Acoustic analysis
(under development)
Features
Sound flow can be analyzed based on the vibration analysis.
This is an analysis that optimizes the sound insulation mechanism from the generation and propagation of sound using a material model that takes into account the characteristics of the resin.
In order to design plastic parts with excellent acoustic characteristics, it is essential to establish Acoustic analysis technology.
What Acoustic analysis Can Do (1)
Understanding how vibration changes into sound
By inputting the analysis data obtained by Vibration analysis into Acoustic analysis, it is possible to reproduce how the vibration of the object is transmitted as sound and output the frequency curve at any location.
What Acoustic analysis Can Do (2)
Understanding how much sound penetrates
By calculating the frequency curve transmitted through the plastic cover using material data that considers viscoelasticity, the sound insulation performance of the materials can be evaluated.
