Ricardo Canto Leyton Click here to see video on TED.com website.]]> Julian Treasure is the chair of the Sound Agency, a firm that advises worldwide businesses -- offices, retailers, hotels -- on how to use sound. He asks us to pay attention to the sounds that surround us. How do they make us feel: productive, stressed, energized, acquisitive? Treasure is the author of the book Sound Business and keeps a blog by the same name that ruminates on aural matters (and offers a nice day-by-day writeup of TEDGlobal 2009). In the early 1980s, Treasure was the drummer for the Fall-influenced band Transmitters. tag:www.acousticbulletin.com,2012:/EN//2.742 2012-03-26T16:30:17Z 2012-03-26T16:39:00Z

Colin Campbell Tumlesalen i Nord Day Care Centre in Copenhagen Reduction of noise is the priority in Copenhagen in day care centres. Working environment studies show that noise is the primary cause for day care teachers leaving their profession. Copenhagen Municipality have initiated a study to demonstrate how to improve the Day Care sound environment for the future teachers and children. ]]> Table: Akustik ApS / Team Arbejdsliv Report Other results Besides the day care center ‘Børneborgen’ both ‘Nord’ and ‘Potteskåret’ showed great results – and the acoustician Per Møberg, concluded that neither organizational nor pedagogic changes will help minimizing noise issues if the acoustic treatment of a room is inappropriate or insufficient or if the room simply does not support the activity. In day care center ‘Potteskåret’ which is an open plan day care center they had to build up new walls – and smaller rooms called ‘cubes’ were acoustically treated with Wallpanels and freizes to lower LAeq. It was also necessary to build so called sound tunnels treated with Wallpanels (Super G) to lower the DL2 values. Image: Akustik ApS / Team Arbejdsliv Report The building Potteskåret’ used to be the old Bing & Grøndahl porcelain factory and with respect for its old use and legacy and its unique architecture it was impossible to make suspended ceilings. Results related to the teachers’ wellbeing were just as remarkable as the acoustical results: • Short-term sick leave has fallen. • Fewer employees would like to leave their profession • Self reported stress decreased from 52% to 25%. • The percentage of employees who feel annoyed by noise decreased from 63% to 16% In all, the project clearly concludes that teachers (and children!) in day care centres struggle with noise levels when the acoustic treatment is not good enough. If the wrong material is used or if the treatment is not sufficient it is impossible for the teachers to choose what they would like to do. When the acoustic conditions are bad – the teachers must really choose what is possible to do which is frustrating and one of the reasons why teachers want to leave their profession. On the contrary when the acoustics is sufficient – when the right materials are chosen, the work environment will be positive, the children’s play does not need to be restricted because of the noise levels and the teachers can perform higher quality work with reduced stress and annoyance. The "Plads til Alle" / "Room for Everybody" report by Akustik Aps (Per Moberg) and Team Arbejdsliv (Inger-Marie Weigman), can be down loaded in Danish here * "Lombard Effect" - (Lombard c1911) – Is the general term for the phenomenum and involuntary tendancy when the speaker raises their voice in order to hear themselves above the background noise. Wikipedia - The Lombard effect or Lombard reflex is the involuntary tendency of speakers to increase their vocal effort when speaking in loud noise to enhance the audibility of their voice.This change includes not only loudness but also other acoustic features such as pitch and rate and duration of sound syllables. This compensation effect results in an increase in the auditory signal-to-noise ratio of the speaker’s spoken words.]]> tag:www.acousticbulletin.com,2012:/EN//2.740 2012-02-18T08:28:48Z 2012-02-19T12:46:53Z
