Dr. Maria Klatte - focusing on specific needs for young listeners

2010-06-17T11:45:52Z

Dr. Maria Klatte had a lecture named "Effects of classroom acoustic on performance and well being in elementary school Children: A field Study". She presented the interesting results and had a great response after her lecture. Holger Brokmann took the chance to talk with her about the results and the importance of acoustic treatments in school buildings for children. Dr. Maria Klatte Listen to the Interview in german.

"The 24th April Bridge" creates a unique acoustic experience at conference

2010-06-17T10:11:35Z

Within 1km of the Congress centre the imposing road and rail bridge over the Tagus "Ponte sobre o Tejo" Listen to the unique soundfile which characterises the popular area surrounding the bridge. Colin Campbell spoke with Vitor Rosao Director at Doutorando Environmental Acoustics who explained.... ]]> Vuvuzelas! http://www.ecolaunch.se/Projects/Internoise10/Soundfile/bridge.mp3 Vitor kindly answered some questions which we have been asking many delegates, We've been asking...... 1: What brings you to Inter-noise 2010? Working with acoustics locally in Portugal 2: What topic or session is the most interesting so far? Why? Environmental noise particularly and the EU.CNOSSOS-EU it's my day to day work 3: What would you like to see at a future conference? More local acoustic experiences/features in an entertainment form. For example Fado singers at the conference would be good but acoustic examples which highlight cultural or engineering examples would be very engaging 4: If you had an unlimited research budget what would you explore/research? Exploring vertical water fountain acoustic barriers instead of fences in key city centre locations where they can become a tourist attraction as well including feature lighting, colours day/night effects. Also share the Brasil stadium research about noise levels to let the world realise that the present craze with blowing the Vuvuzelas (large World Cup horns) is a serious problem. 5: What advice would you give an end user planning a new building to ensure they optimize the acoustic environment? Consult an acoustic consultant as soon as possible for the best advice More specific questions: Education Are you being asked to design for a specific pedagogic style in classrooms? No How would your acoustic design differ if you were asked to take the changes of the pedagogical styles in account ? (Lecture / Group work) Look at the individual considerations Office / General How do you merge concrete core activation and acoustics in your consulting? No Do you see the need of a better acoustical descriptor than RT for open plan solutions - if yes, what would / do you use instead? yes, STI & Early Decay Time Healthcare Do room acoustics receive enough attention in hospital design? Not applicable What should be done to secure that room acoustic benefits are turned into reality? Not applicable Ecophon Acoustic Bulletin Have you heard of Ecophon's Acoustic Bulletin? No Are you a subscriber? No What could AB do to assist your day to day work or future work? Information about noise on people would be good Bonus question Who do you think will win the football World Cup? Portugal!

Interview with Lau Nijs from the Netherlands

2010-06-16T09:52:48Z

Guus Klamerek discusses Lau Nijs' paper following the "Classroom Acoustics" session yesterday. Lau's paper explored "Optimum absorption and vocal output in classrooms with U50" ]]> Delft University in the Netherlands, explores the parameter U50 which compares early sound reflections <50m/s with later and detrimental reflections >50m/s. This is similar to C50 and D50 but it also adds noise.

Lotta Johansson about ICU delirium

In the atrium of the conference building, Katrin met up with Lotta Johansson, who is a PhD study with Sahlgrenska Academy at Gothenbrug University. Lotta will make a presentation on the relation between sound and ICU delirium in intensive care units.(ICU).

INTERVIEW WITH ANNA PREIS

2010-06-16T07:46:56Z

An interview with prof. Anna Preis, Departament of Environmental Acoustics, Institute of Acoustics, Adam Mickiewicz University in Poznań, Poland. You presented at Internoise 2010 a paper entitled “Speech intelligibility as an annoyance index”. What’s the reason of such idea? - Noise annoyance is very subjective matter and individual estimations can vary a lot depending on mood or personal tolerance to noise of subjects. Moreover... ]]> How did you carry out your experiment? - We prepared a series of tests of speech comprehension in noise. Subjects had to cope with nine different types of distracting sounds trying to understand a sentence matrix test presented at constant level of 61 dBA. Distracting noise level was variable depending on subjects’ difficulties in comprehesion. What’s your conclusion? - Experiment shows that during communication type of distracting noise is important for its annoyance. In our test, speech comprehesion on the level of 50% was possible under train noise of LAeqT = 86 dB. When noise sample was changed from train to babble, similar level of comprehension was possible only to level of LAeqT = 68,8 dB. Results show that noise annoyance ranking of the noises by using the speech intelligibility scores are similar to the ranking used in field studies. However, there is a large difference between the noise annoyance ratings obtained in a field studies and speech reception threshold obtained for these nine noises. While in noise annoyance ratings collected in field studies there are large interindividual differences among participants’ annoyance judgments when it comes to speech intelligibility scores participants agree very well in their judgments.

The programme is a cooperation between Borås University College and Sahlgrenska Academy, both in Sweden. We asked Berit to give us a little bit of insight in the different studies that are planned. ]]> Who is Berit Lindahl? Berit is a certified nurse, university lecturer and Doctor of Medical Sciences & Post Doc Berit Lindahl's research area concerns the room design and the sound envrionment in intensive care units. She also conducts research that describes the home as the venue for enforcement - particularly where people are treated with the respirator / ventilator at home.
