In 2025, scientists made sound behave like a rainbow, separating frequencies

By innovating with sound, scientists have successfully developed acoustic rainbows that divide sound signals across different pathways. Using tailored structures, they effectively transform white noise into a vibrant spectral array. Additionally, research teams have found methods to capture and redirect vibrational energy through synthetic fields, enabling the sorting and concentration of specific frequencies in solid materials. These breakthroughs pave the way for advanced acoustic wave manipulation techniques.
