About Acoustics

DEMCON bunova has developed a unique expertise in the area of sound & vibrations. In order to attenuate undesired effects like noise and vibrations, it is essential to analyse the source(s) of the sound and its propagation, to make any modifications to an existing design. Whether the cause of noise is related to a vibrating structure or a pulsating flow, at DEMCON bunova we have a wide variety of tools and expertise available to model and measure the sound propagation in a system. We can help you with a root cause analysis (RCA) by identifying the source and propagation of sound waves with visualization techniques using a SORAMA acoustic camera, perform complex modal analyses and sound propagation simulations by means of FEA (finite element analysis) and provide insight on structural dynamic properties through experimental modal analysis.

With this expertise, we can provide you with innovative and highly practical solutions in the field of product noise and vibrations.
Examples of acoustic and vibrations related problems include:

  • Product noise source identification
  • Power level measurements
  • Vibration testing and validation
  • Thermo-acoustics
  • Aero-acoustics
  • Noise and vibrations of machinery
  • Custom acoustic damper design
  • Prediction of sound radiation, absorption and transmission

The SORAMA sound camera enables us to visualise noise sources from large structures down to minuscule vibrations on printed circuit boards. Moreover, the use of in-situ measurements visualises transfer paths and gives insight into effective elimination of a noise source. We also use computational tools that allow detailed resolution of important acoustic phenomena. Simulations provide insight into source characteristics, sound propagation, sound spectrum and sound directivity.

Applications range from small products like cooling fans or piezo elements on printed circuit boards to large rotating or reciprocating equipment. Subsequent noise mitigation after determination of the source can be accomplished by reducing, damping or decoupling noise sources from the overall structure.

About DEMCON bunova

DEMCON bunova is an engineering agency with high-end expertise in the area of heat transfer, fluid dynamics, structural mechanics, acoustics and electromagnetism. We support clients from a wide variety of market sectors such as the process industry, semiconductor industry, oil & gas, maritime sector, heat exchanger applications and medical applications. With deep physical insights we aim to help you achieve your goals in research, development and engineering programs.

We combine fundamental physical knowledge from an analytical approach with Computer Aided Engineering (CAE) simulations tools from ANSYS, MATHWORKS, and COMSOL to setup, execute, analyze and evaluate numerical simulations.
The use of Computational Fluid Dynamics (CFD), Finite Element Analysis (FEM / FEA), Lumped Element Modelling (LEM) and Computational Electromagnetics (CEM) 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. This way of simulation-driven development increases the developments efficiency and reduces the product development time. Our services can therefore fully support you in the designing phase, from idea up to prototype.
