The solution to noise problems can be simple, say, a cooling fan can be run at a lower
speed. But to take cost-effective measures, often source characteristics and complex transmission paths need to be clarified. A balanced combination of testing and
simulation is typically needed. Akustikdoktorn has the
experience and the theoretical understanding to tailor adequate analysis schemes.
Sound transmission through partitions and source strength assessment is measured following ISO standards. But to understand which control measures are most appropriate, or how weight best can be reduced, more advanced techniques comes handy like intensity scanning or experimental transfer path analysis. Akustikdoktorn can support with such tests combined with independent recommendation of solutions.
In modern product development time to market is key. Well set-up simulation schemes can provide design guidance before prototypes are available. Akustikdoktorn has expert experience from virtual testing tools using Finite Elements, Statistical Energy Analysis as well as Ray-Tracing. Dr. Orrenius lectures in energy methods at KTH and has long experience using simulation tools., e.g for optimization of noise control measures with comparative studies of different designs. Akustikdoktorn has access to simulation tools for sound barriers, built up panels and walls as well as sound transmission in ducts.
