Speaker: Mikael Ögren

Acoustician and researcher. Working with models that can calculate noise levels from road and railway traffic flows, but also with the impact of noise on society; stress related health effects and social cost. Can not function without emacs, octave, gnuplot, qgis and python.

I'm an acoustician and has previously worked for SP, VTI, Chalmers and Semcon. At my current employer, Occupational and environmental medicine, University of Gothenburg, I work both with noise issues within the environmental health center and with research. I have worked with many different issues within the noise area, ranging from theoretical modeling to noise measurements in deep snow. The quietest sound I’ve made ??measurements on is the ticking of a giant digital display (about 20 dB at one meter) and the loudest must be the custom speaker “The Sphere” which produced sound levels around 120 dB before it caught fire. Economy has also become a part of my work. In particular, I’ve looked into the marginal costs of railway noise, i.e. what amount should you charge the train operators for the noise pollution they contribute to. Also, our health is affected by the acoustic environment in different ways. And there is a link to economy: poor health is expensive for the society. I have been an enthusiastic user of free and open source software since about 1995.
