      Working mainly with environmental noise where I carry out acoustic studies on small planning cases to large infrastructure projects and urban noise mapping. I also carry out acoustic studies on noise from small businesses to large industries. For the majority of the case studies I use the software SoundPLAN. For industrial noise I also carry out near field measurements of noise sources which are subsequently used in the calculation software. Arbetar i första hand med samhällsbuller där jag utför bullerutredningar för mindre planärenden till stora vägprojekt och kommunkartläggningar. Jag gör även bullerutredningar för andra verksamheter och industrier. För de flesta utredningarna använder jag beräkningsprogrammet SoundPLAN. För externt industribuller gör jag även närfältsmätningar av bullerkällor som sedan används i beräkningsprogrammet. Show less
