We know railway noise. With 18 years experience from one of the world top competence centers in the field of railway acoustics Akustikdoktorn Sweden has the competence needed to analyse your needs, and come up with adequate solutions. Bombardier Transportation Global Centre of Competence for Acoustics and Vibration, one of the leading competence centers in the field, we have the competence and the network needed to analyse your needs and to work out effective solutions.

Infrastructure:  We work out the most effective noise control scheme with respect to cost and other constraints; including barriers, grinding as well as rail- and wheel damping measures. The result is typically a combination of measures, including programs for rail grinding and reprofiling of wheels, wheel and rail damping systems, and installation of way-side installations, Top of Rail smörjautomatersuch as noise barriers and machines for application of Top of Rail Friction modifiers..

Vibrations:  We also measure and assess ground vibrations and design a balanced combination of isolation measures to be applied in the ground as well as in building structures

Railcar design:  We support with setting of requirements at the purchase of rail vehicles. We set up technical specifications for subcontractors, define programs for follow-up and control, and propose effective measures for noise control and good sound quality. We can also provide the acoustic planning and design needed for control of noisy components such as electric motors and diesel engines, HVAC systems, compressors, and aero-acoustic sources. We have experience in minimization of vehicle weight with respect to mechanical load and noise reduction and we know how to make the most of damping systems and absorption materials. We also set up budgets for distribution of noise requirements and assessing acoustic performance.We analyze PA-systems regarding speech intelligibility (RASTI, STIPA) and sound comfort, and specify, model and design for good acoustic comfort.
