A recent study published in Physical Review B found that simulating the propagation of acoustic waves in composite materials with high-quality materials can be done using a new technique. This technique, known as a “wave function splitting method,” was developed by researchers from the Department of Physics at the University of Gothenburg in Sweden. The team of researchers was able to create simulations that accurately predict the behavior of acoustic waves in composite materials that are composed of two different materials. This method could be used to design materials that have specific sound absorption properties, making them suitable for applications in noise reduction and sound design. This new technique could open up new avenues for noise reduction and acoustic design.
