Sound Transmission Breakthrough: Sending Sound Waves Through Vacuum

Scientists have demonstrated that sound can travel through a vacuum under specific circumstances and over extremely small distances. By transmitting sound waves between two zinc oxide crystals and converting them into ripples within an electric field, the researchers were able to transmit disruptions that mirror the frequency of the sound waves. However, the transmission is limited to distances no greater than the wavelength of a single sound wave, and the method is not always reliable. The findings could have implications for the development of microelectromechanical components in technology.
