoustica united with Acustica, Eddy Gerritsen (TNO) discusses engineering methods for the prediction of reverberation time and sound pressure levels in spaces with non-diffuse conditions. The assumptions and theoretical considerations behind the formulas in EN 12354-6 annex D are clarified. There is definitely a need for engineering models to […]
Reverberation time vs. amount of absorption in DIN 18041
German Standard DIN 18041 “Acoustical quality in small to medium-sized rooms” includes a table called “Guideline values for the free ceiling and wall surface areas to be covered with sound absorbers as a multiple of the room basic area (…)”. The table Download file presents for different room types the amount of sound absorbers to […]
