21. Health effects of road traffic noise in childhood and adolescence
Abstract : Traffic noise is an increasing environmental exposure, primarily as a consequence of continuous urbanisation and growth of the transport sector. The burden of disease from noise is the second highest in Europe among all environmental exposures, after air pollution, and WHO recently proposed more strict environmental noise guidelines.

23. Methods for motor noise evaluation and control in electric vehicles
Abstract : Complete vehicle, system and component target setting for noise, vibration and harshness (NVH) are important activities within automotive product development. New challenges arise when electric motors are introduced into cars traditionally powered by internal combustion engines (ICE). READ MORE

24. Electric Machine Control for Energy Efficient Electric Drive Systems
Abstract : Over the past decade, electric vehicles has increasingly become an area of attention for both academia and industry, much due to challenges such as emissions legislation and the environmental impact of the transportation sector. The absence of the broadband noise from the internal combustion engine brings new acoustic challenges for electric propulsion applications. READ MORE

25. Vibrations in Lightweight Buildings - Perception and Prediction
Abstract : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. READ MORE
