Scientists are working to develop a new type of sound-generating technology called “hypersound.” This technology uses mesoporous materials, an emerging type of material that has a high surface area, to create sound waves that are 1,000 times more powerful than traditional sound waves. Hypersound has the potential to revolutionize how sound is used in a range of industries, from medical to consumer electronics. It could be used to create directional sound waves, enabling sound to be focused on a specific area and heard only by the intended recipient. In addition, it could be used to detect objects that are out of sight or too small to be seen with the naked eye, such as bacteria. This could have a major impact on medical diagnosis, as well as search and rescue operations.
