It beat older models at picking signals from noise, and hearing loss may break that network before raw sensitivity drops.<br/><br/>mugenradio.com 2026-10-16T14:01:50Z https://nostr.now/nevent1qqsxrjfmr55l2x7f8lr0slnylv9lt654jprqrz2kgu6m6he2dq5txvqzyp8dfsrhfmvgef439ew2phfhcdax3w3lzh8d2und8wsu2rqsf0esvlh575x A spider web inspired a new ear probe. Binghamton University engineers built a flow microphone that senses air movement instead of pressure, catching faint cochlea echoes used to spot hearing damage early.

Their brains leaned on general hearing circuits, not native-language ones, cutting interference.<br/><br/>mugenradio.com 2026-10-16T08:01:10Z https://nostr.now/nevent1qqsx0pv6cg6vaqnadskhwu32ut4sntdat2lwy9yqv992wr9rklck98gzyp8dfsrhfmvgef439ew2phfhcdax3w3lzh8d2und8wsu2rqsf0esvcr9x3n Oak Ridge engineers found a new way to spot hidden tunnels: put the sound source in a borehole below ground, not above it. A buried 40-foot steel tunnel produced a distinct subharmonic signal every time it was there.

Peak sensitivity: 3.2 kHz, close to human hearing&#39;s sweet spot. On land, they can hear ships, planes, even trains, sounds no one knew reached their ears.<br/><br/>mugenradio.com 2026-10-15T16:47:23Z https://nostr.now/nevent1qqsxmrymmuh22hzv68rgkxuu305ke606peu9m0r9d9l5dyl8h6c9rwqzyp8dfsrhfmvgef439ew2phfhcdax3w3lzh8d2und8wsu2rqsf0esv542040 EPFL engineers built tiny hollow cavities that turn sound into thrust: no motors, no electronics.

They get a little lower every single year. Nobody fully knows why: noisier oceans, maybe sexual selection.
