Test codes for sound absorption measurements
Nils-Åke Andersson CEN/TC 126, Building acoustics, has created a working group, WG 11, to develop Test Codes for suspended, acoustic ceilings. WG 11 started its work about a year ago with Nils-Åke Andersson from Saint-Gobain Ecophon as convener and has now about 15 participants from around Europe. The reason doing this work is the problems […]
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 […]
Interesting article on auralization of spaces
Michael Vorländer from Aachen University in Germany contributed with a very interesting feature article on auralization of spaces in Physics Today (June 2009). It is important to be able to re-create the acoustic sensation of various kinds of spaces. The best possible future scenario would be to already at a design stage, be able to […]
Zebrafish might save human hearing!
The most common cause of hearing loss is damage to the hair cells in the inner ear. Once hair cells die, humans (like other mammals) aren’t able to grow new ones. Zebrafish, unlike humans, are able to regenerate their damaged hair cells. US researchers hope knowledge about this can help humans in the future. A […]

Shopping music – influencing you either you like it or not!
Earlier this year the founder of the “elevator music”, Muzak, went bankrupt! But the business of background music, making you shop more, is still successful. Matching the music with the target group is important! It is a matter of finding the appropriate sound level. Too high sound level might be disturbing. But then again, some […]
Peter Zumthor get Pritzker Prize
Peter Zumthor, Swiss architect, sometimes called “the poet of the silence”, was awarded a Pritzker Prize – one of the highest recognitions for architects. Zumthor is known for his approach to architecture, which assumes multisensual perception. While some have called his architecture quiet, his buildings masterfully assert their presence, engaging many of our senses, not […]
Noise and temporary deafness
Each of us exposed to noise of certain level will suffer so called Temporary Threshold Shift (TTS) – that is in fact temporary partial hearing loss. The TTS level and its duration depends on level of the noise, time of exposure and noise frequency band. There is no need to visit military firing ground to […]
