I've previously mentioned two Swedish research initiatives on soundscapes and acoustic ecology, Urban Sound Institute and The Sound Environment Centre at Lund University.
There is also another somewhat similiar research programme, Soundscape: support to health (Ljudlanskap för bättre hälsa), which has an associated website with an introduction to acoustics, measurement and perception of noise, focused on health aspects. The introduction is in Swedish only, except for a course in engineering acoustics. An interesting twist is that the text is available in three versions: for curious people (nyfikna), for users (användare), i.e. architects, civil servants etc., and for specialists.
