Identifying the Acoustic Contribution to Interior Noise

The aerodynamic sources acting on a car side window, generally defined as the small wavelength sources such as turbulent eddies and boundary layer structures, are generally much larger in amplitude than the acoustic sources, those with longer wavelengths. So naturally you would expect that the aerodynamic sources have a much greater contribution on vehicle interior ...

Tuning Acoustic Quality of Audio Devices with Simulation

  When designing an audio device, the most important thing for an engineer to consider is the quality of the sound. Quality is what makes the device valuable and differentiates it from competitors. Audio device manufacturing companies experience extremely high product development costs due to repetitive and expensive physical testing. In addition to the need ...

Acoustic Simulation Helps Reduce Time to Qualify for New Noise Standard from 1 Year to 3 Months

Noise is a big problem in commercial and agricultural vehicles all around the world. While it is important for drivers to hear the sound of an engine, noise that is too loud can be uncomfortable. Government regulations on commercial and agricultural vehicles are heavy and also change from one country to another. For example, while ...
