Maria Pettersson is a civil engineer from The Master Programme in Civil Engineering (2009) with a master's degree in Sound and Vibration (2009). Maria has also a university degree in Economic History (2010) and several courses in economics and languages.
After graduating, Maria worked as an acoustic consultant in various places in Sweden with theoretical as well as practical work, which gave Maria a broad base in the field of sound and vibration. Maria's next challenge was product development with employment with a major industrial company. Here, Maria worked mainly with attenuating the sound levels of different products, improving our speech intelligibility in noisy environments and with the development of new products in the ultrasound area. During this employment, Maria conducted some research, which resulted in that in 2019 she took a job at LTU as a doctoral student in building acoustics. At LTU, Maria works primarily with light wood constructions with the aim of improving their sound insulation. Among other things, Maria has developed a finite element model to be able to predict airborne sound insulation and experimented with metamaterials to be able to improve mainly the low-frequency sound insulation. These results will be published in 2021.
