noise localization and reduction of respiratory system.

Medical blowers for respiratory systems must meet strict noise production requirements. One of our clients, a designer of respiratory systems, asked us to localize the source of the noise production. We found the noise producing areas and redesigned the resulting in a reduced sound pressure level and damping the frequency peaks.

Localizing noise

meeting noise requirements.

The transmission of sound through the blower is investigated. Measurements with an acoustic sound camera, in a broad frequency range and from multiple orientations are conducted. The frequency spectrum is analyzed and peaks are investigated.


Demcon multiphysics.

Demcon multiphysics is an engineering agency with high-end expertise in the area of heat transfer, fluid dynamics, structural mechanics, acoustics, electromagnetism and nuclear physics. We support clients from a wide variety of market sectors and help them achieve their goals in research and development with deep physical insights.

We combine fundamental physical knowledge from an analytical approach with Computer Aided Engineering (CAE) simulations tools from ANSYS, MATHWORKS, COMSOL, STAR-CCM+ and FLUKA to setup, execute, analyze and evaluate numerical simulations. The use of Computational Fluid Dynamics (CFD), Finite Element Analysis (FEM / FEA), Lumped Element Modelling (LEM), Computational Electromagnetics (CEM) and Monte Carlo simulations enables us to make a virtual prototype of your design. With these techniques we can simulate the fluid and gas flows, energy exchange, heat and mass transfer, stresses, strains and vibrations in structures and the interaction of electromagnetic fields with other physical aspects like heat generation. Simulation-driven product development increases the development efficiency and reduces the product development time. Our services can therefore fully support you in the designing phase, from idea up to prototype, from prototype to final design.
