Railway noise

We know railway: With 18 years experience from the railway sector Akustikdoktorn Sweden has the competence needed to analyse your needs and come up with adequate solutions. 

Railcar design:  We help specify and acoustically optimize challenging sources like diesel engines, electric motors, compressors and HVAC systems as well as aero-acoustic sources. We support with defining and optimizing light-weight and space effective noise control solutions for carbodies, such as damping layers and absorbing materials. We can model and design for low electric motor noise as well as predict transmission of carbody structures. 

Infrastructure: We work out the most effective control scheme: barriers, grinding, rail and wheel damping solution strategy, with respect to cost and other constraints.
