Scientists at the Niels Bohr Institute have developed an ultra-thin membrane with tiny holes that allows sound vibrations (phonons) to travel with almost no energy loss, potentially revolutionizing sound and information transfer in quantum computing and sensors.

Physicists from the University of Jyväskylä have demonstrated that sound waves can be transmitted across a vacuum gap between two solids if the materials are piezoelectric. This phenomenon, known as tunneling, occurs when the size of the gap is smaller than the wavelength of the sound wave. The effect can be observed in a wide range of frequencies, from audio to ultrasound and hypersound. The researchers believe this discovery could have applications in microelectromechanical components and heat control.
