Freddy Rietdijk

I grew up in a small town in the Netherlands called Goudswaard. Interested in physics I decided to study Engineering Physics in Rijswijk. An internship during my studies at the Dutch consultancy company DGMR in The Hague was the first real contact I had with the field of acoustics. My bachelor thesis on thermoacoustics I wrote during a second internship, for which I went as an Erasmus exchange student to the Swedish Technical Research Institute SP in Borås, Sweden.

After finishing my bachelor studies I worked for another year at DGMR on topics like tonal noise, source localization in the far field and sound recognition/classification. In 2011 I enrolled at the Sound & Vibration programme at Chalmers University of Technology, Gothenburg, Sweden. After the first year I went for a summer job to Oslo, Norway, where I worked at the acoustics group of Det Norske Veritas with ship noise. In the summer of 2013 I finished my studies after having written my master thesis while backpacking through the amazing northwestern part of India.

The SONORUS project then brought me to Zürich, Switzerland. I am working at the department of acoustics of the Swiss Federal Laboratories for Materials Science and Technology, commonly known as Empa. My research topic is ‘Auralisation of aircraft noise’. The goal of my research is to develop a tool for simulating aircraft noise in an urban environment. Work includes developing a source and propagation model as well as the final reproduction of the sound. Some physical phenomena to consider are Doppler shift, atmospheric absorption, wind and temperature gradients, reflections and diffraction. The research also encompasses estimating atmospheric influences like decorrelation due to turbulence.

Besides spending long and tough days on the work, I enjoy being in the outdoors. I like hiking in the mountains as well as climbing them. Luckily the mountains in Switzerland are slightly more challenging compared to those in my home country ☺.
