Areas of expertise

Acoustical holography is the main area of expertise of VVA. The software Acoustic Scanner^® uses the technique of the acoustical holography (NAH) to identify sound sources and reconstructing 3-D sound fields. We have more than ten years of experience in acoustical antenna techniques -- such as acoustical holography and beamforming.

• Digital computations and numerical simulations.
• Signal processing, wavenumber processing.
• Modelling industrial enclosures.
• Modelling industrial mufflers and fans.
• Techniques of sound intensity and structural intensity
• Prediction and analysis of structure-born and radiated sound
