This effect works not only in audio range of frequencies (Hz\u2013kHz), but also in ultrasound (MHz) and hypersound (GHz) frequencies, as long as the vacuum gap is made smaller as the frequencies increase.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The classic film \u201cAlien\u201d was once promoted with the tagline \u201cIn space, no one can hear you scream.\u201d Physicists Zhuoran Geng and Ilari Maasilta from the Nanoscience Center at the University of Jyv\u00e4skyl\u00e4, Finland, have demonstrated that, on the contrary, in certain situations, sound can be transmitted strongly across a vacuum region.
